## 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-eastern-land-cyprus-cropland-share-b98668c8 -d '<json body>'
```

Example prompt: What share of ESA WorldCover 2021 pixels around latitude 35.1264, longitude 33.4299 in Cyprus are classified as cropland?

## When to prefer this

Use this endpoint when you specifically need ESA WorldCover 2021 cropland land-cover fraction for a point location within Cyprus. It is purpose-built for Cyprus with boundary validation built in, making it more reliable than generic land-cover APIs for this region. Prefer it when you need a cheap, fast, per-coordinate cropland share without running your own raster analysis pipeline.

## Known failure modes

- Coordinate outside Cyprus boundary — request rejected before payment with a validation error
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed JSON body — 400-level error
- Payment failure via x402 protocol — request not processed
- Network timeout — transient error requiring retry

## How this service works

Share of ESA WorldCover 2021 pixels classified as cropland. The coordinate is validated against the Natural Earth boundary for Cyprus; 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 given coordinate. Coordinates outside the Cyprus boundary are rejected before any computation or payment is processed.
