How this service works
Combined share of permanent water, herbaceous wetland and mangrove classes. The coordinate is validated against the Natural Earth boundary for Hungary; results outside it are rejected before payment.
Output
A numeric fraction (0–1 or percentage) representing the combined share of ESA WorldCover 2021 pixels classified as permanent water, herbaceous wetland, and mangrove within the analysis grid cell surrounding the requested coordinate. Requests outside the Hungary boundary are rejected before any payment is processed.
Example use cases
Agricultural land suitability screening
“Before we consider buying that parcel near Győr, can you check the combined water and wetland land-cover share at latitude 47.68, longitude 17.63 in Hungary? I want to know how much of the area is classified as water or wetland.”
Environmental impact pre-assessment
“I need the permanent water plus wetland coverage fraction for a construction site in Hungary at lat 46.9, lon 20.1 — can you look that up so I can include it in the environmental pre-assessment report?”
Ecological corridor mapping
“Can you pull the water and wetland share for several points along the Tisza River in Hungary, starting with latitude 48.0, longitude 21.4? I'm mapping wetland connectivity for a biodiversity project.”

Endpoint
POSThttps://ostland.halowerk.com/v1/hu-water-wetland-shareWhen to prefer
Choose this endpoint when you need ESA WorldCover 2021-derived water and wetland coverage statistics specifically for a point location within Hungary, particularly when boundary-validated results and micropayment-per-call pricing (x402) are acceptable. Prefer it over generic land-cover APIs when you need the combined permanent water + herbaceous wetland + mangrove share as a single metric and when Hungary-scoped validation is a feature rather than a limitation.
Side effects
- Coordinate outside Hungary boundary: request rejected with validation error before payment
- Latitude or longitude out of European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation failure
- Invalid or malformed coordinate values: 400-level error
- Network or service downtime: timeout or 5xx error
- Payment failure via x402 protocol: request not processed
