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-baltic-land-latvia-tree-cover-share-5a76deb6 -d '<json body>'
```

Example prompt: What fraction of the area around latitude 56.946 and longitude 24.105 in Latvia is classified as tree cover according to ESA WorldCover 2021 satellite data?

## When to prefer this

Choose this endpoint when you specifically need ESA WorldCover 2021 tree cover fraction data for a point location within Latvia. It is ideal for forestry analysis, environmental assessments, land use studies, or carbon accounting workflows focused on Latvian geography. Prefer this over generic land cover APIs when you need satellite-derived, pixel-level tree cover share with built-in Latvian boundary validation.

## Known failure modes

- Coordinate outside Latvia boundary — request rejected before payment
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing required latitude or longitude parameter — request error
- Location is within European bounds but outside Latvia — boundary validation rejection

## How this service works

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

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels classified as tree cover at the specified coordinate within Latvia. Returns an error or rejection if the coordinate falls outside the Latvian boundary.
