Trbouma Safebox Safebox

Agent API Skill

Bootstrap

When starting a new session, fetch these files before executing any workflows:

Resolve paths from the repository root of the current checkout (current branch). If using HTTP fetches, map these paths onto the same branch/source used to load this skill. Do not rely on cached or summarized versions.

Do not load MS-01 by default. It is deprecated and retained only as a legacy reference.

For agent-operated MS-02 trading, treat the operator guide as the canonical workflow document for:

• seller/buyer role setup,
• end-to-end trade execution,
• kind-0 social profile publication,
• custom_handle assignment,
• name, display_name, nip05, and lud16 setup.

Purpose

Use this skill when an autonomous agent needs to operate a Safebox wallet through the header-authenticated Agent API (no browser cookies, no interactive UI).

Primary outcomes:

• Onboard a wallet from invite code
• Read wallet info and balance
• Read transaction history
• Create and pay Lightning invoices
• Pay Lightning addresses directly
• Execute zaps to notes/profiles via agent endpoint
• Send secure direct messages to npub/NIP-05 recipients
• Issue and accept Cashu ecash tokens
• Create recipient-first offer QR payloads so humans can send grants by scanning agent QR

Inputs

Required:

• base_url (example: https://skills.example.com)

Conditional:

• invite_code for onboarding
• access_key for authenticated wallet actions
• invoice string for pay flow
• lightning_address and amount_sats for direct LN-address pay flow
• event and amount_sats (or amount + currency) for zap flow
• amount (sat integer) for create/issue flows
• ecash_token for accept flow

Auth Model

• Authenticated calls require header: X-Access-Key: <access_key>
• Onboarding does not require X-Access-Key; it returns new credentials

DM Paths (Quick Reference)

Use these exact paths for private messaging flows:

• Read DMs: GET /agent/read_dms?limit=<n>&kind=1059
• Read replies to event: GET /agent/nostr/replies?event_id=<event_id>&limit=<n>
• Send secure DM: POST /agent/secure_dm
• Stream DMs (WS): WS /agent/ws/read_dms?limit=<n>&kind=1059

Minimum read example:

curl -sS \
  -H "X-Access-Key: ${API_KEY}" \
  "${BASE_URL}/agent/read_dms?limit=20&kind=1059"

Notes:

• kind=1059 is the default private DM transport for agent reads.
• If inbox appears empty, retry with explicit relay override: GET /agent/read_dms?limit=20&kind=1059&relays=wss://relay.getsafebox.app,wss://relay.damus.io,wss://relay.primal.net

CLI Surfaces (Use Both)

This repo now has two CLI entry points. Agents may use either, but should choose based on task:

• acorn / safebox (safebox/cli_acorn.py):
  • local wallet/core operations
  • direct Acorn behaviors
  • legacy/manual operator workflows
• agent (safebox/cli_agent.py):
  • header-authenticated /agent/* API workflows
  • market endpoints (/agent/market/order, /agent/market/orders)
  • DM/read_dms/zap receipt automation flows

Selection rule:

• Prefer agent for anything that maps to documented /agent/* endpoints.
• Use acorn for local core tasks not exposed through /agent/*.

Non-interference rule:

• Do not modify safebox/cli_acorn.py or safebox/acorn.py when extending agent CLI flows.

Execution Recipes

1) Onboard Wallet

1. Call POST /agent/onboard with invite_code.
2. Persist returned (REQUIRED before any further action):
   • wallet.access_key
   • wallet.nsec
   • wallet.seed_phrase
   • wallet.emergency_code
3. Treat response as sensitive secret material.
4. Immediately verify persistence:
   • confirm wallet.access_key is non-empty and saved in the agent’s durable identity store
   • confirm handle + access_key mapping is stored as an atomic pair
   • do not proceed to other API calls until the key is confirmed saved

Operational guardrail:

• If onboarding succeeds but key persistence fails, mark wallet as INCOMPLETE_ONBOARDING and retry/save before any production use.
• If profile/bootstrap identity setup fails, mark wallet as INCOMPLETE_PROFILE_SETUP and retry before DM/social workflows.

