Example prompt: What's the combined share of permanent water, wetland, and mangrove land cover at latitude 47.14 and longitude 9.52 in Liechtenstein?

## When to prefer this

Choose this endpoint when you need a precise, paid, per-point query of combined water and wetland land cover share specifically within Liechtenstein, backed by ESA WorldCover 2021 data. It is ideal for environmental assessments, site screening, or geospatial enrichment workflows targeting Liechtenstein coordinates, especially when boundary validation before payment is important.

## Known failure modes

- Coordinate outside Liechtenstein Natural Earth boundary — request rejected before payment, error response indicating out-of-bounds
- Latitude or longitude outside the European coverage range (34–72.5°N, -31.5–40.5°E) — validation error
- Malformed or missing latitude/longitude fields — schema validation error
- Coordinate within European coverage range but outside Liechtenstein boundary — rejected with boundary error

## How this service works

Combined share of permanent water, herbaceous wetland and mangrove classes. The coordinate is validated against the Natural Earth boundary for Liechtenstein; results outside it are rejected before payment.

## Output

A numeric value (share/fraction) representing the combined proportion of ESA WorldCover 2021 pixels classified as permanent water, herbaceous wetland, or mangrove within the analysis area around the given coordinate in Liechtenstein. Coordinates outside Liechtenstein's Natural Earth boundary are rejected before any charge is incurred.
