AgentStall ZA

South African tax number validation: checks a 10-digit SARS VAT registration number or income tax reference number (format and modulus-10 check digit) and says which type it is. Format check only, not a SARS registration lookup; nothing is stored. Useful for invoices, supplier onboarding and form validation.

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://agentstall.nilesh-b54.workers.dev/v1/validate-tax-number", { method: "GET" });
console.log(await res.json());
