Api Endpoint

Onchain Query API

Live crypto price feed for agents: USD price, pool liquidity and 1h/24h change for ANY ERC-20 on Base or Ethereum, read straight from the DEX pool on chain (Uniswap v2/v3/v4, Aerodrome). Works for brand-new coins that price sites do not list yet. Pass token=0x... and chain=base|ethereum (no chain: Base, then Ethereum). Tickers like eth or btc also work. Cached 15 seconds. For many tokens use POST /price-batch (25 for 0.01 USDC).
