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-liechtenstein-cropland-share-80c0c4b1 -d '<json body>'
```

Example prompt: What share of the land around latitude 47.14, longitude 9.52 in Liechtenstein is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Use this endpoint when you need granular, pixel-level cropland fraction data specifically for coordinates within Liechtenstein, derived from the authoritative ESA WorldCover 2021 dataset. It is ideal for agricultural analysis, land use auditing, and environmental assessments where Liechtenstein-specific boundary validation and pre-payment rejection of invalid coordinates are important. Prefer it over general land cover APIs when you need Liechtenstein-scoped data with built-in coordinate validation.

## Known failure modes

- Coordinate outside Liechtenstein boundary: request rejected before payment, with a boundary validation error
- Coordinate outside European coverage bounds (lat 34-72.5, lon -31.5 to 40.5): validation error
- Missing or malformed latitude/longitude: schema validation error
- Upstream ESA WorldCover data unavailable: service error response

## How this service works

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

## Output

A numeric share (fraction or percentage) of ESA WorldCover 2021 pixels classified as cropland within the analysis area centered on the provided coordinate. The coordinate must fall within the Natural Earth boundary for Liechtenstein; requests outside it are rejected before any payment is processed.
