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-nordic-land-finland-water-wetland-share-714ff41c -d '<json body>'
```

Example prompt: What's the combined share of permanent water, herbaceous wetland, and mangrove cover at latitude 61.48, longitude 23.76 in Finland?

## When to prefer this

Choose this endpoint when you need authoritative water and wetland land-cover fractions specifically for locations within Finland, backed by validated Natural Earth boundary checks. Prefer it over generic land-cover APIs when you need Finland-specific validation guarantees and a combined water+wetland+mangrove metric in a single call.

## Known failure modes

- Coordinate outside Finland's Natural Earth boundary — request rejected, no charge
- Latitude or longitude outside the accepted European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — schema validation error
- No land-cover data available for the queried grid cell — empty or null result

## How this service works

Combined share of permanent water, herbaceous wetland and mangrove classes. The coordinate is validated against the Natural Earth boundary for Finland; results outside it are rejected before payment.

## Output

A numeric value representing the combined fractional share (likely 0–1 or as a percentage) of permanent water bodies, herbaceous wetland, and mangrove land-cover classes within the analysis area surrounding the given Finnish coordinate. Coordinates outside Finland's Natural Earth boundary are rejected before any charge is incurred.
