Endpoint
GEThttps://claw402.ai/api/v1/crypto/cmc/quotesWhen to prefer
Use this endpoint when you need live CoinMarketCap quote data and want to pay per-call with USDC without registering for a CMC API key. Ideal for agents with a crypto wallet that need occasional price lookups without long-term API key management.
Side effects
- Invalid or unknown symbol/slug/id returns empty data array
- Payment failure (402) if wallet has insufficient USDC
- Invalid convert currency code returns error
- Missing required query parameter may return empty or error response
- Rate limiting or upstream CMC outage returns non-zero code
