SiteCheck

A regular expression from a description, with examples that must match and examples that must not. The pattern is returned only when every example passes when tested in the service (one retry with the failures). Patterns with nested quantifiers are refused to avoid catastrophic backtracking. Examples are up to 10 strings of 300 characters each.

Call it from code

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://api.sitecheck-api.workers.dev/api/regex/generate", { method: "POST" });
console.log(await res.json());
