## 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-tree-cover-share-cf59d343 -d '<json body>'
```

Example prompt: What's the tree cover share at latitude 35.9042, longitude 14.4189 in Malta according to ESA WorldCover 2021?

## When to prefer this

Use this endpoint when you specifically need ESA WorldCover 2021 tree cover pixel share for a location within Malta. It is part of a broader suite of land cover and soil endpoints for Malta and other European locations on the HALOWERK Southern Land platform. Prefer this over generic GIS APIs when you need pay-per-call simplicity with no setup, and when the target coordinate is confirmed to be within Malta. If you need cropland or grassland share instead, 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 within the European coverage bounding box but outside Malta — rejected at boundary check
- Missing or invalid latitude/longitude values — schema validation error
- Coordinate on the boundary edge causing ambiguous inclusion — may be rejected
- Service unavailability returning 5xx error

## How this service works

Share of ESA WorldCover 2021 pixels classified as tree cover. 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 proportion of ESA WorldCover 2021 pixels classified as tree cover within the analysis area centered on the provided coordinate. The coordinate must fall within Malta's Natural Earth boundary or the request is rejected before payment.
