x402
HALOWERK Europe Land – Local Relief Range (1,000 m 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 difference between maximum and minimum surface elevation (local relief range) within a 1,000-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 1,000 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
A single numeric value representing the difference (in standardised elevation units, typically metres) between the maximum and minimum sampled surface elevation within a 1,000-metre circular buffer around the supplied WGS84 coordinate, covering up to 30 European countries.
Example use cases
Site suitability for construction project
“We're evaluating a site in the Alps near latitude 47.3769, longitude 8.5417 — can you tell me how much elevation variation there is within 1 km so we can assess how flat or hilly the terrain is?”
Agricultural land flatness assessment
“I need to know how rugged the terrain is within 1 kilometre of our farm in Spain at latitude 40.4168, longitude -3.7038 — specifically the difference between the highest and lowest elevation in that area.”
Renewable energy wind farm terrain screening
“We're screening a potential wind farm location in Denmark at latitude 56.2639, longitude 9.5018 — can you compute the local relief range within a 1,000-metre buffer to check for significant terrain obstacles?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-local-relief-buffer-1000mWhen to prefer
Choose this endpoint when you need a quick, standardised measure of terrain roughness or topographic variability at a single point in Europe using a 1,000-metre analysis radius. It is ideal for site assessment, land suitability screening, or environmental modelling workflows where a circular neighbourhood analysis is appropriate. Use the 60-metre buffer sibling endpoint instead when fine-grained, highly localised relief is required.
Side effects
- Coordinate outside European coverage bounds (latitude 34–72.5, longitude −31.5–40.5) returns an error or null result
- Missing latitude or longitude parameter causes a validation error
- Coastal or border coordinates may fall partially outside covered land area, potentially reducing sample quality
- Payment failure (x402 protocol) blocks the request before computation
