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-netherlands-tree-cover-share-bf7a6066 -d '<json body>'
```

Example prompt: What share of the land at latitude 52.37 and longitude 4.89 in the Netherlands is classified as tree cover according to the ESA WorldCover 2021 data?

## When to prefer this

Use this endpoint when you need a precise, satellite-derived tree cover fraction for a specific point location within the Netherlands, sourced from the authoritative ESA WorldCover 2021 dataset. Prefer it over generic land cover APIs when Netherlands-specific boundary validation and per-call micropayment pricing are acceptable, and when you need a single-point lookup rather than bulk raster processing.

## Known failure modes

- Coordinate outside Netherlands boundary — request rejected before payment, returns validation error
- Coordinate within European coverage bounds but outside Netherlands — rejected by Natural Earth boundary check
- Missing or malformed latitude/longitude — returns schema validation error
- Coordinate at sea or on a border edge — may be rejected depending on boundary polygon precision

## How this service works

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

## Output

A numeric share (fraction or percentage) of ESA WorldCover 2021 pixels classified as tree cover within the analysis grid around the provided coordinate in the Netherlands. Coordinates outside the Netherlands boundary are rejected before any charge is incurred.
