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

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://chain.cyberwarex.com/price", { method: "GET" });
console.log(await res.json());
