## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh

```

Example prompt: What's the dominant ESA WorldCover 2021 land cover class at latitude 37.97, longitude 23.73 in Greece?

## When to prefer this

Use this endpoint when you need the single dominant ESA WorldCover 2021 land cover class for a specific point in Greece, rather than a pixel share breakdown (use the cropland-share or grassland-share sibling endpoints for proportional coverage). Ideal for quick site classification, environmental baseline checks, and enriching location data with authoritative ESA satellite-derived land cover labels. Prefer this over generic GIS APIs when you need validated, boundary-checked results specifically for Greece.

## Known failure modes

- Coordinate outside Greece boundary — request rejected with validation error before payment
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Malformed or missing coordinate fields — request returns a 4xx error
- Service unavailable or timeout — transient 5xx error

## How this service works

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

## Output

Returns the dominant ESA WorldCover 2021 land cover class label (e.g. Tree cover, Shrubland, Grassland, Cropland, Built-up, Bare/sparse vegetation, Water) for the analysis area centered on the provided coordinate. Coordinates outside the Natural Earth boundary for Greece are rejected before any charge is incurred.
