HALOWERK Atlantic Land – France Aspect Direction
x402
HALOWERK Atlantic Land – France Aspect Direction is a paid API for AI agents from atlantikland.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 aspect (slope-facing direction), clockwise from north, for a given coordinate within France.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for France; results outside it are rejected before payment.
Output
A numeric value representing the circular direction (in degrees, clockwise from north) of the dominant surface slope gradient at the queried location within France. Coordinates outside the France boundary are rejected before any charge is applied.
Example use cases
Solar panel site suitability in France
“I'm evaluating a site in southern France at latitude 43.6, longitude 3.9 — can you tell me which direction the land faces so I know if it gets good sun exposure?”
Vineyard slope orientation assessment
“For my vineyard plot near Bordeaux at latitude 44.9, longitude -0.5, what's the dominant slope-facing direction? I need the aspect angle clockwise from north.”
Runoff and erosion risk analysis
“I need the terrain aspect direction at latitude 47.2, longitude 5.3 in France to figure out which way water would flow across this parcel for an erosion risk model.”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/fr-aspectWhen to prefer
Use this endpoint when you need the terrain aspect (slope-facing direction) specifically for a point within France, and you want a validated, boundary-checked result with pay-per-call pricing. Prefer this over generic elevation or slope APIs when you need the circular directional component of terrain orientation (not just slope magnitude) and when France coverage with boundary validation is required.
Side effects
- Coordinate outside France boundary — request rejected before payment, returning a validation error
- Latitude or longitude outside the allowed European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Invalid coordinate format or missing required fields — returns input validation error
- Service unavailable or upstream DEM data issue — may return a 5xx error
