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-water-wetland-share-bd6ee893 -d '<json body>'
```

Example prompt: What's the combined water, wetland, and mangrove land cover share at latitude 35.89, longitude 14.44 in Malta?

## When to prefer this

Choose this endpoint when you need a precise, pre-computed water and wetland land cover share specifically for a coordinate within Malta, and want a cost-effective single-call lookup ($0.003 USDC) backed by ESA WorldCover 2021 classification data. It is ideal for environmental assessments, site screening, flood risk analysis, or ecological baseline reporting focused on Malta. If you need other land cover classes (cropland, grassland, dominant class) or other soil/terrain metrics, use the sibling endpoints on the same platform.

## Known failure modes

- Coordinate outside Malta's Natural Earth boundary — request rejected before payment with a boundary validation error
- Coordinate outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) — schema validation failure
- Malformed or missing latitude/longitude — input validation error
- Service unavailable or timeout — HTTP 5xx error

## How this service works

Combined share of permanent water, herbaceous wetland and mangrove classes. The coordinate is validated against the Natural Earth boundary for Malta; results outside it are rejected before payment.

## Output

A numeric share (fraction or percentage) representing the combined ESA WorldCover 2021 area classified as permanent water, herbaceous wetland, and mangrove within the analysis window around the given coordinate. The coordinate is validated against Malta's Natural Earth boundary; points outside Malta are rejected before any payment is processed.
