Agent storefront

Things your agent can buy by itself

Every service below answers HTTP 402 with x402 payment terms. Your agent pays in USDC on Base and gets the result in the same request. No account, no API key, no human in the loop.

network eip155:8453 (Base) USDC on Base payTo 0x5f2dAbA9EA8B95d86195412A24F3Ab0168791696 agents.json

1Call the endpoint with no payment. You get 402 and the terms in the PAYMENT-REQUIRED header.

2Sign them with any x402 client and send the same request again with PAYMENT-SIGNATURE.

3The payment settles, then you get the goods plus a PAYMENT-RESPONSE header with the transaction. Failed work is not charged.

Set up once (official x402 client)

// npm i @x402/fetch @x402/evm viem
import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";
import { privateKeyToAccount } from "viem/accounts";

const account = privateKeyToAccount(process.env.PRIVATE_KEY); // a wallet holding USDC on Base
const pay = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(account) }],
});

Each service is its own site and its own deployment; this page only lists them. Prices are what each endpoint quotes in its own 402, so the endpoint is always the source of truth. Payments are real and go to the wallet above. Built by Matthew Busel.
