Reads the DKIM public key published at <selector>._domainkey.<domain>: key type, whether it is revoked (empty p=), decoded key size in bytes and a strength hint (about 1024-bit vs 2048-bit RSA), and basic syntax (v=DKIM1). Follows one CNAME, which large providers use. Does not check a signed message.

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.webintel-api.workers.dev/api/security/dkim-key-checker", { method: "GET" });
console.log(await res.json());
