x402
HALOWERK Central Land – Austria Solar Orientation Index is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Computes a south-facing slope orientation index from terrain aspect and slope for a given coordinate within Austria.

How this service works
South-facing slope orientation index derived from aspect and slope. The coordinate is validated against the Natural Earth boundary for Austria; results outside it are rejected before payment.
Output
Returns a numeric south-facing slope orientation index derived from terrain aspect and slope data for the given Austrian coordinate. Coordinates outside Austria's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Solar farm site selection in Austria
“I'm evaluating land for a small solar installation near Salzburg — can you get the south-facing slope orientation index for latitude 47.81, longitude 13.04 so I know if the terrain gets good sun exposure?”
Agricultural land solar suitability check
“For a vineyard plot at 48.12 latitude, 15.63 longitude in Lower Austria, what is the slope orientation index toward the south? I want to know if it's well-positioned for sun.”
Terrain analysis for alpine building permit
“We're planning a mountain cabin near Innsbruck at 47.26 latitude, 11.40 longitude — can you compute the south-facing slope orientation index there to include in our planning documents?”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/at-solar-orientationWhen to prefer
Use this endpoint when you need a precise, index-based measure of how south-facing a slope is at a specific Austrian coordinate, particularly for solar energy assessments, agricultural suitability, or land development planning. It is Austria-specific and validates against official Natural Earth boundaries, making it more reliable than generic global terrain APIs for Austrian locations. Prefer this over elevation-only endpoints when solar orientation (aspect × slope composite) is the key variable.
Side effects
- Coordinate outside Austria's Natural Earth boundary — request rejected before payment, error returned
- Latitude or longitude out of the accepted European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Invalid or missing coordinate values — schema validation failure
- DEM or aspect data unavailable for the specific location — data gap error
