x402 APIPassing, checked 57 min ago

nohumans.directory purchase history for one listing: every real USDC purchase the directory has made of it, oldest first — outcome, live quote vs listed price, settlement tx on Base, JSON/schema validity, freshness, normalised body hash — plus consecutive-pair deltas (delivery held/regressed/recovered, price held/moved, body same/changed). The verdict is a rule applied to this series; this is the series. Rule: https://nohumans.directory/methodology#purchases

curl -i -X GET "https://api.nohumans.directory/v1/listings/:id/purchases"
import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client().register(
  "eip155:8453",
  new ExactEvmScheme(privateKeyToAccount(process.env.AGENT_KEY)),

const pay = wrapFetchWithPayment(fetch, client);
