Certificate transparency search

Search public Certificate Transparency logs for every cert issued to a domain. Two independent public CT search services are queried, the second only if the first is slow or fails, and `source` names the one that answered (their coverage windows differ). Returns the cert list plus a deduped subdomain set extracted from the SANs - the fastest way to enumerate subdomains for a security audit. No key

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://agent402.tools/api/cert-transparency", { method: "POST" });
console.log(await res.json());
