How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Spain; results outside it are rejected before payment.
Output
A numerical value representing the maximum adjacent-cell surface slope gradient across the analysis grid at the specified coordinate in Spain. Coordinates outside the validated Natural Earth boundary for Spain are rejected before any charge is applied.
Example use cases
Site suitability check for solar farm
“I'm evaluating a potential solar farm site near latitude 38.5, longitude -5.2 in Spain — what's the maximum terrain slope there so I can assess whether it's too steep for panel installation?”
Flood risk terrain assessment
“Can you get the maximum surface slope gradient at coordinates 41.65 latitude, -0.88 longitude in Spain? I need to understand how steep the terrain is for a flood runoff risk analysis.”
Agricultural land grading evaluation
“I'm looking at farmland near latitude 37.3, longitude -5.9 in Spain and need to know the steepest slope gradient in the area — can you pull the max adjacent-cell surface slope for that coordinate?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/es-max-slopeWhen to prefer
Use this endpoint when you specifically need the maximum adjacent-cell surface gradient (peak steepness) for a coordinate in Spain, as opposed to mean elevation, elevation standard deviation, or slope direction. It is ideal for terrain suitability analysis, slope risk assessment, and land use planning where the worst-case steepness is the key metric.
Side effects
- Coordinate outside Spain's Natural Earth boundary — request rejected before payment
- Latitude or longitude out of published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — input schema validation error
- Payment failure via x402 protocol — request not processed
