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:

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:

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> ....
