kraken-openapi-skill: Скилл для работы с API Kraken

--- name: kraken-openapi-skill description: Operate Kraken public market APIs through UXC with a curated OpenAPI schema, market-first discovery, and explicit private-auth boundary notes. --- # 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 1. 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` 2. Inspect operation help before execution: - `kraken-openapi-cli get:/0/public/Time -h` - `kraken-openapi-cli get:/0/public/Ticker -h` 3. 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> ...`. ## References - Usage patterns: `references/usage-patterns.md` - Curated OpenAPI schema: `references/kraken-public.openapi.json` - Official Kraken API intro: https://docs.kraken.com/api/docs/guides/global-intro
