HALOWERK Southern Land – Local Relief (Spain)
x402
HALOWERK Southern Land – Local Relief (Spain) is a paid API for AI agents from suedland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the local relief (max minus min sampled surface elevation) for a given WGS84 coordinate within Spain.

How this service works
Difference between maximum and minimum sampled surface elevation. The coordinate is validated against the Natural Earth boundary for Spain; results outside it are rejected before payment.
Output
A numeric value representing the local relief in meters — the difference between the maximum and minimum sampled surface elevations within the analysis area centered on the given coordinate. Coordinates outside Spain's Natural Earth boundary are rejected before any charge is made.
Example use cases
Terrain suitability for solar farm
“We're evaluating a site for a solar farm near latitude 38.5, longitude -6.3 in Spain — can you get the local relief there so we know how flat or rugged the ground is?”
Hiking trail difficulty assessment
“I'm planning a hiking route near latitude 42.1, longitude -1.9 in Spain. What's the local elevation relief at that coordinate to help me judge how challenging the terrain will be?”
Agricultural land flatness check
“We're looking at farmland around latitude 39.2, longitude -0.8 in Spain — can you pull the local relief value to see how much elevation variation we're dealing with across the plot?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/es-local-reliefWhen to prefer
Choose this endpoint when you need terrain roughness or topographic variability at a specific point within Spain and want a simple scalar relief metric (max minus min elevation). It is purpose-built and validated for Spanish coordinates, making it more reliable than a generic elevation API that might not enforce geographic boundaries or sample consistently.
Side effects
- Coordinate outside Spain's Natural Earth boundary — request rejected with validation error before payment
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Elevation data unavailable for remote or water-covered coordinates
- Network timeout or service unavailability returning 5xx error
