HALOWERK Eastern Land – Hungary Maximum Slope
x402
HALOWERK Eastern Land – Hungary Maximum Slope is a paid API for AI agents from ostland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the maximum adjacent-cell surface gradient (steepest slope) across the analysis grid for a given coordinate within Hungary.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Hungary; results outside it are rejected before payment.
Output
A numerical value representing the maximum adjacent-cell surface gradient (steepest slope angle or ratio) across the analysis grid centered on the provided coordinate. The coordinate is validated against Hungary's Natural Earth boundary; requests outside Hungary are rejected before any charge is applied.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a plot in Hungary for farming — can you get me the maximum slope gradient at latitude 46.9, longitude 18.4? I need to know how steep the terrain is before deciding if it's suitable.”
Construction site terrain risk screening
“We're looking at a potential construction site near coordinates 47.8 latitude, 20.5 longitude in Hungary — what's the maximum surface slope there so we can assess erosion and stability risk?”
Hiking trail difficulty mapping
“I'm planning a hiking route through Hungary and need to know the steepest terrain gradient near latitude 47.5, longitude 19.8 — can you pull the maximum slope for that spot?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hu-max-slopeWhen to prefer
Choose this endpoint when you need the maximum (steepest) slope value specifically for a location in Hungary and want coordinate boundary pre-validation before incurring any cost. Prefer this over generic elevation APIs when you need the maximum adjacent-cell gradient metric specifically, and over regional European terrain APIs when you need Hungary-specific validation guarantees.
Side effects
- Coordinate outside Hungary boundary: rejected before payment with a boundary validation error
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation error
- Missing required latitude or longitude parameter: request rejected with a validation error
- Network or service timeout: no result returned, no charge
