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-central-land-austria-cropland-share-eef04c15 -d '<json body>'
```

Example prompt: What share of the land around latitude 48.21 and longitude 14.02 in Austria is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Use this endpoint when you need ESA WorldCover 2021 cropland coverage data specifically for a point coordinate within Austria. It is pre-validated against Austria's official boundary, making it reliable for Austrian agricultural analysis. Prefer it over generic land-cover APIs when you need a precise, pixel-based cropland fraction from a globally consistent 2021 dataset.

## Known failure modes

- Coordinates outside Austria's Natural Earth boundary are rejected before payment is processed
- Coordinates outside the broader European coverage range (lat 34–72.5, lon -31.5–40.5) are rejected with a validation error
- Missing or malformed latitude/longitude inputs return a schema validation error
- Network or service unavailability may return a 5xx error

## How this service works

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

## Output

A numeric share (fraction between 0 and 1) representing the proportion of ESA WorldCover 2021 pixels in the analysis neighborhood classified as cropland, restricted to coordinates within Austria's Natural Earth boundary.
