x402
HALOWERK Nordic Land – SE 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 2026-09-15).
Returns a relative runoff/drainage tendency score for a coordinate in Sweden, 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 Sweden; results outside it are rejected before payment.
Output
A numeric relative drainage tendency value derived from terrain slope and ruggedness at the queried coordinate, reflecting the likelihood of surface water runoff at that location within Sweden. Coordinates outside the Sweden boundary are rejected before any charge is applied.
Example use cases
Site suitability for construction drainage
“I'm evaluating a plot near Gothenburg at 57.71° N, 11.97° E — can you get the drainage tendency score so I know how much surface runoff risk we're dealing with before we break ground?”
Agricultural field waterlogging risk
“For our farmland at 55.97° N, 14.12° E in southern Sweden, can you check the relative runoff tendency? We need to decide whether to add drainage channels this season.”
Ecological wetland corridor mapping
“We're mapping potential wetland corridors in central Sweden. Can you pull the drainage tendency for the point at 62.40° N, 16.50° E to see if the terrain naturally funnels water there?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-drainage-tendencyWhen to prefer
Choose this endpoint when you need a terrain-derived drainage or runoff tendency score specifically for a point within Sweden. It is purpose-built for Swedish geography with boundary validation before billing, making it cost-safe for coordinate checking. Prefer it over generic elevation or slope APIs when the specific output required is a runoff/drainage tendency index informed by both slope and ruggedness together.
Side effects
- Coordinate outside Sweden boundary — rejected before payment with a validation error
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Malformed or missing coordinate fields — HTTP 400 bad request
- Service unavailable or upstream terrain data error — HTTP 5xx
