## 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 x-pay-payment-quote-27fbc733
```

Example prompt: Before I submit the USDC payment, can you get me an X Pay quote for a GET request so I know the exact amount, wallet address, and network I need to send to on Base?

## When to prefer this

Use this endpoint when you need to retrieve current x402 payment parameters (amount, wallet address, network) before executing a micropayment for an X Pay API call. Prefer this over hardcoding payment values, as it ensures you have the latest quote and correct routing details. Ideal for automated agents building x402-compliant payment flows on Base with USDC.

## Known failure modes

- Missing or invalid 'input' object returns a 400 validation error
- Invalid HTTP method value (only GET, HEAD, DELETE allowed) returns a schema validation error
- Network or service downtime returns a 503 or connection error
- Malformed query parameters may result in unexpected quote response
