How this service works
Share of ESA WorldCover 2021 pixels classified as built-up. The coordinate is validated against the Natural Earth boundary for Hungary; results outside it are rejected before payment.
Output
A numeric share (fraction or percentage) representing the proportion of ESA WorldCover 2021 pixels in the analysis grid around the queried coordinate that are classified as built-up/developed land. Coordinates outside Hungary's Natural Earth boundary are rejected before any payment is charged.
Example use cases
Urban density check for site selection
“We're evaluating a site at latitude 47.6, longitude 17.9 in Hungary — can you tell me what fraction of the surrounding area is classified as built-up according to ESA WorldCover 2021?”
Rural vs urban classification for insurance
“I need to know how urbanized the area around 46.25° N, 20.15° E in Hungary is — what's the built-up land share there?”
Land use analysis for agricultural planning
“For a parcel at 47.1° N, 18.4° E inside Hungary, what percentage of nearby pixels are classified as built-up rather than open land?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hu-built-up-shareWhen to prefer
Use this endpoint when you need a precise, satellite-derived built-up land cover fraction for a specific point inside Hungary, sourced from ESA WorldCover 2021. Prefer it over generic geocoding or population-density APIs when you need pixel-level land classification rather than administrative or census data. Its pre-payment boundary validation avoids wasted charges for out-of-scope coordinates.
Side effects
- Coordinate outside Hungary's Natural Earth boundary — request rejected with no charge
- Coordinate outside the broader European coverage bounds (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing latitude/longitude fields — schema validation error
- Payment failure — x402 payment not completed, request not processed
