## 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-norway-cropland-share-6c962027 -d '<json body>'
```

Example prompt: What share of the land around latitude 60.37, longitude 10.81 in Norway is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Use this endpoint when you need the precise ESA WorldCover 2021 cropland pixel share for a specific point in Norway, especially in workflows combining multiple land-cover or soil metrics from the HALOWERK Nordic Land suite. Prefer it over generic land-use APIs when Norway-validated, per-coordinate granularity and pay-per-call pricing matter.

## Known failure modes

- Coordinate outside Norway boundary — request rejected before payment with a boundary validation error
- Coordinate outside European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Invalid or missing latitude/longitude — input validation error
- Payment failure via x402 protocol — request not processed
- Upstream ESA WorldCover data unavailable — service error

## How this service works

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

## Output

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