bank-validate

Cheap structural IBAN validation: ISO 13616 checksum + per-country structure/length. Returns valid plus, on rejection, a granular error_type (invalid_checksum, invalid_length, invalid_structure, invalid_country), the country and the format spec. Offline (schwifty, MIT); no network or keys. A cheap-first entry before the fuller /bank/verify fusion route.

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://api.agentstools.dev/bank/validate", { method: "GET" });
console.log(await res.json());
