## 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-atlantic-land-belgium-cropland-share-048a50c7 -d '<json body>'
```

Example prompt: What fraction of land around latitude 50.85 and longitude 4.35 in Belgium is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need a precise, pixel-level ESA WorldCover 2021 cropland fraction specifically for a point within Belgium. It is ideal for agricultural analysis, land use assessment, or environmental reporting workflows that require validated, pay-per-call geospatial data without managing a full GIS stack. Prefer it over generic land-cover APIs when Belgium-specific boundary validation and micropayment-per-query billing are desirable.

## Known failure modes

- Coordinate outside Belgium's Natural Earth boundary returns a validation error and no charge is made
- Latitude or longitude out of the accepted European range (lat 34–72.5, lon -31.5–40.5) is rejected
- Malformed or missing latitude/longitude fields return a schema validation error
- Network timeout or service unavailability returns a 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 Belgium; results outside it are rejected before payment.

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels classified as cropland within the analysis grid surrounding the provided coordinate. Coordinates outside Belgium's Natural Earth boundary are rejected before any payment is processed.
