Toll402

Offline validator for an Irish PPSN (Personal Public Service Number): checks the 7-digit + 1 check-letter (+ optional trailing 'A' or 'H' modifier letter) format and verifies the check letter using the published mod-23 weighted-sum algorithm (weights 8..2, optional modifier adds 9 or 72). Processes a single PPSN only; no network access or storage.

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://toll402.dev/v1/t/ppsn_ie_validate", { method: "POST" });
console.log(await res.json());
