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-cropland-share-iceland-009ae231 -d '<json body>'
```

Example prompt: What share of land around latitude 64.1, longitude -21.9 in Iceland is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need a satellite-derived, pixel-level cropland share metric specifically for a point in Iceland, sourced from the authoritative ESA WorldCover 2021 dataset. It is ideal for land-use analysis, agricultural assessments, or due-diligence workflows that require reliable boundary enforcement (non-Iceland coordinates are rejected before billing). Prefer it over generic land-cover APIs when Iceland-specific validation and ESA WorldCover classification fidelity are required.

## Known failure modes

- Coordinate outside Iceland boundary — rejected before payment with a boundary validation error
- Coordinate outside the broader European coverage bounding box (lat 34–72.5, lon -31.5–40.5) — rejected as invalid
- Malformed or missing latitude/longitude fields — returns a schema validation error
- Service unavailability or upstream ESA WorldCover data access failure — HTTP 5xx response

## How this service works

Share of ESA WorldCover 2021 pixels classified as cropland. The coordinate is validated against the Natural Earth boundary for Iceland; results outside it are rejected before payment.

## Output

A numeric share (fraction or percentage) of ESA WorldCover 2021 pixels in the analysis area around the given coordinate that are classified as cropland. Coordinates outside the Iceland boundary are rejected before any charge is applied.
