x402
HALOWERK Eastern Land – Hungary Aspect Direction is a paid API for AI agents from ostland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the circular compass direction (clockwise from north) of the dominant surface gradient for a given coordinate within Hungary.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Hungary; results outside it are rejected before payment.
Output
A numeric value representing the circular compass bearing (in degrees, clockwise from north) of the dominant surface gradient at the requested coordinate. Coordinates outside the Hungary boundary are rejected before any payment is charged.
Example use cases
Solar panel site suitability assessment
“I'm evaluating a plot in Hungary at lat 47.2, lon 18.9 — can you tell me which direction the slope faces there? I need the aspect angle clockwise from north to assess south-facing solar exposure.”
Agricultural drainage planning
“For our farm field in Hungary at coordinates 47.85 latitude, 21.4 longitude, what's the dominant slope orientation? I want to know which compass direction the terrain gradient points so we can plan drainage.”
Hiking trail slope-facing characterization
“Can you get the terrain aspect at lat 47.5, lon 17.6 in Hungary for a trail planning project? I need to know the clockwise-from-north direction the slope faces at that point.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hu-aspectWhen to prefer
Use this endpoint when you need the terrain aspect (slope-facing direction) specifically for a point within Hungary and want boundary validation enforced before payment. Prefer this over general-purpose DEM APIs when working within the Hungarian national boundary, especially in workflows combining multiple HALOWERK Eastern Land terrain metrics (slope, ruggedness, tree cover, soil) for the same coordinate.
Side effects
- Coordinate outside Hungary boundary — request rejected before payment, no result returned
- Coordinate within European bounding box but outside Hungary polygon — boundary validation fails
- Invalid or missing latitude/longitude values — input schema validation error
- Latitude/longitude at flat terrain with no dominant gradient — result may be undefined or edge-case value
- Network or payment processing failure — no result returned
