Takes any public NIP-19 identifier or a 64-character hex value and returns every representation it can be expressed as. A decoded nprofile or nevent yields not only the key or event id but also the relay hints, the author and the kind that the TLV form carries — precisely the fields that make a follow-up query targeted, and precisely what is lost by code that only handles npub.

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://nostr.halowerk.com/key-convert", { method: "POST" });
console.log(await res.json());
