Artefaktum

Look up an artifact by the external_key it was stored under (your own name for it, slashes allowed), in one of the wallet's projects. max_age_seconds turns an artifact older than that into a 404, for caching. Returns the artifact. Costs $0.005 in USDC. No signup: a wallet's first payment creates its account and a default project; the same wallet later reaches the same files.

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.artefaktum.dev/v1/artifacts/by-external-key/smoke%2F20261031225256", { method: "GET" });
console.log(await res.json());