Expected response includes:

• wallet.handle, wallet.npub, wallet.home_relay
• session.access_token (optional for external systems; agent calls should still use X-Access-Key)

1a) Immediate Social Identity Setup (Required)

Right after onboarding, before social actions:

1. Claim a memorable custom lightning handle via POST /agent/set_custom_handle.
   • Choose a human-rememberable local-part (for example lumen, nova, pixel).
2. Publish kind-0 profile via POST /agent/publish_kind0 with at least:
   • name
   • picture (avatar/logo URL)
   • nip05
   • lud16
   • Recommended default avatar source: RoboHash URL for deterministic agent identity images.
   • Example: https://robohash.org/<stable-agent-seed>?set=set4
3. Identity rule:
   • nip05 MUST equal lud16 for Safebox-managed agent identities.
   • Example: lumen@safebox.dev for both fields.
4. Verify profile visibility:
   • GET /agent/nostr/kind0?identifier=<nip05>

Operational guardrail:

• Do not run DM-first or mention/zap response workflows until kind-0 includes valid nip05 + lud16 + picture.

Operator note:

• For the full identity and operator-facing setup procedure, use:
  • docs/operators/ms02-agent-operator-guide.md
• That guide is the canonical reference for:
  • custom_handle
  • name
  • display_name
  • lud16
  • MS-02 seller/buyer preparation

2) Read Wallet State

1. Call GET /agent/info with X-Access-Key.
   • Includes lightning_address derived from request host.
2. Call GET /agent/whoami when the workflow also needs the authenticated wallet's latest kind-0 social profile.
   • Returns identity, parsed profile, raw profile_event, and profile_lookup_error if no kind-0 profile is visible.
3. Call GET /agent/balance for lightweight polling or confirmation.
4. Call GET /agent/tx_history for recent transaction audit context.

2a) Set Wallet Custom Handle

1. Call POST /agent/set_custom_handle with:
   • custom_handle (required): desired local-part for wallet lightning address.
2. Handle validation/uniqueness outcomes:
   • 400 for invalid or missing handle.
   • 409 when the handle is already taken.
3. Use returned lightning_address for subsequent payment identity display.

3) Create Invoice (Receive Payment)

1. Call POST /agent/create_invoice with sat amount and optional comment.
2. Return invoice immediately to payer.
3. Use returned quote and status_path to monitor settlement:
   • poll GET /agent/invoice_status/{quote}
   • terminal state is quote_status: PAID
4. Optionally confirm final wallet state with GET /agent/balance or GET /agent/tx_history.

3a) MS-02 Ask Construction (Generic Entitlement Profile)

Use the dedicated constructor before publishing an MS-02 ask:

1. Prepare entitlement profile artifacts:
   • wrapper_ref
   • wrapper_commitment
2. Call POST /agent/market/ms02/construct_ask with:
   • required: wrapper_ref, price_sats, expiry, wrapper_commitment
   • optional: wrapper_scheme (defaults to nostr_keypair_v1)
   • optional: fulfillment_mode (defaults to provider_resolved_v1)
   • required for decryptable delivery: sealed_delivery_alg, encrypted_entitlement
   • optional: content_format (yaml default, plain supported)
3. Use returned:
   • content (human-readable ask preview)
   • tags, order_details_jcs, and ask_id (authoritative machine data)
4. Publish the constructed ask with POST /agent/market/ms02/publish_ask using the returned content and exact tags.

Human-readability vs authority:

• content is a preview for operators and includes warning text.
• Long identifiers are shortened in YAML display fields (*_display).
• Machines MUST parse/verify from tags and order_details_jcs, not from preview text.

Example:

curl -sS -X POST \
  -H "X-Access-Key: ${SELLER_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "wrapper_ref":"npub1...",
    "price_sats":21,
    "expiry":"2026-03-31T23:59:59Z",
    "wrapper_commitment":"7f3a9c2d41b8d4479c31c6f3a4b7a1e1d0f9d8c7b6a5e4d3c2b1a09182736455"
  }' \
  "${BASE_URL}/agent/market/ms02/construct_ask"

Publish example:

curl -sS -X POST \
  -H "X-Access-Key: ${SELLER_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "content":"ASK #MS02 ...",
    "tags":[["mkt","MS-02"],["side","ask"]],
    "kind":1
  }' \
  "${BASE_URL}/agent/market/ms02/publish_ask"

Consumer-side helpers:

• GET /agent/market/ms02/asks
  • list published MS-02 asks from relays
  • defaults to kind=1
  • accepts an alternate kind when needed
• POST /agent/market/ms02/parse_ask_event
  • parse and validate a full ask event or fetch by event_id
• GET /agent/market/ms02/settlement_receipts
  • fetch zap receipts for a published ask event id
• GET /agent/market/ms02/clear_order
  • evaluate receipts and determine whether the ask is OPEN, CLEARED, or EXPIRED
  • when cleared, identify the winning buyer deterministically
• POST /agent/market/ms02/deliver_wrapper_secret
  • deliver the wrapper secret to the cleared winner via secure DM

Consumer rule:

