opendata402

Validate an IBAN: country, expected length, ISO 13616 mod-97 check digits, and the bank code part for common countries (NL, BE, DE, FR, GB, ES, IT, AT, CH, LU), plus the electronic and printed formats. Use it before sending a payment or storing bank details. Pure computation: the IBAN is not stored or forwarded, and no account existence check is made.

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://opendata402.com/v1/validate/iban", { method: "GET" });
console.log(await res.json());
