HALOWERK Central Land – Slovakia Aspect Direction
x402
HALOWERK Central Land – Slovakia Aspect Direction 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 Slovakia, derived from Copernicus DEM data.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Slovakia; results outside it are rejected before payment.
Output
A numeric value representing the circular aspect direction in degrees (0–360, clockwise from north) of the dominant surface gradient at the queried coordinate. Coordinates outside Slovakia's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Solar farm site orientation check
“I'm evaluating a plot in Slovakia near latitude 48.6, longitude 17.8 for solar panels — can you tell me which direction the slope faces, in degrees clockwise from north?”
Agricultural drainage planning
“For my field in Slovakia at coordinates 49.1 latitude, 20.2 longitude, what's the dominant downslope direction? I need the aspect angle to plan drainage.”
Hiking trail terrain profiling
“I'm mapping a trail in the Slovak Tatras near lat 49.18, lon 20.05 — can you tell me what direction the slope faces at that point so I know the sun exposure?”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/sk-aspectWhen to prefer
Use this endpoint when you specifically need the aspect (slope-facing direction) for a point in Slovakia derived from Copernicus DEM GLO-30 data. It is preferable when you need Slovakia-specific boundary validation before incurring cost, and when aspect is the primary terrain attribute needed (as opposed to elevation, slope magnitude, or land cover class, which are separate sibling endpoints).
Side effects
- Coordinate outside Slovakia boundary: request rejected with an error before payment is processed
- Coordinate within European bounding box but outside Slovakia polygon: validation failure returned
- Flat terrain with no dominant gradient may yield undefined or unreliable aspect
- Malformed or out-of-range latitude/longitude values return a validation error
- Network or service timeout
