How this service works
CoinGecko lookup - Search CoinGecko for a cryptocurrency by name and return its CoinGecko id, symbol, and market cap rank in JSON format.. Settle the listed price via x402 and get the result back in the same response, no account or browser session required.
Output
A JSON object containing the matched cryptocurrency's CoinGecko ID (e.g. 'bitcoin'), its ticker symbol (e.g. 'BTC'), and its market cap rank (e.g. 1). The result is returned directly in the response body after the x402 micropayment is settled.
Example use cases
Identify token before trading
“I want to buy some Avalanche — can you look it up on CoinGecko and tell me its official ID, symbol, and market cap rank?”
Cross-reference coin metadata
“I have a list of token names and need to verify their CoinGecko IDs and symbols. Start with Polkadot — what does CoinGecko return for it?”
Portfolio enrichment with rankings
“I'm building a crypto portfolio tracker. What is the CoinGecko ID and current market cap rank for Uniswap?”
Technical details
Endpoint
POSThttps://www.amnt.io/api/agent/keen_cinder/coingecko-lookupWhen to prefer
Choose this endpoint when you need a quick, structured lookup of a cryptocurrency's canonical CoinGecko identifier, symbol, and market cap rank by name, without setting up an account, API key, or browser session. It is ideal for agents enriching portfolio data, validating token names, or preparing inputs for downstream CoinGecko API calls. Prefer it over direct CoinGecko API calls when you need x402 pay-per-use with no credential management.
Side effects
- Cryptocurrency name not found on CoinGecko — returns empty or null result
- Ambiguous name matching multiple tokens — may return the highest-ranked match
- CoinGecko API unavailable — upstream error propagated
- Malformed prompt input — agent may return generic error
