Aftermath Perpetuals

Aftermath API Integration

Production OpenAPI: https://aftermath.finance/api/openapi/spec.json Last validated: 2026-07-28 Production spec last hashed by the local change checker: 2026-07-28 Canonical docs UI: https://aftermath.finance/docs

Surface documented here:

• Aftermath HTTP/WebSocket API: 260 OpenAPI operations, as of 2026-08-19.
• TypeScript SDK: aftermath-ts-sdk v3.1.0.

Fast Routing

Choose one file first; do not load everything by default.

Default preference: start with native perpetuals endpoints (/api/perpetuals/*) because they expose the full Aftermath feature set. Use CCXT endpoints when you specifically need exchange-style compatibility. For a route not listed in a focused file, check endpoint-inventory.md before guessing a path.

1. CCXT endpoint work -> ccxt.md
2. Native perpetuals endpoint work -> native.md
3. TypeScript SDK method usage -> ../aftermath-ts-sdk/SKILL.md
4. SDK/API mismatch or migration -> ../aftermath-ts-sdk/references/backend-alignment.md
5. Signed wallet requests -> authentication.md
6. General wallet/auth/Sui/stable-kitchen/Dex Screener routes -> general-endpoints.md
7. Complete current operation list -> endpoint-inventory.md
8. API failures/retries -> error-handling.md
9. Trading safeguards -> safety-and-risk.md
10. DCA and spot limit orders -> dca-and-limit-orders.md
11. Staking -> staking.md
12. AMM pools -> pools.md
13. Coin and LP prices -> prices.md
14. Builder codes/gas pool/referrals/rewards/rebates/router/metastable/birdeye/dynamic gas/zkLogin/coins -> auxiliary-endpoints.md
15. Monitoring examples -> monitoring-patterns.md
16. Edge-case pitfalls -> gotchas.md

Integration Modes

Preferred by default: Native perpetuals (/api/perpetuals/*) for complete API coverage.

High-Risk Guardrails

• Sign signingDigest, not transactionBytes.
• Keep ID types strict: CCXT write accountId (object ID) vs native accountId (numeric).
• Send native BigInt fields using their exact "...n" wire format where required.
• Treat preview responses as success/error unions.
• Re-sync snapshots after stream reconnect before applying deltas.
• Serialize coin/gas-object-sensitive operations to avoid version conflicts.
• For service wallet-auth routes, sign the exact reusable terms message and carry IDs/filters as plain JSON; do not sign route-specific action objects.
• Treat gasBudget as MIST and distinguish service auth signatures from CCXT transaction-digest signatures.

Recent API Updates

Breaking (v3.0.0):

• Builder codes migrated from per-market integrator vaults to a global integrator registration: integratorAddress (address string) is replaced by integratorId (u32) everywhere, order-level builderCode.takerFee is now builderCode.integratorFee, config maxTakerFee is now maxIntegratorFee, and the integrator-vault fetch/create/claim routes are removed.
• Candle streaming moved to the general updates WebSocket (/api/perpetuals/ws/updates) via a marketCandles subscription; the dedicated /api/perpetuals/ws/market-candles/{market_id}/{interval_ms} route is removed.
• Candle intervals are CCXT-style timeframe strings everywhere: native candle-history uses resolution (was intervalMs) and CCXT OHLCV uses timeframe. See native.md for the full enum.
• SL/TP price fields are stopLossPrice and takeProfitPrice. Transaction inputs add optional triggerPriceType (0 index, 1 book mid, 2 mark) and per-SL/TP/stop-order builderCode; basic history responses contain only the prices.
• Rewards points response is { totalPoints } (float, was { points } integer) and /api/rewards/history now requires signed auth (bytes + signature); history entries carry eventType.
• Removed response fields: position makerFee/takerFee; vault totalCollateral/totalCollateralUsd; market params gasPriceTwapPeriodMs, forceCancelFee, gasPriceTakerFee, zScoreThreshold (replaced by priorityTakerFee); liquidation forceCancelFeesUsd. Price-feed IDs are numeric (u32) instead of address strings.

Additive (v3.0.0):

• TWAP orders: /api/perpetuals/account/twap-order-datas plus create-twap-orders / edit-twap-orders / cancel-twap-orders transaction routes.
• Client order IDs: clientOrderId(s) on limit/scale/cancel-and-place order placement, plus client-ID cancellation on supported transaction routes.
• Deterministic ordering, funding history, vault assistant capabilities, rebate tooling, scale orders, cancel-and-place, account sharing, and expanded account history.
• Vault TWAP orders: /api/perpetuals/vault/twap-order-datas plus create-twap-orders / edit-twap-orders / cancel-twap-orders vault transaction routes (mirrors the account TWAP surface).
• Rewards estimator: POST /api/rewards/expected-rewards returns forward-looking per-domain expected rewards for an epoch. The TypeScript SDK fixed this path in v2.2.1.
• Market metadata: POST /api/perpetuals/markets entries carry nullable static display metadata; displayName is omitted when unavailable.
• WS user subscription payloads now also stream twapOrders alongside stop orders.
• Vault discovery adds predeposit totals and per-vault TVL.
• Endpoint coverage now includes current DCA and spot limit-order flows, all staking routes, all pool routes, and all price routes.

Post-v3 service updates:

• Unified wallet authentication now accepts only the reusable terms message Aftermath Terms and Conditions; DCA/limit cancellation IDs are plain orderObjectIds and gas sponsorship accepts optional gasBudget.
• POST /api/perpetuals/vaults/config returns the dynamic vault protocol limits; send an empty JSON object {}. Do not hardcode lock, deposit, market, or pending-order limits; see native.md and the SDK's getVaultsConfig().
• Vault owner transactions can grant or revoke assistant capabilities through /api/perpetuals/vault/transactions/owner/grant-agent-wallet and /api/perpetuals/vault/transactions/owner/revoke-agent-wallet.
• GET /api/perpetuals/config serves network-specific AFLP/official-vault and default-collateral configuration.
• POST /api/pools/summary and POST /api/farms/summary batch and cache the object/stat data used by the frontend.
• CCXT metadata supports gasFromAddressBalance; deposit and withdraw support fromAddressBalance and toAddressBalance respectively.
• DCA/limit/router transaction construction and zkLogin creation changed shape; zkLogin accepts a base64 ephemeral public key.
• Public paths are kebab-case where normalized, including /api/rewards/expected-rewards; do not resurrect camelCase variants.
• Gas-pool failures now map to stable codes 2030–2033 (with 2018 as the shared-service fallback); reusable-signature failures are 2034.
• For perpetuals transactions with a named sponsor.walletAddress, scheduled execution gas is withdrawn from that gas pool and returned order gas is deposited back into it. With no named sponsor, returned gas goes to the account or vault owner.

24h Change Check

Use the local helper script to check the production OpenAPI after the 24h window.

• Use --force to bypass the 24-hour window; use --yes to query without an interactive prompt in CI or another non-interactive environment. EOF on a required prompt is an error rather than a successful no-op.
• Script: skills/api/scripts/check_api_changes.py
• Behavior: if less than 24h since Last validated, it exits without querying.
• If 24h+ elapsed, it prompts before querying: Query ... for API changes now? [y/N].
• It never auto-updates skill markdown files; it only records spec hash state in skills/api/.api-spec-state.json.
