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-central-land-slovenia-tree-cover-share-2b7f5cdf -d '<json body>'
```

Example prompt: What share of the land around latitude 46.12, longitude 14.30 in Slovenia is classified as tree cover according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need a precise, satellite-derived tree cover fraction for a specific point location within Slovenia, sourced from ESA WorldCover 2021. It is ideal for environmental assessments, land use analysis, forestry planning, or biodiversity screening workflows that require per-coordinate land cover data rather than country-level aggregates. Prefer it over generic land cover APIs when Slovenia-specific boundary validation and ESA WorldCover 2021 classification accuracy matter.

## Known failure modes

- Coordinate outside Slovenia's Natural Earth boundary — request rejected before payment is processed
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Invalid or missing coordinate fields — schema validation failure
- Payment failure via x402 protocol — call not executed
- Service unavailable or timeout from upstream ESA WorldCover data source

## How this service works

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

## Output

A numeric share (proportion or percentage) of ESA WorldCover 2021 pixels in the analysis area around the given coordinate that are classified as tree cover, valid only for coordinates within Slovenia's Natural Earth boundary.
