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 ... is equivalent to uxc https://rest.coinapi.io --schema-url ....
