x402
HALOWERK Europe Land – Aspect 1000m 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 dominant surface aspect (circular direction of steepest downhill gradient, clockwise from north) averaged over a 1,000-metre circular neighbourhood around a given European coordinate.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The service evaluates a circular 1,000 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
A standardized scalar value representing the dominant circular direction (in degrees, clockwise from north, 0–360) of the surface gradient within a 1,000-metre circular neighbourhood around the supplied coordinate, consistent across all 30 covered European countries.
Example use cases
Solar panel site suitability in Italy
“I'm evaluating a plot at latitude 43.7, longitude 11.2 in Tuscany — can you tell me which direction the hillside faces across a 1km radius? I need to know if it gets enough south-facing exposure for solar panels.”
Ski run orientation assessment
“For a proposed ski run near latitude 46.5, longitude 8.0 in the Swiss Alps, what is the dominant slope aspect over the surrounding 1,000 metres? I want to know if it's north-facing enough to hold snow.”
Wildfire risk modelling input
“As part of a wildfire risk model for a site at latitude 37.9, longitude -5.1 in southern Spain, I need the dominant terrain aspect within a 1km buffer around that point — can you get that for me?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-aspect-buffer-1000mWhen to prefer
Use this endpoint when you need a broader, landscape-scale terrain orientation (1km neighbourhood) rather than a local point estimate, which smooths out micro-topographic noise. Prefer over the 60m buffer variant when the use case involves regional planning, hydrology, solar exposure modelling, or wildfire risk where local terrain fluctuations should be averaged out. Coverage is standardised across 30 European countries, making it ideal for cross-border analysis.
Side effects
- Coordinates outside the European coverage bounding box (lat 34–72.5, lon -31.5–40.5) return an error or empty result
- Invalid or missing latitude/longitude values cause a validation error
- Flat terrain with no dominant gradient may return a noisy or undefined aspect value
- Payment failure (insufficient USDC) prevents the response from being returned under x402 protocol
