Example prompt: What is the dominant ESA WorldCover 2021 land cover class at latitude 52.2297, longitude 21.0122 in Poland?

## When to prefer this

Choose this endpoint when you need a single dominant land cover label for a specific point in Poland using the authoritative ESA WorldCover 2021 dataset. Prefer it over generic geospatial APIs when you specifically need Poland-validated, satellite-derived land cover classification at low per-query cost. Use sibling endpoints on the same domain for related soil, terrain, or built-up share metrics.

## Known failure modes

- Coordinate outside Poland boundary: rejected before payment with a validation error
- Latitude or longitude out of the European coverage bounds (lat 34–72.5, lon -31.5–40.5): schema validation error
- Malformed or missing coordinate values: request rejected with input validation error
- Network or service unavailability: HTTP 5xx error returned

## How this service works

Dominant ESA WorldCover 2021 class in the analysis area. The coordinate is validated against the Natural Earth boundary for Poland; results outside it are rejected before payment.

## Output

Returns the dominant ESA WorldCover 2021 land cover class for the queried coordinate within Poland, such as cropland, forest, grassland, built-up, wetland, water body, or similar classification labels derived from the 2021 satellite dataset.
