HALOWERK Baltic Land – Surface Aspect (Poland)
x402
HALOWERK Baltic Land – Surface Aspect (Poland) is a paid API for AI agents from baltikum.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the circular direction of the dominant surface gradient (aspect, clockwise from north) for a given coordinate within Poland'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 Poland; results outside it are rejected before payment.
Output
A numeric value representing the circular direction (in degrees, clockwise from north) of the dominant surface gradient at the queried point. Coordinates outside Poland's Natural Earth boundary are rejected before any payment is charged.
Example use cases
Slope orientation for solar panel siting
“I'm planning a solar farm near Kraków — can you tell me the aspect direction of the slope at latitude 50.06, longitude 19.94 in Poland so I know if it faces south?”
Terrain analysis for agricultural drainage
“I need to understand which direction water flows on the hillside at latitude 54.35, longitude 18.65 in northern Poland — what's the surface gradient aspect there?”
Hiking trail slope orientation check
“For a trail waypoint at latitude 49.25, longitude 19.98 in the Tatra foothills of Poland, what direction does the slope face — clockwise from north?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-aspectWhen to prefer
Choose this endpoint when you need terrain aspect data specifically for locations in Poland and want pre-validated boundary checking (so out-of-bounds requests don't incur charges). Prefer it over general-purpose DEM APIs when working within the HALOWERK Baltic Land suite for consistent spatial resolution and payment-gated access.
Side effects
- Coordinate outside Poland boundary — request rejected before payment, returns error indicating location is out of coverage
- Latitude or longitude outside the published European range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Missing or malformed coordinate fields — returns 400-level error
- No data available for the exact cell — rare edge cases at border regions or data voids