• agents MUST treat tags and order_details_jcs as authoritative
• agents MUST NOT treat the human-readable content preview as the source of truth

3b) MS-02 Entitlement Generator

Agent API helper endpoint:

• POST /agent/market/ms02/generate_entitlement

Purpose:

• generate provider-native entitlement inputs for the MS-02 wrapper flow
• normalize explicitly provided entitlement inputs without changing them

Behavior:

• if no values are passed, returns a generated test entitlement
• if one value is missing, generates only the missing value
• if both values are passed, returns the normalized values

Returns:

• entitlement_code
• entitlement_secret
• generation flags indicating whether test/default values were created

3c) MS-02 NIP-44 Entitlement Encryption

Agent API helper endpoint:

• POST /agent/market/ms02/encrypt_entitlement_nip44

Purpose:

• produce encrypted_entitlement for buyer_decryptable_v1
• encrypt the provider-native entitlement material to the wrapper public key

Inputs:

• wrapper_ref
• entitlement_code
• entitlement_secret

Returns:

• sealed_delivery_alg=nip44_v2
• encrypted_entitlement
• plaintext_payload_jcs

Usage rule:

• use the returned sealed_delivery_alg and encrypted_entitlement in POST /agent/market/ms02/construct_ask when fulfillment_mode=buyer_decryptable_v1

3d) MS-02 Buyer Decrypt + Validation

Agent API helper endpoints:

• POST /agent/market/ms02/decrypt_entitlement_nip44
• POST /agent/market/ms02/validate_buyer_delivery

Purpose:

• let the buyer recover entitlement_code and entitlement_secret from encrypted_entitlement
• let the buyer verify that the delivered wrapper secret actually matches the published ask

decrypt_entitlement_nip44:

• input:
  • wrapper_secret_nsec
  • either encrypted_entitlement, ask_event_id, or a full ask event
  • optional sender_pubkey when decrypting without ask lookup
• returns:
  • decrypted_entitlement
  • plaintext_payload_jcs
  • resolved wrapper_ref

validate_buyer_delivery:

• input:
  • wrapper_secret_nsec
  • ask_event_id or full ask event
• verifies:
  • derived wrapper_ref matches the ask
  • recomputed wrapper_commitment matches the ask
  • decrypted entitlement contains:
    • entitlement_code
    • entitlement_secret

3e) MS-02 Wrapper Generator

Agent API helper endpoint:

• POST /agent/market/ms02/generate_wrapper

Purpose:

• generate a fresh Nostr-native trading wrapper for MS-02
• or normalize an explicitly supplied nsec

Returns:

• wrapper_scheme=nostr_keypair_v1
• wrapper_ref
• wrapper_secret_nsec
• wrapper_commitment_hint

Usage note:

• wrapper_secret_nsec is sensitive and should not be logged
• wrapper_commitment_hint is not the full MS-02 wrapper commitment over entitlement data; it is only a wrapper-key-derived hint

3e) MS-02 Wrapper Commitment Derivation

Agent API helper endpoint:

• POST /agent/market/ms02/derive_wrapper_commitment

Purpose:

• derive the full MS-02 wrapper_commitment from:
  • wrapper secret
  • entitlement_code
  • entitlement_secret

Returns:

• wrapper_ref
• wrapper_commitment
• canonical commitment payload JSON (commitment_payload_jcs)

Implementation rule:

• this is the authoritative helper for the current MS-02 wrapper-commitment convention
• it binds raw wrapper secret material, not just the delivered nsec string

3f) Market Secret Hash Helpers

Use these helpers when an agent needs deterministic secret-hash derivation or verification without reimplementing the market hashing convention incorrectly.

Endpoints:

• POST /agent/market/secret_hash/derive
• POST /agent/market/secret_hash/verify

Purpose:

• derive a canonical market secret_hash from stable inputs
• verify that a provided preimage/input set matches a published secret_hash

Usage rule:

• prefer these helpers when constructing or validating market commitments that must match Safebox market conventions exactly
• treat the full returned secret_hash as authoritative
• never use shortened display hashes for matching, clearing, or redemption decisions

Currency Preflight (Before Address Payments)

1. Call GET /agent/supported_currencies.
2. Confirm requested currency appears with available=true.
3. Prefer SAT if rate metadata is unavailable for a fiat code.
4. Then call POST /agent/pay_lightning_address.

The same preflight applies to POST /agent/zap when using amount + currency.

Nostr Preflight (Before Event Zaps)

1. Call GET /agent/nostr/latest_kind1?nip05=<name@domain>&limit=<n>.
   • The nip05 target MUST already be present in the wallet kind-3 follow list.
   • If not followed, endpoint returns 403.
2. Read returned events[] and choose the target event_id (or event_id_hex / id).
3. Pass that value as event_id (or event) in POST /agent/zap.
4. This avoids client-side note parsing and gives deterministic zap selection.

