--- name: coinapi-openapi-skill description: Operate CoinAPI market data reads through UXC with a curated OpenAPI schema, API-key auth, and read-first guardrails. --- # CoinAPI REST Skill Use this skill to run CoinAPI REST 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://rest.coinapi.io`. - Access to the curated OpenAPI schema URL: - `https://raw.githubusercontent.com/holon-run/uxc/main/skills/coinapi-openapi-skill/references/coinapi-market.openapi.json` - A CoinAPI key. ## Scope This skill covers a read-first market data surface: - current exchange rates - current quote snapshots - latest OHLCV candles - latest trades - latest order books This skill does **not** cover: - FIX, WebSocket, or MCP transport surfaces - write operations - the broader CoinAPI catalog ## Authentication CoinAPI uses `X-CoinAPI-Key` header auth. Configure one API-key credential and bind it to `rest.coinapi.io`: ```bash uxc auth credential set coinapi \ --auth-type api_key \ --api-key-header X-CoinAPI-Key \ --secret-env COINAPI_KEY uxc auth binding add \ --id coinapi \ --host rest.coinapi.io \ --scheme https \ --credential coinapi \ --priority 100 ``` Validate the active mapping when auth looks wrong: ```bash uxc auth binding match https://rest.coinapi.io ``` ## Core Workflow 1. Use the fixed link command by default: - `command -v coinapi-openapi-cli` - If missing, create it: `uxc link coinapi-openapi-cli https://rest.coinapi.io --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/coinapi-openapi-skill/references/coinapi-market.openapi.json` - `coinapi-openapi-cli -h` 2. Inspect operation schema first: - `coinapi-openapi-cli get:/v1/exchangerate/{asset_id_base}/{asset_id_quote} -h` - `coinapi-openapi-cli get:/v1/ohlcv/{symbol_id}/latest -h` - `coinapi-openapi-cli get:/v1/trades/{symbol_id}/latest -h` 3. Prefer narrow spot and latest reads before broader crawls: - `coinapi-openapi-cli get:/v1/exchangerate/{asset_id_base}/{asset_id_quote} asset_id_base=BTC asset_id_quote=USD` - `coinapi-openapi-cli get:/v1/quotes/current filter_symbol_id=BINANCE_SPOT_BTC_USDT` 4. Execute with key/value parameters: - `coinapi-openapi-cli get:/v1/ohlcv/{symbol_id}/latest symbol_id=BINANCE_SPOT_BTC_USDT period_id=1DAY limit=10` - `coinapi-openapi-cli get:/v1/orderbooks/{symbol_id}/latest symbol_id=BINANCE_SPOT_BTC_USDT limit_levels=20` ## Operations - `get:/v1/exchangerate/{asset_id_base}/{asset_id_quote}` - `get:/v1/quotes/current` - `get:/v1/ohlcv/{symbol_id}/latest` - `get:/v1/trades/{symbol_id}/latest` - `get:/v1/orderbooks/{symbol_id}/latest` ## 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. Do not imply order entry or market connectivity support. - Keep `filter_symbol_id`, `period_id`, `limit`, and `limit_levels` narrow unless the user explicitly wants larger pulls. - `coinapi-openapi-cli <operation> ...` is equivalent to `uxc https://rest.coinapi.io --schema-url <coinapi_openapi_schema> <operation> ...`. ## References - Usage patterns: `references/usage-patterns.md` - Curated OpenAPI schema: `references/coinapi-market.openapi.json` - CoinAPI REST docs: https://docs.coinapi.io/market-data/rest-api
