# HALOWERK Europe Land – Dominant Land Cover Class (Parcel Polygon)

> HALOWERK Europe Land – Dominant Land Cover Class (Parcel Polygon) is a paid API for AI agents from euroland.halowerk.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-15).

Returns the dominant ESA WorldCover 2021 land cover class for a user-defined WGS84 polygon parcel across 30 European countries.

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-parcel-polygon-a1a15749 -d '<json body>'
```

Example prompt: What's the dominant ESA WorldCover 2021 land cover class for this parcel in Bavaria — the polygon has corners at [10.5, 48.1], [10.52, 48.1], [10.52, 48.12], [10.5, 48.12]?

## When to prefer this

Choose this endpoint when you need a single dominant land cover classification (not a fractional breakdown) for a custom polygon parcel in Europe, particularly when working with ESA WorldCover 2021 data for site assessment, agricultural eligibility, environmental review, or land use verification across 30 European countries. Prefer the circular-buffer sibling endpoints if you need a fixed-radius analysis rather than a custom parcel shape, or the share-based endpoints if you need the fractional composition of a specific land cover class rather than just the dominant class.

## Known failure modes

- Polygon outside the 30 supported European countries — returns error or null result
- Polygon span exceeds 0.25 degrees — rejected with validation error
- Fewer than 3 coordinate pairs supplied — schema validation failure
- Coordinates outside valid WGS84 bounds for the service (longitude -31.5–40.5, latitude 34–72.5) — returns error
- Malformed polygon array — parsing error
- Payment not settled via x402 protocol — request rejected

## How this service works

Dominant ESA WorldCover 2021 class in the analysis area. The service evaluates the bounded polygon supplied by the caller and returns standardized units across all 30 covered countries.

## Output

A single dominant ESA WorldCover 2021 land cover class label (e.g. cropland, tree cover, grassland, built-up, bare/sparse vegetation, permanent water, etc.) representing the most prevalent land cover type within the submitted polygon area, standardized across all 30 covered European countries.
