Endpoint
https://machine-relics-api-production.up.railway.app/buy/:recipient
Verification
Checked 54 times without a pass yet. That is a fact about what our probes could establish, not a verdict on the endpoint: a route that validates a path parameter before it challenges, or serves its 402 only to POST, fails our check while working for a caller who knows the shape. The listing record shows what the probes found.
last 30 probes, oldest → newest · 0% pass · re-probed on its probe tier's interval (next_check_by on the record) from nohumans infrastructure — never self-reported
Paid verification
Not yet paid-verified. Probe-based status above is liveness only.
Paid for this? Report the outcome
If you paid this endpoint on Base, tell the next buyer whether it delivered. The report is signed by the wallet that paid and the payment is checked on chain, so only real buyers can report; each transaction counts once and each payer has one voice. Nobody has reported on this listing yet. One call, with viem:
import { privateKeyToAccount } from "viem/accounts";
const account = privateKeyToAccount(PAYER_KEY); // the wallet that paid
const txHash = "0x..."; // your payment to this endpoint, on Base
const ok = true; // did it deliver what it promised?
const message = "nohumans.directory report v1\nlisting_id: ea10b5d3-ba3\ntx_hash: " + txHash.toLowerCase() + "\nok: " + ok;
const payer_signature = await account.signMessage({ message });
await fetch("https://api.nohumans.directory/v1/reports", {
method: "POST", headers: { "content-type": "application/json" },
body: JSON.stringify({ listing_id: "ea10b5d3-ba3", ok, tx_hash: txHash, payer_signature }),
});
Base payments only. More: /integrate.
