HALOWERK Central Land – Surface Aspect (Slovenia)
x402
HALOWERK Central Land – Surface Aspect (Slovenia) 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 dominant terrain aspect (circular direction of the steepest surface gradient, clockwise from north) for a given WGS84 coordinate within Slovenia.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Slovenia; results outside it are rejected before payment.
Output
A numeric value representing the dominant surface aspect angle in degrees, measured clockwise from north (0°/360° = north, 90° = east, 180° = south, 270° = west). Coordinates outside the Slovenia boundary polygon are rejected before payment is processed.
Example use cases
Solar panel site suitability assessment
“I'm evaluating a plot in Slovenia at latitude 45.87, longitude 15.02 for solar panels — can you tell me which direction the slope faces so I know if it gets good sun exposure?”
Vineyard microclimate planning
“For a potential vineyard site at 46.34 latitude, 13.91 longitude in Slovenia, what's the terrain aspect? I need to know if the slope faces south for optimal grape growing conditions.”
Hiking trail slope orientation lookup
“Can you get me the aspect angle of the slope at coordinates 46.22 north, 14.67 east in Slovenia? I'm planning a trail route and need to know which way the hillside faces.”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/si-aspectWhen to prefer
Choose this endpoint when you need terrain aspect data specifically for a point location within Slovenia and want a pay-per-call model with pre-payment validation (no charge for out-of-bounds coordinates). It is ideal for precision land analysis workflows — viticulture, solar siting, ecological surveys, or trail planning — where slope orientation is a key variable. Prefer it over general DEM APIs when you need Slovenia-bounded validation and Copernicus GLO-30 derived data.
Side effects
- Coordinates outside Slovenia's Natural Earth boundary → rejected before charge, coordinate validation error returned
- Coordinates within European bounding box but outside Slovenia polygon → rejection with boundary error
- Flat terrain with no dominant gradient → may return null or special value indicating undefined aspect
- Malformed latitude/longitude values outside European coverage range → validation error
- Network or service timeout → no result returned
