mirrored listing x402 eip155:8453

Spot USD price for any crypto asset

Spot USD price for any crypto asset. Accepts a ticker symbol (eth, btc, sol), a CoinGecko id (ethereum), or an EVM token contract address. Returns the USD price plus 24h change, with market cap for listed assets, or liquidity, 24h volume and the top DEX pair for contract addresses. Cached 60 seconds so repeated calls in one agent workflow stay consistent with each other.
