Example prompt: What's the construction delay risk score for outdoor works in Chicago today — I need to know if wind, rain, or frost could hold up the project?

## When to prefer this

Use this endpoint when you need a single combined weather-based risk score specifically for outdoor construction delay assessment, combining wind, rain, and frost into one actionable index — rather than fetching raw weather data and computing risk yourself.

## Known failure modes

- Missing or invalid city name returns an error or empty result
- City not found in geocoding database returns 404 or error response
- Upstream weather data unavailable causes service failure
- Non-string city parameter causes schema validation error
