HALOWERK Nordic Land – Sweden Maximum Surface Slope
x402
HALOWERK Nordic Land – Sweden Maximum Surface Slope is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).
Returns the maximum adjacent-cell surface gradient (slope) for a given coordinate within Sweden's boundary, computed across an analysis grid.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Sweden; results outside it are rejected before payment.
Output
A numeric value representing the maximum adjacent-cell surface gradient (slope) computed across the analysis grid for the validated Swedish coordinate. Coordinates outside Sweden's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Construction site slope screening
“I'm evaluating a plot in Sweden at lat 63.82, lon 20.26 — can you tell me the maximum surface slope there so I can assess whether it's too steep for building?”
Agricultural suitability check
“I need to know the maximum terrain gradient at coordinates 57.70 latitude, 12.00 longitude in Sweden for a farmland suitability report — can you pull the slope data?”
Renewable energy site assessment
“We're scouting a wind turbine site near lat 65.58, lon 22.15 in Sweden — what's the maximum adjacent-cell surface slope there so we can flag any terrain stability concerns?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-max-slopeWhen to prefer
Choose this endpoint when you need maximum surface slope (steepest adjacent-cell gradient) specifically for a coordinate within Sweden, validated against the Natural Earth Sweden boundary. Prefer it over generic elevation APIs when you need pre-computed terrain gradient rather than raw elevation, and when Sweden-specific boundary validation and pay-per-call pricing ($0.003 USDC) are acceptable.
Side effects
- Coordinate outside Sweden's Natural Earth boundary — request rejected, no charge incurred
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing required latitude or longitude fields — schema validation error
- Payment failure via x402 protocol — request not processed
