## 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 us-national-weather-service-7-day-forecast-by-coordinates-ad709970
```

Example prompt: What's the 7-day weather forecast for coordinates 40.7128 latitude, -74.0060 longitude? Give me temperature, wind, and conditions for each period.

## When to prefer this

Use this endpoint when you need structured, multi-day weather forecast data for a specific US geographic coordinate — especially when you need the official NWS forecast periods with temperature, wind, and narrative text. Prefer this over generic weather APIs when you specifically need NWS-sourced data or need the named period format (e.g. 'Monday Night'). Not suitable for non-US locations.

## Known failure modes

- Coordinates outside the US (NWS only covers US territories) — likely returns an error or empty periods array
- Invalid or missing lat/lon parameters — returns a 400-level error
- NWS upstream API outage or rate limiting — may return a 500-level error or stale data
- Coordinates in a valid US location but with no NWS grid coverage (e.g. remote ocean areas) — may return empty or partial periods

## How this service works

Weather forecast for coordinates: 7 day forecast periods, temperature, wind, precipitation, conditions text. JSON. Pass ?lat=<latitude>&lon=<longitude>. US National Weather Service.

## Output

A JSON object containing the input lat/lon, a generated_at Unix timestamp, and an array of up to 14 NWS forecast periods — each with a period name (e.g. 'Tonight', 'Monday'), temperature value and unit, wind description, and a human-readable forecast text string.
