## 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-baltic-land-germany-cropland-share-d784b3e0 -d '<json body>'
```

Example prompt: What share of ESA WorldCover 2021 pixels are classified as cropland at latitude 51.5 and longitude 10.2 in Germany?

## When to prefer this

Use this endpoint when you need satellite-derived cropland land cover fractions specifically for points within Germany, based on the authoritative ESA WorldCover 2021 dataset. It is ideal for agricultural analysis, land use studies, site suitability assessments, or environmental reporting workflows that require a quick, pay-per-call lookup without managing raster datasets. The pre-payment boundary validation ensures you are not charged for out-of-scope coordinates.

## Known failure modes

- Coordinate outside Germany boundary — rejected before payment with a validation error
- Coordinate outside the European coverage bounds (lat 34–72.5, lon -31.5–40.5) — rejected with a range error
- Malformed or missing latitude/longitude fields — schema validation error
- Network or service availability issues — timeout or 5xx response

## How this service works

Share of ESA WorldCover 2021 pixels classified as cropland. The coordinate is validated against the Natural Earth boundary for Germany; results outside it are rejected before payment.

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels classified as cropland within the analysis area around the given coordinate. Only valid for coordinates within Germany; requests outside the German boundary are rejected before payment is processed.
