Example prompt: What is the dominant ESA WorldCover 2021 land cover class at latitude 47.497, longitude 19.040 in Hungary?

## When to prefer this

Choose this endpoint when you need the official ESA WorldCover 2021 dominant land cover classification for a specific point in Hungary and want built-in coordinate boundary validation against Natural Earth Hungary borders. It is ideal for land use analysis, environmental screening, or geospatial data enrichment pipelines focused on Hungarian territory. Prefer it over generic global land cover APIs when Hungary-specific validation and low per-call cost ($0.003 USDC) matter.

## Known failure modes

- Coordinate outside Hungary boundary — rejected before payment with a validation error
- Latitude or longitude outside the European coverage range (34–72.5°N, -31.5–40.5°E) — schema validation error
- Malformed or missing coordinate fields — 400 Bad Request
- Payment failure or insufficient USDC balance — x402 payment required error
- Service unavailable or timeout — 503 or connection error

## How this service works

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

## Output

Returns the dominant ESA WorldCover 2021 land cover class label (e.g. Tree cover, Cropland, Built-up, Grassland, Shrubland, Wetland, Water body, Bare/sparse vegetation) for the queried coordinate within Hungary. Coordinates outside the Hungarian boundary are rejected before any charge is incurred.
