Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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
zero fetch --capability halowerk-europe-land-dominant-land-cover-class-250m-buffer-251e8854 -d '<json body>'
```

Example prompt: What's the dominant ESA WorldCover 2021 land cover class within 250 metres of latitude 51.5074, longitude -0.1278 in Europe?

## When to prefer this

Choose this endpoint when you need a fast, point-in-time lookup of the single dominant land cover category around a specific European coordinate at 250-metre neighbourhood scale, using the authoritative ESA WorldCover 2021 dataset. It is ideal for site screening, environmental assessments, and geospatial enrichment workflows where you need a single categorical label rather than a fractional share of multiple classes. Use it over share-based endpoints when you need the top-level classification rather than the proportion of a specific class.

## Known failure modes

- Coordinates outside the supported European bounding box (lat 34–72.5, lon -31.5–40.5) will result in an error or no-data response
- Non-numeric or malformed latitude/longitude values will cause a validation error
- Locations in border zones or edge cases near coverage boundaries may return no dominant class
- Network or service timeouts may occur under load
- Payment failures via x402 protocol will prevent request completion

## How this service works

Dominant ESA WorldCover 2021 class in the analysis area. The service evaluates a circular 250 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.

## Output

Returns the dominant ESA WorldCover 2021 land cover class (e.g. tree cover, shrubland, grassland, cropland, built-up, bare/sparse vegetation, snow and ice, permanent water bodies, herbaceous wetland, mangrove) that characterises the 250-metre circular buffer around the specified coordinate, expressed in standardised units consistent across the 30 covered European countries.
