Technical details
Endpoint
POSThttps://funding.payforapi.com/crypto-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time or historical crypto token prices and want to query by flexible identifiers — ticker symbol, CoinGecko ID, or on-chain contract address. Especially useful when pricing obscure or newly listed DeFi tokens by contract address that may not be easily found by symbol alone. Paid per-call via x402/USDC on Base, suitable for agent-native micropayment workflows.
Side effects
- Unknown or unsupported token symbol returns an error or null price
- Invalid contract address format causes a lookup failure
- Historical date out of supported range may return no data
- Network or upstream CoinGecko API unavailability causes timeout
- Malformed chain:0x address format rejected
