HALOWERK Baltic Land – Surface Aspect (Lithuania)
x402
HALOWERK Baltic Land – Surface Aspect (Lithuania) is a paid API for AI agents from baltikum.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the dominant surface gradient direction (aspect angle, clockwise from north) for a given coordinate within Lithuania's boundary.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Lithuania; results outside it are rejected before payment.
Output
A numeric value representing the circular direction of the dominant surface gradient at the queried coordinate, expressed in degrees clockwise from north (0–360°). Coordinates outside Lithuania's Natural Earth boundary are rejected before any charge is made.
Example use cases
Solar farm site orientation assessment
“I'm evaluating a potential solar farm site near Kaunas — can you tell me the dominant terrain slope direction at 54.8985° N, 23.9036° E in Lithuania? I need to know if the land faces south.”
Agricultural drainage planning
“For a field I'm looking at in rural Lithuania at 55.1000° N, 24.3500° E, what direction does the surface slope? I need the aspect to plan how water will drain across the terrain.”
Hiking trail slope orientation check
“I'm planning a trail near Vilnius at 54.7200° N, 25.1500° E in Lithuania — which compass direction does the slope face there? I want to know the dominant aspect angle from north.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/lt-aspectWhen to prefer
Use this endpoint when you need the compass-bearing direction of the dominant terrain slope for a specific point in Lithuania. It is ideal for site suitability analysis (solar, agriculture, construction), hydrological modeling, ecological habitat assessment, or any workflow requiring terrain orientation within Lithuania specifically. Prefer this over generic elevation or slope-magnitude endpoints when directionality (aspect) is the key variable, and prefer it over general European terrain APIs when you need Lithuania-specific boundary validation built into the service.
Side effects
- Coordinate outside Lithuania's Natural Earth boundary — request rejected before payment, returns boundary validation error
- Latitude or longitude outside the broader European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- No terrain data available for the given point — may return null or no-data response
- Malformed request body — missing required latitude or longitude fields
- Payment failure via x402 protocol — request not processed
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| latitude | number | WGS84 latitude inside the published European coverage. |
| longitude | number | WGS84 longitude inside the published European coverage. |
