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-czechia-cropland-share-d5340493 -d '<json body>'
```

Example prompt: What share of the land around latitude 49.74, longitude 13.38 in Czechia is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Use this endpoint when you need ESA WorldCover 2021 cropland share specifically for a coordinate within Czechia. It is purpose-built for Czech agricultural land cover queries with built-in boundary validation, making it more reliable than general-purpose land cover APIs that may not validate coordinates or may source from different datasets. Prefer this over grassland-share or soil endpoints when cropland classification is the specific metric needed.

## Known failure modes

- Coordinate outside Czechia boundary — rejected before payment with a geographic validation error
- Latitude or longitude out of published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed request body missing required latitude or longitude fields — HTTP 400 error
- Service unavailable or upstream data access failure — HTTP 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 Czechia; results outside it are rejected before payment.

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels at the given coordinate classified as cropland, restricted to coordinates within the Natural Earth boundary of Czechia.
