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-nordic-land-denmark-cropland-share-02e85d8f -d '<json body>'
```

Example prompt: What share of the land around latitude 55.67, longitude 12.55 in Denmark is classified as cropland according to ESA WorldCover?

## When to prefer this

Choose this endpoint when you need ESA WorldCover 2021 cropland coverage fractions specifically for coordinates within Denmark. It is ideal for agricultural analysis, land suitability assessments, or environmental studies focused on Danish territory, and offers coordinate pre-validation against Denmark's boundary so invalid queries incur no cost. Prefer sibling endpoints on the same platform for other land cover types (wetlands, water) or soil properties.

## Known failure modes

- Coordinate outside Denmark's Natural Earth boundary — request rejected before payment with a validation error
- Latitude or longitude outside the broader European coverage bounds (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed or missing latitude/longitude fields — input validation error
- Network or service timeout — no result returned

## How this service works

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

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels within the analysis area classified as cropland, for the validated Danish coordinate. Coordinates outside Denmark's Natural Earth boundary are rejected before any charge is applied.