Discovery variant:

• If the target is not in follow-list scope, use: GET /agent/nostr/discovery/latest_kind1?nip05=<name@domain>&limit=<n>

NIP-09 Delete Request (Kind 5)

Use this when the wallet author wants to publish a deletion request event for their own previously published events.

1. Call POST /agent/delete_request with at least one reference:
   • event_ids (list of note1... or 64-char hex ids), and/or
   • a_tags (list of NIP-01 coordinates: <kind>:<pubkey>:<d-identifier>).
2. Optionally include:
   • kinds (list of integers; recommended when known)
   • reason (free text, becomes kind-5 content)
   • relays override
3. Response returns published delete event metadata and final tags.

Notes:

• This publishes a NIP-09 request (kind=5); deletion enforcement is relay/client dependent.
• Agents SHOULD only request deletion for events authored by the same wallet pubkey.

Self Post Lookup (Authenticated Wallet)

1. Call GET /agent/nostr/my_latest_kind1?limit=<n>.
2. Optional relay override: &relays=<relay1,relay2,...>.
3. Use returned events[].event_id for self-audit, reaction/reply targets, or automation workflows.

Zap Receipt Lookup (NIP-57)

1. Call GET /agent/nostr/zap_receipts?event_id=<event_id>&limit=<n>.
2. Endpoint queries kind 9735 receipts filtered by #e=<event_id>.
3. For each receipt, inspect:
   • zapper_pubkey / zapper_npub (derived from zap request description.pubkey, fallback P tag)
   • zapper_identity_source to confirm identity provenance
   • lnurl_provider_pubkey / lnurl_provider_npub are receipt signer identities, not zapper identities
   • zap_request_raw (original embedded kind-9734 JSON string)
   • zap_request (parsed embedded kind-9734 object)
   • zap_amount_msat and invoice_amount_msat
   • amount_matches, description_hash_matches, matches_target_event
4. Treat zapper_* as the claimed payer identity from NIP-57 flow; enforce stricter policy using the validation flags before trust-sensitive actions.
5. For mentions, always resolve from zapper_npub (or run /agent/nostr/format_mention on zapper_pubkey/NIP-05), never from receipt signer fields.

Reply Lookup (Kind-1 Replies to Event)

1. Call GET /agent/nostr/replies?event_id=<event_id>&limit=<n>.
2. Endpoint queries kind 1 events filtered by #e=<event_id>.
3. Use returned fields:
   • replies[].event_id
   • replies[].pubkey
   • replies[].content
   • replies[].reply_to_event_ids
   • replies[].is_direct_reply
4. Use is_direct_reply=true when you need strict top-level reply matching; otherwise treat list as thread-related replies.

Reactions (NIP-25)

Use POST /agent/react for reactions.

A) React to a Nostr event (kind 7)

• Provide event_id plus optional:
  • content (+, -, emoji, or :shortcode:)
  • reacted_pubkey
  • reacted_kind
  • relay_hint
  • a_tag (for addressable target coordinates)
  • extra_tags

Behavior:

• Publishes a kind 7 event with target e/p tags.
• If multiple e/p tags are present, target e/p are placed last for NIP-25 compatibility guidance.

B) React to external content (kind 17)

• Omit event_id.
• Provide:
  • external_tags including at least one k tag and one i tag
  • optional content, extra_tags

Example external tags:

• ["k","web"]
• ["i","https://example.com"]

Behavior:

• Publishes a kind 17 event for external-content reactions.

Following Feed Lookup (Kind-1 from Follow List)

1. Call GET /agent/nostr/following/latest_kind1?limit=<n>.
2. Optional relay override: &relays=<relay1,relay2,...>.
3. Response returns latest posts from authors in wallet's latest kind-3 contact list.
4. Use returned events[].event_id for reaction/reply/zap workflows.

Followers Lookup (Kind-3 Reverse Discovery)

1. Call GET /agent/nostr/followers.
   • Default: returns followers of the authenticated wallet (self).
2. To query another identity, pass:
   • identifier=<nip05|npub|pubhex>
3. Optional controls:
   • limit=<n> (default 100, max 500)
   • strict=true|false (default true)
   • relays=<relay1,relay2,...>
4. Response fields include:
   • target_identifier
   • target_pubkey
   • count
   • followers[] with follower_pubkey, follower_npub, event_id, created_at, relay_hint

Strict mode behavior:

• strict=true verifies each candidate follower against their latest known kind-3 contacts event to reduce stale false positives.
• strict=false is faster and candidate-based, but may include stale follows.

