x402
HALOWERK Nordic Land – Drainage Tendency is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns a relative runoff/drainage tendency index for a coordinate in Norway, derived from terrain slope and surface ruggedness.

How this service works
Relative runoff tendency derived from slope and ruggedness. The coordinate is validated against the Natural Earth boundary for Norway; results outside it are rejected before payment.
Output
A numeric drainage tendency index for the queried Norwegian coordinate, derived from local slope steepness and surface ruggedness, indicating the relative propensity for surface water runoff at that location. Coordinates outside Norway's Natural Earth boundary are rejected before any charge is incurred.
Example use cases
Agricultural waterlogging risk assessment
“I'm evaluating a farmland plot near Trondheim at lat 63.43, lon 10.39 — can you check the drainage tendency there so I know if the terrain is prone to waterlogging?”
Construction site drainage screening
“We're scoping a construction project in Norway at coordinates 60.2 latitude, 11.1 longitude — give me the runoff and drainage tendency score based on the local slope and ruggedness.”
Ecological habitat suitability mapping
“For a wetland habitat study at lat 68.4 and lon 17.8 in Norway, can you pull the terrain-derived drainage tendency so I can understand surface water retention likelihood?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/no-drainage-tendencyWhen to prefer
Choose this endpoint when you need a terrain-derived, slope-and-ruggedness-based drainage tendency score specifically for Norwegian coordinates. It is well-suited for hydrological screening, site assessments, or environmental analyses where a quick, per-point runoff tendency index is needed without running a full hydrological model. It complements sibling endpoints on the same platform (soil texture, organic carbon, land cover) for comprehensive land characterisation in Norway.
Side effects
- Coordinate outside Norway's Natural Earth boundary — rejected with an out-of-bounds error, no charge applied
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon −31.5–40.5) — schema validation error
- Missing latitude or longitude field — request rejected with a 422 or 400 error
- Service unavailable or upstream terrain data error — 5xx response
