How this service works
Share of ESA WorldCover 2021 pixels classified as built-up. The coordinate is validated against the Natural Earth boundary for Romania; results outside it are rejected before payment.
Output
A numeric value representing the fraction (share) of ESA WorldCover 2021 pixels classified as built-up at the requested coordinate within Romania, validated against the Natural Earth Romania boundary before returning results.
Example use cases
Urban density check for site selection
“I'm evaluating a plot at 46.77, 23.59 in Romania — can you tell me what fraction of that area is classified as built-up land so I can understand how urbanized the surroundings are?”
Environmental impact assessment
“For our environmental report, I need the built-up land cover share at coordinates 44.93 latitude, 26.03 longitude in Romania — pull that from ESA WorldCover data please.”
Rural vs urban classification for insurance risk
“Can you check how built-up the area is at 45.75 latitude, 21.23 longitude in Romania? We need the WorldCover built-up pixel share to classify this property's urban exposure.”

Endpoint
POSThttps://ostland.halowerk.com/v1/ro-built-up-shareWhen to prefer
Use this endpoint when you specifically need the ESA WorldCover 2021 built-up land cover share for a point in Romania validated against official boundaries. Prefer it over generic geospatial APIs when you need authoritative satellite-derived urban classification at pixel resolution for Romanian territory, and when the x402 micropayment model is acceptable for per-call pricing.
Side effects
- Coordinate outside Romania boundary — rejected before payment with an error indicating the point falls outside the validated Natural Earth boundary
- Coordinate outside the broader European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Missing or malformed latitude/longitude input — request validation failure
- No WorldCover data available for the exact point — may return null or zero share
- Service unavailability or upstream ESA data issue — HTTP 5xx error
