x402
HALOWERK Europe Land – Aspect (250m Buffer) is a paid API for AI agents from euroland.halowerk.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-15).
Returns the circular direction of the dominant surface gradient (aspect), clockwise from north, computed over a 250-metre neighbourhood around a European coordinate.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The service evaluates a circular 250 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
A single numeric value representing the circular direction of the dominant surface gradient in degrees, measured clockwise from north (0–360°), derived from a 250-metre circular neighbourhood analysis around the supplied WGS84 coordinate. Units are standardized across all 30 covered European countries.
Example use cases
Solar farm site suitability screening
“I'm evaluating a potential solar installation near latitude 41.9, longitude 12.5 in Italy — can you tell me what direction the terrain faces there using a 250-metre buffer so I can assess sun exposure?”
Ski slope orientation assessment
“For the coordinate at latitude 47.3, longitude 11.1 in the Austrian Alps, what's the dominant slope aspect within 250 metres? I need to know if it's a north-facing run.”
Agricultural microclimate analysis
“Can you check the terrain aspect at latitude 51.5, longitude 0.1 in England using a 250-metre radius? I want to understand the hillside orientation for a crop suitability study.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-aspect-buffer-250mWhen to prefer
Choose this endpoint when you need terrain aspect (slope-facing direction) for a specific European point location and want a 250-metre neighbourhood analysis for a moderate spatial context — larger than a local 60m buffer but not as broad as a 1km+ area. Ideal for environmental siting, agriculture, renewable energy prospecting, or ecological assessments across Europe where slope orientation matters and standardized cross-country units are required.
Side effects
- Coordinate outside European coverage bounds (latitude 34–72.5°N, longitude -31.5–40.5°E) returns an error or no data
- Invalid or missing latitude/longitude fields return a validation error
- Flat terrain with no dominant gradient may return ambiguous or undefined aspect
- Payment failure (x402 protocol) prevents the call from completing
- Internal service error if the underlying DEM data has gaps at the queried location
