Technical details
Endpoint
GEThttps://three.ws/api/x402/market-coin?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, pay-per-call cryptocurrency market data (price, market cap, ATH, rank) for either a named CoinGecko coin or a Solana SPL token by mint address, without needing a subscription API key. Ideal for lightweight agent workflows that need spot crypto data infrequently and want micropayment-based access.
Side effects
- Invalid or unknown CoinGecko coin ID returns an error or empty result
- Invalid Solana mint address (not a valid base58 public key) causes a lookup failure
- Neither 'id' nor 'contract' provided results in a missing required parameter error
- Payment of 0.001 USDC not received causes a 402 Payment Required response
- CoinGecko upstream outage may cause stale or unavailable data
