Example prompt: What's the dominant ESA WorldCover 2021 land cover class at latitude 52.52, longitude 13.405 in Germany?

## When to prefer this

Choose this endpoint when you need a single authoritative land cover class for a specific point in Germany based on the ESA WorldCover 2021 dataset. It is ideal for enriching location data with land use context, environmental assessments, or site classification tasks scoped to Germany. Prefer it over generic GIS APIs when you need ESA WorldCover 2021 specifically and want built-in German boundary validation to avoid wasted calls.

## Known failure modes

- Coordinate outside Germany boundary — rejected before payment with a boundary validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — input validation error
- Invalid or missing coordinate fields — schema validation error
- Payment failure or insufficient USDC balance — transaction error
- Upstream ESA WorldCover data unavailable — service error

## How this service works
