x402
HALOWERK Eastern Land – Romania Maximum Slope (ro-max-slope) is a paid API for AI agents from ostland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the maximum adjacent-cell surface gradient (steepest slope) across an analysis grid cell for a given WGS84 coordinate within Romania.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Romania; results outside it are rejected before payment.
Output
A numeric value representing the maximum adjacent-cell surface gradient (steepest slope angle or ratio) computed across the analysis grid at the requested Romanian coordinate. The coordinate is validated against the Natural Earth boundary for Romania before computation; requests outside Romania are rejected and return an error without incurring a charge.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a plot of land in Romania near coordinates 46.08 latitude and 23.57 longitude — can you get me the maximum slope gradient there so I know if it's too steep for machinery?”
Construction site terrain screening
“Before we proceed with a site survey, can you check the maximum slope gradient at latitude 44.43, longitude 26.10 in Romania to see if the terrain is too steep for a building project?”
Erosion risk pre-screening for a Romanian watershed
“Can you pull the maximum surface slope at latitude 47.15, longitude 27.58 in Romania? I want to assess the erosion risk based on how steep the steepest cell is.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/ro-max-slopeWhen to prefer
Choose this endpoint when you need the maximum (peak) slope gradient at a specific point in Romania, as opposed to the mean slope. It is particularly useful for worst-case terrain assessments such as erosion risk, machinery accessibility, or construction suitability screening. Prefer this over the mean slope endpoint when identifying the steepest micro-terrain feature within a grid cell matters. This is Romania-specific; use a different sibling endpoint for other European countries.
Side effects
- Coordinate outside Romania boundary: rejected before payment with a boundary validation error
- Coordinate outside the published European coverage range (lat 34–72.5, lon -31.5–40.5): validation error
- Missing or malformed latitude/longitude fields: schema validation error
- Payment failure via x402 protocol: request not processed
- Server-side terrain data unavailability: upstream data error
