Use for anything needing an up-to-date Brazilian benchmark rate: pricing a loan, indexing a contract, converting USD/BRL. No body required. Returns Selic (Copom policy rate), CDI (interbank rate) and USD/BRL (PTAX sell rate), each with its reference date, straight from the BCB's own SGS API.

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://tools.miniframe.com.br/taxas-bcb", { method: "POST" });
console.log(await res.json());
