x402
HALOWERK Nordic Land – Iceland 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 the relative runoff/drainage tendency for a coordinate in Iceland, 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 Iceland; results outside it are rejected before payment.
Output
A numeric or categorical drainage tendency value derived from slope and surface ruggedness for the queried coordinate. Coordinates outside Iceland's Natural Earth boundary are rejected before any charge is applied. The response reflects relative runoff likelihood, where higher values indicate steeper or more rugged terrain that drains water more rapidly.
Example use cases
Construction site drainage assessment
“I'm planning a building project near Reykjavik at latitude 64.10, longitude -21.90 — can you check the drainage tendency there to see if runoff from the terrain could be a problem?”
Agricultural land suitability screening
“I'm evaluating farmland in Iceland at lat 65.68, lon -18.10 — what's the relative drainage tendency based on slope and ruggedness so I know if the land retains water or drains well?”
Hiking trail safety evaluation
“We're scouting a hiking route in Iceland near lat 63.98, lon -19.55 — can you pull the drainage tendency score so we know whether the terrain channels runoff toward the trail?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/is-drainage-tendencyWhen to prefer
Use this endpoint when you need a terrain-derived hydrology signal (slope + ruggedness → runoff tendency) specifically for locations within Iceland. It is ideal for environmental assessment, land-use planning, agricultural screening, or construction risk analysis where drainage behaviour must be estimated without running a full hydrological model. Prefer this over raw elevation APIs when you need a pre-computed, actionable drainage index rather than raw DEM values.
Side effects
- Coordinate outside Iceland's Natural Earth boundary — request rejected with a boundary validation error and no charge
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed or missing coordinate fields — HTTP 400 bad request
- Service unavailability or timeout — HTTP 5xx error
