coingecko-openapi-skill: Скилл для работы с данными CoinGecko

--- name: coingecko-openapi-skill description: Operate CoinGecko and GeckoTerminal market data APIs through UXC with a curated OpenAPI schema, API-key auth, and read-first guardrails. --- # CoinGecko And GeckoTerminal Skill Use this skill to run CoinGecko market data and GeckoTerminal onchain DEX 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.coingecko.com/api/v3`. - Access to the curated OpenAPI schema URL: - `https://raw.githubusercontent.com/holon-run/uxc/main/skills/coingecko-openapi-skill/references/coingecko-market.openapi.json` - A CoinGecko Demo API key. ## Scope This skill covers a read-first market data surface: - API liveness checks - spot price lookup - asset ID discovery - market screener reads - trending reads - GeckoTerminal network discovery - onchain token price lookup - trending pool reads This skill does **not** cover: - paid or enterprise-only method families beyond the selected v1 scope - historical chart or OHLC families - portfolio, NFT, or onchain trade execution - the full CoinGecko or GeckoTerminal API ## Authentication The default host uses CoinGecko Demo auth with `x-cg-demo-api-key`. Configure one API-key credential and bind it to `api.coingecko.com/api/v3`: ```bash uxc auth credential set coingecko-demo --auth-type api_key --api-key-header x-cg-demo-api-key --secret-env COINGECKO_DEMO_API_KEY uxc auth binding add --id coingecko-demo --host api.coingecko.com --path-prefix /api/v3 --scheme https --credential coingecko-demo --priority 100 ``` Validate the active mapping when auth looks wrong: ```bash uxc auth binding match https://api.coingecko.com/api/v3 ``` ### Pro Host Override If you have a Pro plan, keep the same curated schema and create a separate credential, binding, and link: ```bash uxc auth credential set coingecko-pro --auth-type api_key --api-key-header x-cg-pro-api-key --secret-env COINGECKO_PRO_API_KEY uxc auth binding add --id coingecko-pro --host pro-api.coingecko.com --path-prefix /api/v3 --scheme https --credential coingecko-pro --priority 100 uxc link coingecko-pro-openapi-cli https://pro-api.coingecko.com/api/v3 --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/coingecko-openapi-skill/references/coingecko-market.openapi.json ``` ## Core Workflow 1. Use the fixed link command by default: - `command -v coingecko-openapi-cli` - If missing, create it: `uxc link coingecko-openapi-cli https://api.coingecko.com/api/v3 --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/coingecko-openapi-skill/references/coingecko-market.openapi.json` - `coingecko-openapi-cli -h` 2. Inspect operation schema first: - `coingecko-openapi-cli get:/simple/price -h` - `coingecko-openapi-cli get:/coins/markets -h` - `coingecko-openapi-cli get:/onchain/simple/networks/{network}/token_price/{addresses} -h` 3. Prefer narrow read validation before broader reads: - `coingecko-openapi-cli get:/ping` - `coingecko-openapi-cli get:/coins/list include_platform=false` - `coingecko-openapi-cli get:/onchain/networks` 4. Execute with key/value parameters: - `coingecko-openapi-cli get:/simple/price ids=bitcoin,ethereum vs_currencies=usd` - `coingecko-openapi-cli get:/coins/markets vs_currency=usd ids=bitcoin,ethereum order=market_cap_desc per_page=10 page=1` - `coingecko-openapi-cli get:/onchain/simple/networks/{network}/token_price/{addresses} network=eth addresses=0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48` ## Operation Groups ### Market Data - `get:/ping` - `get:/simple/price` - `get:/coins/list` - `get:/coins/markets` - `get:/search/trending` ### GeckoTerminal Onchain Data - `get:/onchain/networks` - `get:/onchain/simple/networks/{network}/token_price/{addresses}` - `get:/onchain/networks/trending_pools` ## 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 wallet, trading, or portfolio mutation support. - Demo and Pro hosts use different API-key headers. If the default Demo credential fails against the Pro host, create a separate Pro credential rather than reusing the Demo header name. - The Pro host needs its own auth binding on `pro-api.coingecko.com/api/v3`; creating only a credential is not enough for linked calls to send `x-cg-pro-api-key`. - CoinGecko public and Demo limits are tighter than Pro. Keep default examples narrow and avoid large paginated loops without explicit user intent. - The GeckoTerminal endpoints in this schema share the same API root and auth flow as the rest of the curated CoinGecko host contract. - `coingecko-openapi-cli <operation> ...` is equivalent to `uxc https://api.coingecko.com/api/v3 --schema-url <coingecko_openapi_schema> <operation> ...`. ## References - Usage patterns: `references/usage-patterns.md` - Curated OpenAPI schema: `references/coingecko-market.openapi.json` - CoinGecko API docs: https://docs.coingecko.com/reference/endpoint-overview - Authentication docs: https://docs.coingecko.com/reference/authentication
