HALOWERK Baltic Land – Poland Max Surface Slope
x402
HALOWERK Baltic Land – Poland Max Surface Slope is a paid API for AI agents from baltikum.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the maximum adjacent-cell surface gradient (steepest slope) across the analysis grid for a given coordinate within Poland.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Poland; results outside it are rejected before payment.
Output
A scalar value representing the maximum adjacent-cell surface gradient (steepest slope) across the analysis grid centered on the requested coordinate within Poland. Coordinates outside Poland's Natural Earth boundary are rejected before any charge is made.
Example use cases
Construction site terrain assessment
“Can you check the maximum surface slope at latitude 50.06, longitude 19.94 in Poland? I need to know how steep the steepest terrain gradient is before we evaluate this site for construction.”
Agricultural land suitability screening
“I'm looking at a plot in Poland at 51.75 latitude, 19.45 longitude — can you pull the maximum slope gradient so I can assess whether it's too steep for crop farming?”
Flood risk and runoff routing analysis
“What's the steepest surface gradient at coordinates 54.35, 18.65 in Poland? I'm modeling water runoff paths and need the max adjacent-cell slope for that area.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-max-slopeWhen to prefer
Use this endpoint when you specifically need the steepest slope metric (maximum adjacent-cell surface gradient) for a point in Poland. Prefer it over general elevation APIs when slope extremity — not mean elevation or average ruggedness — is the required output. It is well-suited for construction suitability, erosion risk, drainage routing, or agricultural land screening workflows focused on Polish territory.
Side effects
- Coordinate outside Poland boundary: request rejected before payment, returns validation error
- Latitude or longitude outside published European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation failure
- Malformed or missing coordinate fields: 400-level error
- Temporary upstream terrain data unavailability: 5xx error
