Iban Check

by IBAN Check in Productivity & SaaS

x402 APIPassing, checked 7 h ago

Validate an IBAN offline: country registry length, structure, and the ISO 7064 mod-97 checksum that catches what humans and spreadsheets actually get wrong — a transposed pair, a dropped character, an O typed for a zero. Returns the normalised and print-formatted forms, country, SEPA membership, and the bank identifier where the layout is known. Every rejection names WHICH check failed, so you know whether to fix the row or drop it. Structure only: a valid IBAN is not proof the account exists.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://402.com.tr/api/x402/iban-check?iban=GB82+WEST+1234+5698+7654+32'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://402.com.tr/api/x402/iban-check?iban=GB82+WEST+1234+5698+7654+32' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
JavaScript: pay and call
// npm i @x402/fetch @x402/evm viem
import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

// Pays at most $0.002 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.002" });
registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? ToolVet checks it first for $0.005. Pay for that from a separate
// client: this one is capped at $0.002 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2F402.com.tr%2Fapi%2Fx402%2Fiban-check
const res = await pay("https://402.com.tr/api/x402/iban-check?iban=GB82+WEST+1234+5698+7654+32");
console.log(res.status, await res.text());
Python: pay and call

with x402_requests(client) as session:
    res = session.get("https://402.com.tr/api/x402/iban-check?iban=GB82+WEST+1234+5698+7654+32")
