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-baltic-land-estonia-cropland-share-12a4ac02 -d '<json body>'
```

Example prompt: What share of the land around latitude 58.37, longitude 26.73 in Estonia is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need a precise ESA WorldCover 2021 cropland fraction specifically for a point location within Estonia. It is preferable when you want boundary-validated results (coordinates outside Estonia are rejected before billing), when you need land cover data derived from a globally consistent 2021 satellite dataset, or when you are querying agricultural land use as part of a broader Baltic land analysis workflow alongside sibling endpoints for grassland, built-up area, soil properties, and terrain metrics.

## Known failure modes

- Coordinate outside Estonia's Natural Earth boundary — request rejected with validation error before payment
- Coordinate within European bounding box but outside Estonia — rejected at boundary check
- Missing or malformed latitude/longitude fields — validation error
- Latitude or longitude outside the declared European coverage range (34–72.5°N, -31.5–40.5°E) — rejected
- Service unavailable or upstream ESA WorldCover data issue — server 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 Estonia; results outside it are rejected before payment.

## Output

A numeric share (fraction or percentage) indicating how much of the ESA WorldCover 2021 pixels in the analysis area around the given Estonian coordinate are classified as cropland. Coordinates outside Estonia's Natural Earth boundary are rejected before payment is processed.
