HALOWERK Central Land – CZ Mean Slope
x402
HALOWERK Central Land – CZ Mean Slope is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the mean first-order surface gradient (slope) at a given WGS84 coordinate within Czechia, derived from grid analysis.

How this service works
Mean first-order surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Czechia; results outside it are rejected before payment.
Output
A numeric value representing the mean first-order surface gradient (slope) across the analysis grid centered on the provided coordinate, expressed as a rate of elevation change. Coordinates outside the Czech Republic boundary are rejected before processing.
Example use cases
Construction site suitability check
“I'm evaluating a potential construction site near Prague at lat 50.05, lon 14.45 — can you get me the mean surface slope there so I know how steep the terrain is?”
Agricultural land gradient assessment
“We're assessing farmland suitability in the Czech Republic around lat 49.19, lon 16.61 — what's the average slope of the terrain at those coordinates?”
Hiking trail steepness lookup
“I'm planning a hiking route and want to know how steep the terrain is at lat 50.74, lon 15.74 in northern Czechia — give me the mean surface gradient for that point.”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/cz-mean-slopeWhen to prefer
Use this endpoint when you need a mean slope/gradient value for a specific point within Czechia and want a pay-per-call micro-payment model. Prefer this over general-purpose GIS tools when you only need slope for Czech coordinates and want low-latency, per-coordinate pricing. It is part of a suite of terrain and land-surface metrics for Central Europe, so it is well-suited for pipelines that also query elevation, aspect, or soil data for the same region.
Side effects
- Coordinate outside Czechia boundary — rejected with validation error before payment
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Missing required latitude or longitude parameter — request rejected
- Network timeout or upstream DEM data unavailability — service error response
- Payment not completed via x402 protocol — request not processed
