# HALOWERK Europe Land – Water & Wetland Share (Point, 60m)

> HALOWERK Europe Land – Water & Wetland Share (Point, 60m) is a paid API for AI agents from euroland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns the combined share of permanent water, herbaceous wetland, and mangrove ESA WorldCover 2021 classes within a 60-metre analysis grid around a single European coordinate.

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-water-wetland-share-point-60m-77d675ca -d '<json body>'
```

Example prompt: What's the combined water and wetland land cover share at latitude 51.9, longitude 4.5 in the Netherlands — use the 60-metre point analysis?

## When to prefer this

Choose this endpoint when you need a fast, point-based assessment of water and wetland land cover within a tight 60-metre radius around a specific European coordinate. It is ideal for site-level environmental screening, ecological risk flagging, or property-level hydrological characterisation where a small local grid is appropriate. Prefer the polygon or circular-buffer variants when you need coverage over a larger or custom-shaped area.

## Known failure modes

- Coordinates outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) return a validation error
- Malformed or missing latitude/longitude values result in a 400 bad request
- Areas with no ESA WorldCover data (e.g. data gaps) may return null or zero share
- Server errors or payment failures (x402) may cause 402 or 5xx responses

## How this service works

Combined share of permanent water, herbaceous wetland and mangrove classes. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.

## Output

A standardized numeric share (fraction or percentage) representing the combined proportion of permanent water, herbaceous wetland, and mangrove pixels within the 60-metre analysis grid centered on the supplied coordinate, derived from ESA WorldCover 2021 data and normalized across all 30 covered European countries.
