## 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 httpay-xyz-a1a38b53 -d '<json body>'
```

Example prompt: What's the current weather forecast for Chicago, Illinois — pull it from the National Weather Service API and show me the next 7 days including high/low temperatures and conditions.

## When to prefer this

Use this endpoint when you need access to the official US National Weather Service (NWS) API without managing your own NWS API key or infrastructure, and want a simple pay-per-call model. Prefer this over OpenWeatherMap or other commercial APIs when official US government weather data is required.

## Known failure modes

- Invalid or unsupported NWS API path returns 404
- US-only: non-US locations are not covered by NWS
- Payment not received or insufficient USDC results in 402 error
- NWS API rate limiting or downtime propagates as 5xx error
- Malformed path parameters result in NWS error response