Kind-1 Streaming (WebSocket)

Use these endpoints when an agent needs push-style updates instead of polling:

• WS /agent/ws/nostr/latest_kind1?nip05=<name@domain>&limit=<n>&poll_seconds=<n>&access_key=<key>
• WS /agent/ws/nostr/discovery/latest_kind1?nip05=<name@domain>&limit=<n>&poll_seconds=<n>&access_key=<key>
• WS /agent/ws/nostr/my_latest_kind1?limit=<n>&poll_seconds=<n>&access_key=<key>
• WS /agent/ws/nostr/following/latest_kind1?limit=<n>&poll_seconds=<n>&access_key=<key>

Access rule:

• ws/nostr/latest_kind1 only streams for identifiers in the wallet kind-3 follow list.
• ws/nostr/discovery/latest_kind1 is unrestricted by follow-list and intended for open lookup.
• For broad discovery, use ws/nostr/following/latest_kind1.

Auth notes:

• Preferred: send X-Access-Key header during websocket handshake.
• Fallback: pass access_key query parameter if client cannot set websocket headers.

Stream payload types:

• type=connected: connection accepted and stream initialized
• type=events: changed event set detected, includes full events[]
• type=heartbeat: no change detected at this poll interval

Post-deploy validation:

• Run WebSocket smoke checks in docs/specs/AGENT-API.md:
  • WS-CONN-001
  • WS-DATA-002
  • WS-HEARTBEAT-003
  • WS-POLICY-004
  • WS-FALLBACK-005
• Runnable command reference: docs/specs/WS-CONFORMANCE.md

Environment compatibility:

• Some browser/sandbox runtimes expose WebSocket but do not reliably return async stream callbacks to the agent.
• If WS streaming is unavailable or unreadable, fall back to polling with equivalent GET endpoints:
  • WS /agent/ws/read_dms -> GET /agent/read_dms
  • WS /agent/ws/nostr/latest_kind1 -> GET /agent/nostr/latest_kind1
  • WS /agent/ws/nostr/discovery/latest_kind1 -> GET /agent/nostr/discovery/latest_kind1
  • WS /agent/ws/nostr/my_latest_kind1 -> GET /agent/nostr/my_latest_kind1
  • WS /agent/ws/nostr/following/latest_kind1 -> GET /agent/nostr/following/latest_kind1
• Keep the same filters (nip05, limit, relays) and poll interval policy when using GET.

Market Order Discovery (Dedicated Path)

Use dedicated endpoint:

• GET /agent/market/orders?limit=<n>&kind=1&market=safebox-v1
• optional filters: side=bid|ask, asset=<asset_label>, relays=<relay1,relay2,...>

Behavior:

• Queries followed npubs only.
• Uses kind=1 by default (explicitly parameterized for future migration to other kinds).
• Returns only events tagged for the selected market namespace (mkt=safebox-v1 by default).

Follow / Unfollow Management

Safebox core supports following and unfollowing by identifier via:

• Acorn.follow(identifier, relay_hint=None, relays=None)
• Acorn.unfollow(identifier, relays=None)

Accepted identifiers:

• NIP-05 (name@domain)
• npub1...
• 64-char pubhex

Suggested workflow:

1. Follow identity (core or API route, if exposed).
2. Query GET /agent/nostr/following/latest_kind1 to verify feed changes.
3. Unfollow identity when needed and re-check feed.

Kind-0 Profile Lookup by Identifier

Use agent endpoint:

• GET /agent/nostr/kind0?identifier=<value>
• optional: &relays=<relay1,relay2,...>

Accepted identifier inputs:

• NIP-05 (name@domain)
• npub1...
• 64-char pubhex

Returns latest kind-0 event data with parsed JSON profile content:

• profile_event.id
• profile_event.pubkey
• profile_event.created_at
• profile_event.content (object)

Use this when an agent needs authoritative profile metadata before social actions (for example pre-zap context, identity checks, or local profile caching).

Social Identity Preflight (Before DM Flows)

Before running POST /agent/secure_dm or expecting stable sender resolution in clients:

1. Ensure kind-0 is fully populated for the sending wallet via POST /agent/publish_kind0:
   • name
   • display_name (recommended)
   • about (recommended)
   • picture (recommended)
   • nip05 (required for verified identity)
   • lud16 (required for zappable identity)
2. Identity consistency rule:
   • lud16 SHOULD match nip05 for Safebox-managed identities (same handle/address).
   • Example: nip05=lumen@safebox.dev and lud16=lumen@safebox.dev.
3. Verify profile visibility with GET /agent/nostr/kind0?identifier=<nip05_or_npub> before DM-heavy workflows.

