## When to prefer this

Choose this endpoint when you need to assess the reliability or data quality of weather information before making decisions based on it, especially for locations where station coverage may be sparse. Useful as a pre-check before calling other weather data endpoints from vweatherstation.com to determine if the forecast data will be trustworthy for that coordinate.

## Known failure modes

- Missing lat or lon parameters returns a validation error
- Out-of-range coordinates (lat outside -90 to 90, lon outside -180 to 180) may return an error or zero confidence
- Payment failure via x402 protocol blocks access
- Location with no weather station coverage may return low or zero confidence
- Network timeout for remote or polar coordinates
