Endpoint

Verification

Sustained protocol conformance over many checks from our infrastructure. Says nothing about content accuracy.

On-chain payments

Payment shape (25 most recent sampled): 0 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 25 other calldata (facilitator batch, smart wallet, or unrelated — not classified).

Peak day 2026-10-12: 32 payments. Last indexed day 2026-10-18: 31. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 15 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.

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: 849a7a97-f99\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: "849a7a97-f99", ok, tx_hash: txHash, payer_signature }),
});

Base payments only. More: /integrate.