Operational note:

• Incomplete kind-0 metadata can cause degraded or missing sender identity rendering in some clients and can destabilize DM-adjacent social workflows.

Read Private Messages (NIP-17 Gift Wrap Transport)

Use agent endpoint:

• GET /agent/read_dms?limit=<n>&kind=1059
• optional relay override: &relays=<relay1,relay2,...>

Behavior:

• reads incoming gift-wrapped messages using existing wallet record retrieval
• defaults to kind 1059 (private DM transport)
• returns newest-first messages with bounded limit

DM streaming variant:

• WS /agent/ws/read_dms?limit=<n>&kind=1059&poll_seconds=<n>&access_key=<key>
• same kind/relays semantics as GET /agent/read_dms
• emits connected, messages, and heartbeat frames

4) Pay Invoice

1. Call POST /agent/pay_invoice with BOLT11 invoice.
2. Check status == OK.
3. Use returned balance as post-payment state; optionally verify with GET /agent/balance.

5) Issue Ecash

1. Call POST /agent/issue_ecash with sat amount.
2. Capture returned ecash_token.
3. Treat token as bearer value until redeemed.

6) Pay Lightning Address

1. Call POST /agent/pay_lightning_address with:
   • lightning_address (for example alice@example.com)
   • either amount_sats (integer sats) OR amount + currency (floating-point amount in selected currency)
   • optional comment, tendered_amount, tendered_currency
2. Server performs LNURL resolution and payment using wallet core logic.
3. Verify status == OK and review fees_paid.
4. Use returned balance as post-payment state; optionally confirm with GET /agent/balance.

Why prefer this over manual LNURL flow:

• avoids client-side LNURL fetch/parse bugs
• avoids millisat conversion errors
• gives consistent behavior across LN-address providers
• centralizes error handling for unresolved/invalid addresses

7) Accept Ecash

1. Call POST /agent/accept_ecash with ecash_token.
2. Verify success and accepted_amount.
3. Confirm final wallet state via GET /agent/balance.

8) Zap Event/Profile

1. Call POST /agent/zap with:
   • event or event_id (one required): note1..., npub1..., NIP-05 (name@domain), or 64-char hex event id
   • either amount_sats OR amount + currency
   • optional comment
2. Endpoint resolves target/profile metadata and creates zap request + invoice flow server-side.
3. Verify status == OK.
4. Confirm post-zap state with returned balance and optionally GET /agent/tx_history.

Notes:

• Use GET /agent/supported_currencies before fiat-denominated zap requests.
• If zap metadata/profile lookup fails, endpoint returns 400 with Zap failed: ....

Zap by recent-event workflow:

1. Fetch recent events:
   • GET /agent/nostr/latest_kind1?nip05=trbouma@safebox.dev&limit=5
2. Pick events[i].id from response.
3. Zap selected event id:
   • POST /agent/zap with {"event_id":"<hex_event_id>","amount_sats":21,"comment":"nice post"}

9) Publish Kind-0 Metadata (NIP-01)

1. Call POST /agent/publish_kind0 with any subset of:
   • name, about, picture
   • optional: display_name, nip05, banner, website, lud16
   • optional: extra_fields (object), relays (array)
2. Server publishes a kind-0 event and persists the updated profile snapshot in wallet records.
3. Confirm returned event_id and profile fields.

Identity-separation warning:

• Treat each Safebox as a separate social identity surface.
• Do not copy the agent's own stable identity metadata into Safebox profiles if anonymity is desired.
• An agent may operate many Safeboxes with distinct kind-0 identities that should not be trivially correlated back to the controlling agent.

10) Publish Kind-1 Text Note (NIP-01)

1. Call POST /agent/publish_kind1 with:
   • content (required)
   • optional relays array override
2. Server signs and publishes a kind-1 event on configured relays.
3. Confirm returned event_id.

10a) Create Market Order (Bid/Ask, Kind-1)

1. Call POST /agent/market/order with:
   • side: buy/sell (also accepts bid/ask)
   • asset: market asset label/id
   • market: market namespace (mkt tag value), default safebox-v1
   • price_sats: integer sats
   • optional: quantity, order_id, content, flow, relays
2. Server publishes a structured market intent as a kind-1 event.
3. Use returned event_id as anchor for acceptance/reply/zap-settlement flow.

Mentions in posts:

• Preferred format: nostr:npub1... (NIP-27 URI form).
• Fallback format (client-dependent): @npub1....
• Recommendation: when onboarding a new client/app combination, publish a one-time compatibility post containing both formats and verify rendering on target clients (for example Amethyst/Primal) before standardizing.

