Token price by contract address
GET https://agent402.tools/api/coin-price-by-contract
Live price, market cap, 24h volume and 24h change for ERC-20 / SPL / other chain tokens looked up by CONTRACT ADDRESS on a named platform (ethereum, base, polygon-pos, arbitrum-one, optimistic-ethereum, binance-smart-chain, solana, avalanche, ...). Up to 25 contracts per call, any vs currency (default usd). The address-first sibling of crypto-price: use it when an agent holds a token address from a wallet, a DEX pair or a contract scan and has no coin id.
Warnings
Wallet mismatch The payout wallet in its live payment answer differs from its catalogue listing on the same network.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
