## 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-southern-land-es-cropland-share-c43d10e4 -d '<json body>'
```

Example prompt: What share of the land around latitude 40.4168, longitude -3.7038 in Spain is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Use this endpoint when you need ESA WorldCover 2021 cropland coverage statistics for a specific point location within Spain. It is the right choice when you need a fast, per-call lookup of agricultural land share with built-in boundary validation for Spain, paid per query via x402. Prefer this over generic GIS queries when you need a standardized, satellite-derived land cover metric without setting up your own raster processing pipeline.

## Known failure modes

- Coordinate outside Spain boundary — rejected before payment as coordinate fails Natural Earth Spain validation
- Coordinate outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Invalid or missing latitude/longitude — input validation error
- Payment failure — x402 payment not completed, no result returned

## How this service works

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

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels within the analysis area classified as cropland, for the validated Spanish coordinate.
