HALOWERK Central Land – CZ Terrain Aspect
x402
HALOWERK Central Land – CZ Terrain Aspect is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the circular direction (0–360°, clockwise from north) of the dominant surface gradient at a given coordinate within Czechia, derived from Copernicus DEM data.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Czechia; results outside it are rejected before payment.
Output
A single numeric value representing the circular direction (0–360°, clockwise from north) of the dominant surface gradient at the queried coordinate. Coordinates outside the Czechia boundary are rejected before any payment is charged.
Example use cases
Solar farm siting in Bohemia
“I'm evaluating a field near Kutná Hora at lat 49.95, lon 15.27 for a solar installation — what direction does the terrain slope face there?”
Vineyard microclimate assessment
“Can you tell me the slope aspect at lat 48.89, lon 16.65 in South Moravia? I need to know if the hillside faces south for a vineyard site evaluation.”
Hydrological flow modeling
“For my watershed model covering a point at lat 50.08, lon 13.45 in Czechia, what is the dominant surface gradient direction in degrees clockwise from north?”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/cz-aspectWhen to prefer
Choose this endpoint when you need the terrain aspect (slope-facing direction) specifically for a point within Czechia and want boundary pre-validation to avoid wasted payments. It is optimized for the Czech Republic coverage zone using Copernicus DEM GLO-30 data, making it more authoritative for CZ than a generic global terrain API. Prefer it for agriculture, solar siting, hydrology, or ecological analysis workflows scoped to Czechia.
Side effects
- Coordinate outside Czechia boundary — rejected with error before payment
- Latitude or longitude outside published European coverage bounds (lat 34–72.5, lon -31.5–40.5) — validation error
- Flat terrain with no dominant gradient may produce undefined or zero aspect
- Network timeout or service unavailability returns error response
- Malformed or missing coordinate fields return schema validation error
