HALOWERK Baltic Land – Surface Aspect (Germany)
x402
HALOWERK Baltic Land – Surface Aspect (Germany) is a paid API for AI agents from baltikum.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 at a given WGS84 coordinate within Germany.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Germany; results outside it are rejected before payment.
Output
A numeric value representing the circular direction (in degrees, 0–360, clockwise from north) of the dominant surface gradient at the queried coordinate. A value of 0/360 indicates north-facing, 90 east-facing, 180 south-facing, 270 west-facing. Coordinates outside Germany's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Solar farm site orientation check
“I'm evaluating a potential solar panel site near Munich at 48.1°N, 11.6°E — can you tell me which direction the terrain faces so I know if it gets good southern exposure?”
Agricultural field drainage planning
“For our farm plot at 52.5°N, 13.4°E in Brandenburg, what direction does the land surface slope toward? We need the aspect angle to plan water runoff channels.”
Hiking trail slope orientation
“We're planning a north-facing winter hiking trail in the Harz mountains — can you check the terrain aspect at 51.7°N, 10.7°E to confirm which way the slope faces?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/de-aspectWhen to prefer
Choose this endpoint when you need a precise terrain aspect (slope direction) value for a specific point within Germany, especially for applications like solar site assessment, agricultural drainage planning, ecological habitat modeling, or hillside orientation analysis. It is distinct from slope magnitude endpoints and is validated specifically against Germany's boundary, making it reliable for German land-surface workflows.
Side effects
- Coordinate outside Germany's Natural Earth boundary — request rejected before payment, error returned indicating out-of-bounds
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Flat or near-flat terrain may return undefined or noisy aspect values
- Missing or malformed latitude/longitude — schema validation error
- Network or service unavailability — HTTP 5xx error
