HALOWERK Nordic Land – Finland Drainage Tendency
x402
HALOWERK Nordic Land – Finland 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 tendency score for a WGS84 coordinate in Finland, derived from terrain slope and surface ruggedness, with boundary validation against Finland's Natural Earth polygon.

How this service works
Relative runoff tendency derived from slope and ruggedness. The coordinate is validated against the Natural Earth boundary for Finland; results outside it are rejected before payment.
Output
A numerical relative runoff tendency value for the queried Finnish coordinate, computed from local terrain slope and surface ruggedness. Coordinates outside Finland's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Site suitability for agricultural drainage
“I'm evaluating farmland near Tampere, Finland — can you check the relative runoff tendency at latitude 61.52, longitude 23.61 to understand how well the terrain drains?”
Pre-construction hydrological assessment
“We're planning a building project at 65.01°N, 25.47°E in Finland and need the drainage tendency score based on local slope and ruggedness before we proceed.”
Wetland restoration candidate screening
“For a wetland restoration study, can you pull the relative drainage tendency for the Finnish site at latitude 68.9, longitude 27.1 — low drainage tendency spots are what we're targeting.”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/fi-drainage-tendencyWhen to prefer
Choose this endpoint when you need a terrain-based hydrological drainage tendency specifically for a point location in Finland, particularly when you want a fast, per-coordinate score derived from slope and ruggedness rather than soil texture or land cover. It is preferable over generic DEM tools when you need boundary-validated, pay-per-call granularity and when Finland is your region of interest. For soil texture, pH, or organic carbon data, use the sibling SoilGrids endpoints on the same provider.
Side effects
- Coordinate outside Finland's Natural Earth boundary — request rejected with a boundary validation error, no charge applied
- Latitude or longitude outside the declared European coverage bounds (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Missing latitude or longitude parameter — request rejected with a missing-field error
- Payment failure (x402) — request not processed
- Internal computation error if elevation data is unavailable for the queried tile
