x402
HALOWERK Atlantic Land – France Maximum Slope (fr-max-slope) is a paid API for AI agents from atlantikland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the maximum adjacent-cell surface slope gradient across the analysis grid for a given coordinate within France, validated against the Natural Earth boundary.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for France; results outside it are rejected before payment.
Output
A numeric value representing the maximum adjacent-cell surface slope gradient across the analysis grid at the specified coordinate. Results are only returned for valid coordinates within the Natural Earth boundary of France; coordinates outside this boundary are rejected.
Example use cases
Construction site terrain suitability check
“I'm evaluating a site near Grenoble at latitude 45.18, longitude 5.72 — can you tell me the maximum slope gradient there so I can assess whether it's too steep to build on?”
Erosion risk assessment for agricultural land
“I need the maximum adjacent-cell slope for a field at latitude 43.60, longitude 3.88 in southern France to estimate erosion risk for our soil conservation report.”
Hiking trail gradient analysis
“Can you get the steepest slope value at latitude 42.80, longitude 0.15 in the French Pyrenees? I want to know the maximum gradient across the grid for that area to plan trail difficulty ratings.”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/fr-max-slopeWhen to prefer
Use this endpoint when you need the maximum (peak) slope gradient at a point in France, as opposed to the mean slope (which is a sibling endpoint). Prefer this when assessing worst-case terrain steepness, erosion susceptibility, or maximum incline for engineering and environmental analysis. It is specifically scoped to France and will reject coordinates outside the boundary, so it is appropriate when working exclusively within French territory.
Side effects
- Coordinate outside France's Natural Earth boundary — request rejected before payment
- Latitude or longitude out of allowed range (lat: 34–72.5, lon: -31.5–40.5) — validation error
- Missing required latitude or longitude parameter — schema validation failure
- Network timeout or service unavailability
- Payment failure via x402 protocol — no result returned
