HALOWERK Nordic Land – Sweden Surface Aspect
x402
HALOWERK Nordic Land – Sweden Surface Aspect is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the circular direction of the dominant surface gradient (aspect) at a given coordinate within Sweden, measured clockwise from north in degrees.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Sweden; results outside it are rejected before payment.
Output
A numeric value representing the dominant surface gradient direction in degrees, measured clockwise from north (0–360°), for the specified coordinate within Sweden. Coordinates outside Sweden's Natural Earth boundary are rejected before any charge is made.
Example use cases
Solar panel siting for Swedish farm
“I'm evaluating a field in Sweden near latitude 57.7, longitude 14.9 — can you tell me what direction the terrain faces there so I can assess solar exposure for panel installation?”
Forest harvest slope orientation
“For a logging site in northern Sweden at latitude 65.1, longitude 17.3, I need to know which direction the dominant slope faces — clockwise from north please.”
Hydrological flow direction modelling
“Give me the surface aspect at latitude 59.9, longitude 16.5 in Sweden so I can determine the likely runoff direction for a watershed model.”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-aspectWhen to prefer
Choose this endpoint when you need terrain aspect (slope-facing direction) specifically for coordinates within Sweden. It is pre-validated against Sweden's boundary so charges are only incurred for valid in-country queries. Prefer it over generic DEM APIs when working in a Nordic/Scandinavian geospatial pipeline that already uses HALOWERK's suite of soil and terrain endpoints.
Side effects
- Coordinate outside Sweden's Natural Earth boundary — rejected before payment with a validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — rejected with input validation error
- No-data areas (e.g. flat terrain with undefined aspect) may return null or a special code
- Network timeout or service unavailability returns a 5xx error
