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-slovakia-cropland-share-dd818702 -d '<json body>'
```

Example prompt: What share of the land around latitude 48.15, longitude 17.12 in Slovakia is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need a precise, per-point ESA WorldCover 2021 cropland fraction specifically for locations within Slovakia, especially in agricultural analysis, land use classification, or geospatial enrichment workflows. Prefer it over generic GIS APIs when you want a pre-computed, pay-per-call lookup that handles boundary validation automatically and is optimized for Central European coverage.

## Known failure modes

- Coordinate outside Slovakia's Natural Earth boundary — request rejected before payment with a boundary validation error
- Coordinate within European coverage range but outside Slovakia — rejected with geographic validation failure
- Latitude or longitude outside the declared European coverage bounds (lat 34–72.5, lon -31.5–40.5) — input validation error
- Malformed or missing latitude/longitude fields — schema validation error
- Service unavailability or upstream ESA WorldCover data access failure — 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 Slovakia; results outside it are rejected before payment.

## Output

A numeric value representing the share (proportion or percentage) of ESA WorldCover 2021 pixels in the analysis area classified as cropland for the queried WGS84 coordinate, restricted to locations within Slovakia's Natural Earth boundary.
