Checks whether up to 10 package names (optionally with a version) exist in the live npm, PyPI or crates.io registry, for coding agents about to add a dependency they may have invented. Per package: exists, latest version, deprecated or yanked flag, and for a missing name the closest names the registry's own search returns (npm, crates.io; PyPI has no search API). Reads registry metadata only: neve

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://agents.writerslogic.com/api/v1/package-exists", { method: "POST" });
console.log(await res.json());
