BitBooth Regex Test: pay 0.005 USDC, safely compile and run a regex against a corpus. Returns structured matches with capture groups, indices, and lengths. JS engine flags (g, i, m, s, u, y, d). Hard CPU deadline guards against catastrophic backtracking (ReDoS) — `regex_timeout` is reported instead of stalling. Stateless, no API key.

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://app.heinrichstech.com/v1/cdp/regex-test", { method: "POST" });
console.log(await res.json());
