Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-malta-cropland-share-24ed3089 -d '<json body>'
```

Example prompt: What share of the land around latitude 35.89, longitude 14.44 in Malta is classified as cropland according to ESA WorldCover satellite data?

## When to prefer this

Use this endpoint when you need pixel-level ESA WorldCover 2021 cropland classification specifically for coordinates within Malta. It is ideal for agricultural land assessments, environmental impact studies, or land use analysis constrained to Malta, and is preferable over generic land cover APIs when you need authoritative satellite-derived data validated against Malta's official boundary at low per-call cost.

## Known failure modes

- Coordinate outside Malta's Natural Earth boundary — rejected before payment with a validation error
- Latitude or longitude outside the European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Non-numeric or malformed coordinate values — input validation error
- Coordinate inside coverage bounds but in sea or non-land area — may return zero or error

## How this service works

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

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels in the analysis area around the given coordinate that are classified as cropland, validated against Malta's Natural Earth boundary.
