How this service works
Combined share of permanent water, herbaceous wetland and mangrove classes. The coordinate is validated against the Natural Earth boundary for Portugal; results outside it are rejected before payment.
Output
A numeric share (fraction or percentage) representing the combined proportion of ESA WorldCover 2021 pixels classified as permanent water, herbaceous wetland, or mangrove within the analysis area around the given coordinate in Portugal. The coordinate is validated against the Natural Earth Portugal boundary before the result is returned; coordinates outside Portugal are rejected.
Example use cases
Wetland exposure check for Portuguese farmland
“I'm evaluating a plot near latitude 37.01, longitude -8.02 in Portugal — what fraction of the surrounding land is covered by water, wetland, or mangrove according to ESA WorldCover data?”
Environmental risk screening for construction site
“We're planning a development near lat 41.15, lon -8.62 in Portugal. Can you tell me the combined share of permanent water, herbaceous wetland, and mangrove in that area so we can assess flood and wetland risk?”
Biodiversity baseline for conservation report
“For a conservation report I need the water and wetland land-cover share at coordinates 39.45 latitude, -8.78 longitude in Portugal — please pull the ESA WorldCover figure for permanent water, wetland, and mangrove combined.”

Endpoint
POSThttps://suedland.halowerk.com/v1/pt-water-wetland-shareWhen to prefer
Choose this endpoint when you need ESA WorldCover 2021-based water and wetland land-cover fraction specifically for a point location within Portugal. It is ideal for geospatial enrichment workflows, environmental due diligence, agricultural site assessment, or conservation analysis where wetland and water exposure is a key variable and Portugal boundary validation is required. Prefer this over general land-cover APIs when you need the combined permanent-water + wetland + mangrove share as a single metric for Portuguese coordinates.
Side effects
- Coordinate outside Portugal boundary: rejected before processing, returns an error indicating the point is outside the valid coverage area
- Latitude or longitude outside European coverage bounds (lat 34–72.5, lon −31.5–40.5): schema validation failure
- Malformed or missing coordinate fields: request rejected with input validation error
- Payment failure or insufficient USDC balance: x402 payment-required response before data is returned
