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: 70b6974d-c74\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: "70b6974d-c74", ok, tx_hash: txHash, payer_signature }),
});
Base payments only. More: /integrate.
