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-europe-land-tree-cover-share-point-60m-grid-20373389 -d '<json body>'
```

Example prompt: What's the tree cover share at latitude 51.5 longitude -0.1 in Europe, using the 60-metre local analysis grid from ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need a precise, point-based tree cover fraction derived from ESA WorldCover 2021 data for a specific European coordinate, particularly when a small 60-metre analysis window is appropriate (e.g., site-level assessment). Use sibling endpoints if you need a circular buffer (250m, 1km) or polygon-based evaluation, or if you need other land cover classes such as cropland, grassland, or wetland.

## Known failure modes

- Coordinate outside European coverage bounds (latitude 34–72.5, longitude −31.5–40.5) returns an error or empty result
- Invalid or missing latitude/longitude values cause a validation error
- Network timeout or service unavailability returns a 5xx error
- Coordinates on the exact boundary of coverage may produce edge-case results

## How this service works

Share of ESA WorldCover 2021 pixels classified as tree cover. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.

## Output

A standardized fractional value (share) representing the proportion of ESA WorldCover 2021 pixels within a 60-metre local analysis grid around the supplied coordinate that are classified as tree cover, expressed consistently across all 30 covered European countries.
