## How to call it through Zero

```sh
zero fetch --capability x402-quickstart-loop2-11da22f3
```

Example prompt: Can you download the x402 quickstart bundle for me — I need the v2 Base USDC seller endpoint, EIP-3009 buyer client, and tests — grab the tar.gz format?

## When to prefer this

Choose this endpoint when you need a ready-to-run x402 payment protocol quickstart that includes both the seller (v2 Base USDC) and buyer (EIP-3009) sides along with tests, and want to pay per-call in USDC via the x402 protocol rather than managing API keys or subscriptions.

## Known failure modes

- Missing or invalid 'format' query parameter returns an error
- Unsupported HTTP method (e.g. POST) returns 405
- Payment not completed or x402 payment header invalid results in 402 Payment Required
- Network/worker downtime returns 5xx error
- Malformed request body returns 400

## How this service works

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

## Output

A binary tar.gz archive containing a complete x402 quickstart project: a README, a v2 Base USDC seller endpoint, an EIP-3009 buyer client, a deterministic product bundle, and a test suite.
