Onchain Query API

Spot USD prices for up to 20 crypto assets in ONE call: pass tickers (eth, btc, sol), CoinGecko ids, or 0x token addresses (priced from live DEX pairs). Each entry returns price_usd, 24h change and market cap where known; unknown symbols are reported, not silently dropped. Use it to value a portfolio, size a trade, or refresh a price table without 20 round trips.

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/prices", { method: "GET" });
console.log(await res.json());
