File contents

Kraken REST Skill

Use this skill to run Kraken public market-data operations through uxc + OpenAPI.

Reuse the uxc skill for shared execution, auth, and error-handling guidance.

Prerequisites

uxc is installed and available in PATH.
Network access to https://api.kraken.com.
Access to the curated OpenAPI schema URL:
- https://raw.githubusercontent.com/holon-run/uxc/main/skills/kraken-openapi-skill/references/kraken-public.openapi.json

Scope

This skill covers a curated Kraken public surface for:

server time
asset pair metadata
ticker reads
OHLC candles
order book snapshots

This skill does not cover:

private account or trade endpoints in v1
Kraken FIX
broader non-core platform products

Authentication

Public market endpoints in this skill do not require credentials.

Kraken private REST endpoints use provider-specific header signing and nonce handling. Keep this v1 skill public-data-only until a reusable Kraken signer flow exists in uxc.

Core Workflow

Use the fixed link command by default:
- command -v kraken-openapi-cli
- If missing, create it: uxc link kraken-openapi-cli https://api.kraken.com --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/kraken-openapi-skill/references/kraken-public.openapi.json
- kraken-openapi-cli -h
Inspect operation help before execution:
- kraken-openapi-cli get:/0/public/Time -h
- kraken-openapi-cli get:/0/public/Ticker -h
Prefer narrow pair reads first:
- kraken-openapi-cli get:/0/public/Ticker pair=XBTUSD
- kraken-openapi-cli get:/0/public/Depth pair=XBTUSD count=20

Operations

get:/0/public/Time
get:/0/public/AssetPairs
get:/0/public/Ticker
get:/0/public/OHLC
get:/0/public/Depth

Guardrails

Keep automation on the JSON output envelope; do not use --text.
Parse stable fields first: ok, kind, protocol, data, error.
Treat this v1 skill as read-only.
Kraken pair naming can differ from other venues. Check AssetPairs before assuming symbol strings.
kraken-openapi-cli <operation> ... is equivalent to uxc https://api.kraken.com --schema-url <kraken_public_openapi_schema> <operation> ....
