## 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 nws-us-weather-forecast-json-pick-concierge-e429ca03 -d '<json body>'
```

Example prompt: What's the current weather and 7-day forecast for Seattle — the coordinates are 47.6062° N, 122.3321° W — using the NWS data?

## When to prefer this

Choose this endpoint when you need authoritative US government (NWS) weather data for US locations or territories with structured JSON output. Prefer it over the sibling Open-Meteo endpoint when official NWS data sourcing is important or required. Use the json-pick format when you want a pre-selected, concise JSON payload rather than CSV, Markdown, or custom formats. Not suitable for non-US locations — use the Open-Meteo sibling endpoint for international coverage.

## Known failure modes

- Coordinates outside the US and its territories return a 400 error with code 'outside_us_coverage' and no charge is applied
- Invalid or missing latitude/longitude returns a 400 validation error
- NWS upstream API outages may cause 502/503 errors
- Coordinates in US waters far from land may lack NWS grid coverage and return an error

## How this service works

[concierge json-pick] US weather: current + up to 7-day forecast from the National Weather Service (api.weather.gov). US and territories only; non-US lat/lon → 400 outside_us_coverage, not charged. Data only — not advice.

## Output

A JSON-pick formatted object containing current weather conditions (temperature, wind, sky conditions) and a structured up-to-7-day forecast from the National Weather Service, including daily high/low temperatures, precipitation probability, and weather descriptions for each period.