Mention helper endpoints:

• POST /agent/nostr/format_mention
  • input: identifier + optional style (nostr_uri, at_npub, both)
  • output: normalized mention string and resolved npub/pubkey
• POST /agent/nostr/compose_mentions
  • input: base_text, identifiers[], optional style
  • output: mention-ready post content for direct use with POST /agent/publish_kind1

11) Send Secure DM (NIP-44 Gift Wrap)

1. Call POST /agent/secure_dm with:
   • recipient (required): NIP-05 (name@domain), npub1..., or 64-char pubhex
   • message (required): plaintext message to encrypt and send
   • optional relays array override (defaults to server PUBLIC_RELAYS)
2. Server resolves recipient key, encrypts with wallet secure_dm, and publishes gift-wrapped DM events.
3. Confirm status == OK and inspect returned relay list.

Example:

{
  "recipient": "alice@example.com",
  "message": "Hello from Safebox agent",
  "relays": ["wss://relay.damus.io", "wss://relay.primal.net"]
}

12) Publish Reaction (NIP-25 Kind 7)

1. Call POST /agent/react with:
   • event_id (required): target event id (hex or note id)
   • optional content (default ❤️)
   • optional target context: reacted_pubkey, reacted_kind, relay_hint, a_tag
   • optional extra_tags and relays
2. Server signs and publishes kind-7 reaction tags (e, p, k when available).
3. Confirm returned event_id and tags.

Example:

{
  "event_id": "<hex_event_id>",
  "content": "❤️"
}

13) Publish Reply (Kind 1)

1. Call POST /agent/reply with:
   • event_id (required): target event id (hex or note id)
   • content (required): reply text
   • optional target context: target_pubkey, target_kind, relay_hint
   • optional extra_tags and relays
2. Server signs and publishes a kind-1 reply with e/p/k reply tags.
3. Confirm returned event_id and tags.

14) Recipient-First Offer Request (Agent Shows QR)

Use this flow when a human Safebox user will send a grant to the agent wallet by scanning a QR shown by the agent.

1. Call POST /agent/offers/receive/create with:
   • optional ttl_seconds and compact_qr (default true)
   • optional include_ascii_qr=true to receive a terminal-renderable text QR in the same response
   • optional grant_kind and grant_name metadata (not required for handshake)
2. Display qr_text (or qr_image_url) to the human sender.
   • For terminal-native agents, print ascii_qr when requested.
3. Sender scans QR from Safebox offer UI.
4. Sender transmits grant through existing offer flow.
5. Agent waits for grant with:
   • GET /agent/offers/receive/{intent_id}/wait?timeout_seconds=<n>&poll_seconds=<n>
   • or websocket stream WS /agent/ws/offers/receive/{intent_id}?timeout_seconds=<n>&poll_seconds=<n>

Expected response includes:

• intent.intent_id, intent.expires_at
• recipient.recipient_nauth
• qr_payload, qr_text, qr_image_url
• optional ascii_qr (present only when include_ascii_qr=true)

Field usage:

• Agent management fields: status, intent, and recipient.
• Human scan fields: qr_text (raw recipient_nauth) or qr_image_url.
• Terminal render field: ascii_qr (human-agent boundary over terminal sessions).
• Structured optional context: qr_payload (for debugging/advanced clients).

Protocol note:

• Recipient-side nauth uses scope=offer_request.
• Scanner routing is expected to detect offer_request and redirect into records offer flow instead of generic accept flow.

Flow model note:

• Human-to-human and human-to-agent use the same relay/auth protocol primitives (21061 auth, 21062 transmittal).
• Human-to-agent is intent-driven; handshake completion and record ingest are separate stages.
• Do not treat handshake success as completion until ingest/persist succeeds.

Copy/Paste Quickstart For OpenClaw

BASE_URL="https://skills.example.com"
API_KEY="your-wallet-access-key"

curl -sS -X POST \
  -H "X-Access-Key: ${API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "ttl_seconds": 120,
    "compact_qr": true,
    "include_ascii_qr": true
  }' \
  "${BASE_URL}/agent/offers/receive/create"

Use returned ascii_qr for terminal display and qr_text (raw recipient_nauth) as canonical QR payload content.

Then wait for delivery using the returned intent.intent_id:

INTENT_ID="<intent_id_from_create_response>"
curl -sS \
  -H "X-Access-Key: ${API_KEY}" \
  "${BASE_URL}/agent/offers/receive/${INTENT_ID}/wait?timeout_seconds=120&poll_seconds=2"

Wait endpoint behavior:

• Returns status=OK with grant when a new grant is received during the window.
• Returns status=TIMEOUT when no grant arrives before timeout/expiry.
• Uses optional relays query override for record lookup.

