HALOWERK Nordic Land – Iceland Surface Aspect
x402
HALOWERK Nordic Land – Iceland 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 2026-09-15).
Returns the circular direction (clockwise from north) of the dominant surface gradient for a given coordinate within Iceland.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Iceland; results outside it are rejected before payment.
Output
A numeric value representing the circular direction of the dominant surface gradient at the queried coordinate, measured in degrees clockwise from north (0–360°). Coordinates outside the Iceland boundary validated by Natural Earth are rejected before payment is processed.
Example use cases
Solar panel site suitability in Iceland
“I'm evaluating a site at latitude 65.3, longitude -18.7 in Iceland for solar panel installation — what direction does the slope face there? Give me the aspect clockwise from north so I can assess sun exposure.”
Glacier melt runoff modelling
“For a hydrology model I'm running, I need the surface aspect at latitude 64.1, longitude -21.3 in Iceland — which direction does the dominant slope gradient face, measured clockwise from north?”
Agricultural field orientation assessment
“I'm advising a farm at latitude 65.6, longitude -17.9 in Iceland on crop row orientation — what's the aspect angle of that land surface, clockwise from north?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/is-aspectWhen to prefer
Choose this endpoint when you need terrain aspect data specifically for coordinates within Iceland, and you require pre-payment boundary validation to avoid wasteful charges for out-of-bounds points. Prefer it over generic terrain APIs when working within the HALOWERK Nordic Land ecosystem alongside sibling endpoints for slope, soil, and wetland data.
Side effects
- Coordinate outside Iceland boundary: request rejected pre-payment with a boundary validation error
- Latitude or longitude outside published European coverage range: schema validation error
- Invalid coordinate format (non-numeric, null): input validation error
- Network timeout or service unavailability: HTTP 5xx error
