Format check: is this IBAN (length for its country and mod-97 check digits), Australian ABN or ACN (check digits), or email address (syntax) well formed? Give { type: iban|abn|acn|email, value }. Returns valid with the normalised form, or the reason it is not. A format check only -- it does not say the account, business or mailbox exists. One purchase per check.

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://01mind.net/purchase/format-check", { method: "POST" });
console.log(await res.json());
