## 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 xx402-vercel-app-7fb2423f -d '<json body>'
```

Example prompt: What's the current weather in Tokyo right now?

Use this endpoint when you need weather data for any arbitrary global location and are operating in an x402 micropayment-enabled environment. It is well-suited for agents that can handle pay-per-call billing at $0.001 USDC per query.

## Known failure modes

- Invalid or unrecognized location name returns an error
- Payment of $0.001 USDC not provided or rejected results in 402 response
- Network or server error on Vercel hosting returns 5xx
- Malformed POST body returns 400 bad request
