x402
HALOWERK Europe Land – Local Relief Range (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 local relief range (max minus min surface elevation) within a 250-metre circular neighbourhood around a given European coordinate.

How this service works
Difference between maximum and minimum sampled surface elevation. 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 difference (in standardized units) between the maximum and minimum sampled surface elevation within a 250-metre circular buffer around the provided coordinate, covering any of 30 European countries.
Example use cases
Site suitability for solar farm
“I'm evaluating a potential solar farm site near latitude 41.3851, longitude 2.1734 in Spain — can you tell me the elevation range within 250 metres of that point so I can assess how flat the terrain is?”
Flood risk terrain assessment
“We're assessing flood risk for a property at latitude 51.5074, longitude -0.1278 in the UK — what's the local relief range within 250 metres to understand how much the land rises or drops nearby?”
Hiking trail difficulty estimation
“I want to know how rugged the terrain is around latitude 47.3769, longitude 8.5417 in Switzerland — can you get the elevation difference between the highest and lowest point within 250 metres of that location?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-local-relief-buffer-250mWhen to prefer
Choose this endpoint when you need a fast, point-specific measure of topographic roughness or local terrain variability at a single European location within a standardised 250-metre radius. It is ideal when you want a simple scalar relief index rather than a full elevation profile or DEM raster. Prefer it over larger-buffer variants when fine-grained local variation (sub-quarter-kilometre scale) is what matters for your use case.
Side effects
- Coordinate outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) returns an error
- Invalid or non-numeric latitude/longitude values cause a validation error
- Point falling in a data gap or coastal edge may return null or partial result
- Payment failure via x402 protocol results in 402 response and no data returned
