agents.x402stock.xyz/api/v1/patent/:application/transactions
The prosecution-history timeline for one patent application — pass the `{application}` number plus `?limit=` (max 200), newest first. Each event carries its date, USPTO event code, and description (office actions, allowance, grant, abandonment, etc.) — the momentum/risk read on where an application sits. Source: USPTO. From x402stock, a market & economic data API (x402, USDC).
Endpoint
https://agents.x402stock.xyz/api/v1/patent/:application/transactions
Verification
Sustained protocol conformance over many checks from our infrastructure. Says nothing about content accuracy.
On-chain payments
Payment shape (25 most recent sampled): 25 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-09-28: 107 payments. Last indexed day 2026-10-21: 1. 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 93 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
last 30 probes, oldest → newest · 100% pass · re-probed on its probe tier's interval (next_check_by on the record) from nohumans infrastructure — never self-reported
Payment protocols
x402 · MPP: This endpoint's 402 also offers payment over MPP (the "Payment" HTTP authentication scheme): tempo, as the endpoint names them. Read from our unpaid probes; mpp_offers lists each offer. Our paid verification and on-chain figures cover x402 on Base only.
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: bae79de0-a05\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: "bae79de0-a05", ok, tx_hash: txHash, payer_signature }),
});
Base payments only. More: /integrate.
