HALOWERK Central Land – Surface Aspect (Austria)
x402
HALOWERK Central Land – Surface Aspect (Austria) 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).
Returns the circular direction (in degrees, clockwise from north) of the dominant surface gradient for a given coordinate within Austria.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Austria; results outside it are rejected before payment.
Output
A numeric value representing the aspect angle in degrees (0–360), measured clockwise from north, indicating the direction the dominant surface gradient faces at the queried coordinate. Returns an error if the coordinate falls outside Austria's Natural Earth boundary.
Example use cases
Alpine solar panel siting
“I'm evaluating a site near Innsbruck at 47.26° N, 11.39° E — can you tell me which direction the hillside faces so I know if it gets good south-facing sun exposure?”
Ski run orientation assessment
“For a point on a potential ski run at latitude 47.51, longitude 12.64 in Austria, what is the surface aspect angle clockwise from north?”
Hydrological flow direction lookup
“I need to know the dominant slope direction at coordinates 48.12 N, 15.45 E in Austria for a drainage modeling project — what's the aspect there?”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/at-aspectWhen to prefer
Choose this endpoint when you need terrain aspect (slope-facing direction) specifically for a coordinate within Austria, validated against official Natural Earth boundaries, at low per-call cost. Prefer this over general-purpose DEM APIs when you want a pre-validated, Austria-scoped result without managing boundary checks yourself. It is part of a broader land surface analytics suite on the same host, making it easy to combine with elevation, slope, and soil data for the same point.
Side effects
- Coordinate outside Austria boundary — rejected before payment, returns validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Ambiguous or missing coordinate fields — 400 bad request
- Service unavailable or upstream DEM data error — 5xx response
