x402
HALOWERK Baltic Land – Drainage Tendency (Germany) is a paid API for AI agents from baltikum.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 Germany, 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 Germany; results outside it are rejected before payment.
Output
A numeric relative runoff/drainage tendency value derived from the terrain slope and surface ruggedness at the queried coordinate. Higher values indicate greater tendency for surface runoff; the result is only returned for coordinates validated to fall within Germany's boundary.
Example use cases
Construction site drainage assessment
“We're evaluating a plot at latitude 51.34, longitude 12.38 in Germany for a warehouse build — can you check the drainage tendency there to see if we'd have surface runoff issues?”
Agricultural field water management
“I'm managing farmland near 48.75°N, 11.42°E in Bavaria — what's the relative runoff tendency for that site so I know how to plan irrigation and drainage?”
Flood risk pre-screening for insurance
“Can you pull the drainage tendency score for coordinates 53.55°N, 10.00°E in Hamburg to help us pre-screen flood runoff risk for an insurance underwriting model?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/de-drainage-tendencyWhen to prefer
Choose this endpoint when you need a lightweight, cost-efficient terrain-derived drainage tendency score specifically for locations within Germany, without requiring full hydrological modelling. It is ideal for pre-screening sites for surface runoff risk, enriching geospatial datasets, or supporting land-use and construction decisions. Prefer it over general GIS APIs when you want a pre-computed slope-and-ruggedness-based index rather than raw elevation data.
Side effects
- Coordinate outside Germany's Natural Earth boundary — request rejected before payment is processed
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — schema validation failure
- Payment failure via x402 protocol — no result returned
