HALOWERK Nordic Land – Local Relief (Sweden)
x402
HALOWERK Nordic Land – Local Relief (Sweden) is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the difference between maximum and minimum surface elevation (local relief) for a given WGS84 coordinate within Sweden.

How this service works
Difference between maximum and minimum sampled surface elevation. The coordinate is validated against the Natural Earth boundary for Sweden; 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 grid centered on the provided coordinate. Coordinates outside the Natural Earth boundary for Sweden are rejected before payment is processed.
Example use cases
Terrain suitability for construction site
“I'm evaluating a potential construction site in Sweden at latitude 57.7, longitude 11.9 — can you tell me the local relief there so I know how flat or rugged the ground is?”
Hiking trail difficulty assessment
“We're planning a hiking route near latitude 68.3, longitude 18.5 in northern Sweden. What's the local relief at that point so we can gauge how challenging the terrain will be?”
Agricultural land flatness check
“I need to assess whether the land at latitude 55.6, longitude 13.0 in Sweden is suitable for large-scale farming — can you look up the local relief to see how much elevation variation there is?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-local-reliefWhen to prefer
Choose this endpoint when you need a fast, paid, per-point local relief value specifically for coordinates within Sweden. It is ideal when you need topographic roughness/amplitude as a scalar metric for site assessment, land classification, or environmental modeling. Prefer it over general elevation APIs when you specifically need the max-minus-min relief metric (not just elevation), and when your workflow requires Sweden-specific boundary validation before billing.
Side effects
- Coordinate outside Sweden's Natural Earth boundary — request rejected before charge, returns a validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Malformed or missing coordinate fields — returns a 400-level error
- Network timeout or service unavailability — returns a 5xx error
