CN Data

RMB reference exchange rates. Returns the CNY cross table plus foreign-to-CNY rates for USD, EUR, JPY, HKD, GBP, KRW, SGD and AUD. No API key and no signup: call the endpoint, it answers HTTP 402 with the payment terms, pay per request in USDC on Base with any x402-compatible client or wallet, then retry the same request to get the data.

Call it from code

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://cn-data-x402.cn-data-x402-worker.workers.dev/cn/fx", { method: "GET" });
console.log(await res.json());