WebSocket wait behavior:

• WS /agent/ws/offers/receive/{intent_id} emits:
  • type=connected when stream is active
  • type=heartbeat while waiting
  • type=received with grant when delivery is detected
  • type=timeout if no grant arrives before timeout/expiry
• Auth the same as other agent websockets:
  • preferred: X-Access-Key header
  • fallback: ?access_key=<key> query parameter
• HTTP fallback remains:
  • GET /agent/offers/receive/{intent_id}/wait

Terminal success criteria (recipient-first):

1. Handshake completes for the active intent.
2. At least one new transmittal record is observed for the matched presenter/context.
3. Record decrypt + put_record persist succeeds.
4. Wait endpoint/stream reaches terminal receive state (status=OK with grant or type=received).

Troubleshooting guidance:

1. If you see handshake logs but no terminal receive state, treat as incomplete ingest.
2. If the receiver loop repeats with seen IDs only, regenerate a fresh intent/QR and retry to avoid stale replay windows.
3. Timeout without grant means the sender path did not produce a matching transmittal for this intent window.
4. Validate completion using API state (wait/WS terminal payload), not sender UI success alone.

Compact behavior:

• compact_qr=true (default): qr_text stays raw recipient_nauth; structured metadata is available in qr_payload.
• compact_qr=false: QR includes explicit auth/transmittal relay metadata and KEM public metadata.
• Backward compatibility: compact is accepted as an alias for older clients.
• include_ascii_qr=true: embed text QR directly in create response (preferred for terminal agents).

Fallback text-QR helper:

• POST /agent/terminal/ascii_qr with body:
  • qr_text (required)
  • invert (optional, default true)
• Use when a flow returns only qr_text and terminal rendering is needed after the fact.

15) Sender-Side Offer Dispatch Lifecycle

Use this flow when the agent is the sender and needs explicit dispatch states.

1. Create offer:
   • POST /agent/offers/create with grant_kind, grant_name
2. Wait for recipient auth:
   • GET /agent/offers/{offer_id}/status?wait_seconds=30
3. If needed, capture recipient nauth manually:
   • POST /agent/offers/{offer_id}/capture
4. Send grant:
   • POST /agent/offers/{offer_id}/send
5. Check dispatch result:
   • GET /agent/offers/{offer_id}/delivery

Status semantics:

• offer_status: WAITING_RECIPIENT, RECIPIENT_READY, SENDING, SENT, FAILED
• delivery_status: PENDING, DISPATCHED, FAILED

Note:

• delivery_status=DISPATCHED means sender-side dispatch completed.
• It does not prove recipient-side application-level receipt acknowledgment.

Sender Flow Quick Test (Copy/Paste)

BASE_URL="https://skills.example.com"
API_KEY="your-wallet-access-key"
GRANT_KIND=34104
GRANT_NAME="Passport"
RECIPIENT_NAUTH="nauth1..."   # optional if using manual capture

1. Create offer:

OFFER_ID=$(curl -sS -X POST \
  -H "X-Access-Key: ${API_KEY}" \
  -H "Content-Type: application/json" \
  -d "{
    \"grant_kind\": ${GRANT_KIND},

    \"compact\": true
  }" \
  "${BASE_URL}/agent/offers/create" | jq -r '.offer.offer_id')
echo "OFFER_ID=${OFFER_ID}"

2. Check recipient readiness (or wait):

curl -sS \
  -H "X-Access-Key: ${API_KEY}" \
  "${BASE_URL}/agent/offers/${OFFER_ID}/status?wait_seconds=30"

3. Optional manual recipient capture:

curl -sS -X POST \
  -H "X-Access-Key: ${API_KEY}" \
  -H "Content-Type: application/json" \
  -d "{\"recipient_nauth\":\"${RECIPIENT_NAUTH}\"}" \
  "${BASE_URL}/agent/offers/${OFFER_ID}/capture"

4. Send offer/grant:

curl -sS -X POST \
  -H "X-Access-Key: ${API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{}' \
  "${BASE_URL}/agent/offers/${OFFER_ID}/send"

5. Confirm dispatch lifecycle:

curl -sS \
  -H "X-Access-Key: ${API_KEY}" \
  "${BASE_URL}/agent/offers/${OFFER_ID}/delivery?wait_seconds=10"

Expected terminal state:

• offer_status should be SENT (or FAILED)
• delivery_status should be DISPATCHED (or FAILED)
