## When to prefer this

Choose this endpoint when you need ESA WorldCover 2021 tree cover share specifically for a point location within Lithuania. It is ideal for environmental assessments, land use analysis, and forestry surveys in Lithuania where boundary validation and low per-call cost matter. Use sibling endpoints on the same platform for other land cover classes (grassland, built-up) or soil properties at the same location.

## Known failure modes

- Coordinate outside Lithuania's Natural Earth boundary — request rejected before payment, no charge
- Coordinate within European coverage bounding box but outside Lithuania — validation failure
- Invalid latitude/longitude values outside the European coverage range — schema validation error
- Network timeout or upstream data unavailability
