APKCube APK Signing Cert Lookup

Every Android app signed by one signing certificate: look up a SHA-256 certificate fingerprint to find all packages and publishers that key has signed. Finds repackaged apps and related malware families, since a key that signed one repackaged app has usually signed others. Keyless pay-per-call in USDC on Base or Solana: no account or API 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://apkcube.com/api/v1/lookup/certificate/:fingerprint", { method: "GET" });
console.log(await res.json());
