## When to prefer this

Choose this endpoint when you need structured, machine-readable US weather forecasts in CSV format sourced authoritatively from the National Weather Service, particularly for data pipelines, spreadsheets, or tabular processing workflows. Prefer this over the Open-Meteo sibling endpoint when official NWS data provenance is required. Use the JSON or Markdown sibling endpoints if you need those output formats instead. Not suitable for non-US locations.

## Known failure modes

- Coordinates outside the US or territories → 400 outside_us_coverage (not billed)
- Invalid or missing latitude/longitude → 400 bad request
- NWS API unavailability → upstream service error
- Coordinates in US waters or unmapped NWS grid → potential 404 or empty forecast
- Malformed request body → 422 validation error

## How this service works

[concierge csv] 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 CSV-formatted response with rows representing current conditions and each forecast period (up to 7 days), including fields such as temperature, precipitation probability, wind speed/direction, and weather description, sourced from the National Weather Service. Non-US coordinates return a 400 error with code 'outside_us_coverage' and are not charged.
