Returns a complete x402 payment-gated quickstart bundle including a v2 Base USDC seller endpoint, EIP-3009 buyer client code, and deterministic product bundle with tests.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-quickstart-bundle-loop2-dc5899ce
```

Example prompt: Can you grab me the x402 quickstart bundle in zip format — I need the Base USDC seller endpoint, the EIP-3009 buyer client, and the test suite so I can start building a payment-gated API?

## When to prefer this

Choose this endpoint when you need a ready-to-run x402 protocol reference implementation on the Base network using USDC, specifically including both the seller (server) and buyer (client) sides with EIP-3009 authorization, plus tests. Prefer this over generic Web3 payment tutorials when you want a working, deployable code bundle rather than documentation.

## Known failure modes

- Payment not included or invalid — returns HTTP 402 with payment requirements
- Invalid format query parameter — may return 400 or unexpected content type
- Network timeout on Cloudflare Worker — returns 5xx
- Unsupported HTTP method — schema only allows GET, HEAD, DELETE

## How this service works

Complete x402 quickstart bundle: v2 Base USDC seller endpoint + EIP-3009 buyer client + deterministic product bundle + tests.

## Output

A binary bundle (e.g. zip or tar) containing: a v2 Base USDC x402 seller endpoint implementation, an EIP-3009-compatible buyer client, a deterministic product bundle definition, and a test suite — ready to deploy or study as a reference implementation.
