## 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-france-cropland-share-ba2a2748 -d '<json body>'
```

Example prompt: What share of the land around latitude 47.3, longitude 2.1 in France is classified as cropland according to ESA WorldCover?

## When to prefer this

Use this endpoint when you need ESA WorldCover 2021 cropland land-cover fractions specifically for locations within France. It is preferable when you need a fast, per-point lookup with boundary-validated results and are working within an x402 micropayment workflow. For other land cover classes (grassland, built-up) or other countries, use the corresponding sibling endpoints on the same platform.

## Known failure modes

- Coordinate outside France boundary – request rejected before processing and payment
- Latitude or longitude outside published European coverage range (lat 34–72.5, lon -31.5–40.5) – validation error
- Malformed or missing latitude/longitude fields – schema validation error
- Payment failure via x402 protocol – call not executed

## How this service works

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

## Output

A numeric share (fraction or percentage) representing how much of the ESA WorldCover 2021 analysis grid pixels centered on the queried coordinate are classified as cropland. The coordinate is validated against France's Natural Earth boundary before the result is returned; coordinates outside France are rejected.
