Endpoint
GEThttps://claw402.ai/api/v1/crypto/cmc/listingsWhen to prefer
Use this endpoint when you need real-time cryptocurrency market listings with rich filtering (price, market cap, volume, supply, percent change ranges) and want to pay per-call with USDC without managing API keys or subscriptions. Prefer over direct CMC API when you have a crypto wallet and want frictionless, keyless access.
Side effects
- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid query parameter values (e.g. non-numeric price range) — returns 400 Bad Request
- CoinMarketCap upstream outage — may return 502 or empty data array
- Exceeding rate limits or unsupported parameter combinations — returns error code in JSON body
- No results matching filter criteria — returns empty data array with code 0
