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-atlantic-land-luxembourg-tree-cover-share-ae8ebca6 -d '<json body>'
```

Example prompt: What share of the land around latitude 49.6116, longitude 6.1319 in Luxembourg is classified as tree cover according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need ESA WorldCover 2021-derived tree cover fraction for a specific point location within Luxembourg. It is the right choice for land assessment, environmental baseline reporting, forestry analysis, or green infrastructure mapping at the parcel or coordinate level inside Luxembourg. Prefer it over generic GIS platforms when you need a direct, pay-per-call API with no subscription overhead and integrated boundary validation.

## Known failure modes

- Coordinate outside Luxembourg boundary — request is rejected before payment with a boundary validation error
- Coordinate outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) — rejected with schema validation error
- Malformed or missing latitude/longitude fields — returns input validation error
- Service unavailable or upstream ESA data issue — returns 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 Luxembourg; results outside it are rejected before payment.

## Output

A numeric value representing the fraction (share) of ESA WorldCover 2021 pixels classified as tree cover within the analysis grid centred on the provided coordinate. The coordinate is validated against the Natural Earth boundary for Luxembourg; out-of-boundary coordinates are rejected before any charge is applied.
