How this service works
Share of ESA WorldCover 2021 pixels classified as built-up. The coordinate is validated against the Natural Earth boundary for Portugal; results outside it are rejected before payment.
Output
A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels classified as built-up within the analysis area around the provided Portuguese coordinate. Coordinates outside the Natural Earth boundary for Portugal are rejected before any payment is charged.
Example use cases
Urban density check for site selection
“I'm evaluating a potential warehouse site near latitude 41.15 longitude -8.61 in Portugal — can you tell me what fraction of the surrounding area is built-up according to ESA WorldCover 2021?”
Rural property urbanization assessment
“We're buying agricultural land at coordinates 37.85 latitude -8.20 longitude in Portugal — how much of the pixel area around that spot is classified as built-up?”
Urban sprawl monitoring for a Portuguese municipality
“Can you pull the built-up pixel share for the coordinate at latitude 38.52 longitude -8.89 in Portugal so I can track how urbanized that area has become?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-built-up-shareWhen to prefer
Choose this endpoint when you need satellite-derived, pixel-level built-up land cover statistics for a specific point in Portugal from the authoritative ESA WorldCover 2021 dataset, especially when boundary validation and per-call micropayment pricing are acceptable. Prefer it over generic land cover APIs when Portugal-specific boundary enforcement and WorldCover 2021 provenance matter.
Side effects
- Coordinate outside Portugal's Natural Earth boundary — request rejected before payment
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing latitude/longitude fields — schema validation failure
- Payment failure via x402 protocol — request not processed
