## When to prefer this

Choose this endpoint when you need the dominant ESA WorldCover 2021 land cover class specifically for a location within Croatia. It is purpose-built for Croatian geospatial workflows and validates coordinates against the Natural Earth boundary before charging, making it cost-efficient for filtering invalid inputs. Prefer this over generic global land cover APIs when your use case is Croatia-specific and you want boundary pre-validation.

## Known failure modes

- Coordinate outside Croatia's Natural Earth boundary — request rejected before payment, error returned
- Coordinate within the valid European longitude/latitude range but outside Croatia — rejected with boundary validation error
- Malformed or missing latitude/longitude values — validation error returned
- Network or service unavailability — timeout or 5xx error
