## 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-finland-cropland-share-226afcfe -d '<json body>'
```

Example prompt: What share of the land around latitude 61.4 and longitude 23.7 in Finland is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you specifically need the ESA WorldCover 2021 cropland land-cover fraction for a point location within Finland. It is ideal for agricultural land assessments, site screening, environmental studies, or supply chain mapping requiring authoritative satellite-derived cropland proportion data. Pair with sibling endpoints on the same host for complementary soil and terrain metrics.

## Known failure modes

- Coordinate outside Finland boundary — rejected before payment even if within the broader European coverage box
- Latitude or longitude outside the declared European bounding box (lat 34–72.5, lon −31.5–40.5) — validation error
- Malformed or missing coordinate fields — schema validation error
- Service unavailability or network timeout — 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 Finland; 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 Finnish coordinate.
