## 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-5cc63c96 -d '<json body>'
```

Example prompt: What's the National Weather Service forecast office and grid info for the coordinates 39.7456, -104.9994 — that's near Denver, Colorado?

## When to prefer this

Use this endpoint when you need to resolve a US latitude/longitude coordinate into NWS forecast office metadata as the first step before fetching actual weather forecasts — especially when you want a pay-per-call model without managing NWS API keys or rate limits directly

## Known failure modes

- Coordinates outside the US (NWS only covers US territory) return a 404 or error
- Invalid latitude/longitude format returns a 400 error
- NWS upstream API downtime causes 502 or timeout
- Payment not included or insufficient USDC returns 402 Payment Required
- Rate limiting or gateway errors return 429 or 503

## How this service works

API Gateway: US Weather (NWS) API

## Output

Returns NWS point metadata for the given coordinates including forecast office ID, grid X/Y coordinates, forecast zone, county, time zone, radar station, and URLs to retrieve the actual forecast and hourly forecast data
