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-nordic-land-sweden-cropland-share-80865b18 -d '<json body>'
```

Example prompt: What share of the land around latitude 59.3 and longitude 17.8 in Sweden is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Use this endpoint when you need a precise cropland coverage fraction for a specific point location within Sweden, derived from ESA WorldCover 2021 satellite data. Prefer it over generic land-cover APIs when you specifically need Sweden-validated results and the cropland class share rather than a dominant class label (use the sibling dominant-class endpoint for that). Best suited for agricultural analysis, site assessment, environmental reporting, or land investment workflows targeting Swedish geography.

## Known failure modes

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

## Output

A numeric value representing the fraction (share) of ESA WorldCover 2021 pixels within the analysis area around the given coordinate that are classified as cropland, constrained to locations within Sweden's Natural Earth boundary.
