My usage (wallet-keyed purchase history)

Your own purchase history, keyed to the wallet that pays for the call — no wallet parameter, no signup: the x402 payment IS the identity, so nobody can read another wallet's profile. Returns totals, per-tool counts, per-chain breakdown, and recent receipts with settle tx hashes (independently verifiable on-chain). Requires an EIP-3009 payment (USDC on Base, Polygon, or Arbitrum); Solana/Stellar payments carry no signed payer the server can verify.

curl -i -X POST https://agent402.tools/api/my-usage \

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/my-usage", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "days": 30
  }),
});
