## When to prefer this

Choose this endpoint when you need a multi-day (1–7 day) weather forecast with daily temperature extremes, precipitation, and conditions for a specific city or geographic coordinate. Prefer it over a current-conditions endpoint when planning ahead rather than checking live weather. Use it when the user's question involves future weather — travel, events, agriculture, or logistics — rather than real-time readings.

## Known failure modes

- Invalid or unrecognized city name returns an error or empty result
- Days parameter outside 1–7 range is rejected
- Missing both city and lat/lon results in a validation error
- Network or upstream data unavailability may return a 503 or empty forecast
- Ambiguous city names (e.g. 'Springfield') may return results for the wrong location
