HALOWERK Central Land – CZ Drainage Tendency
x402
HALOWERK Central Land – CZ Drainage Tendency is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the relative runoff tendency for a geographic coordinate in Czechia, derived from terrain slope and surface ruggedness using Copernicus DEM data.

How this service works
Relative runoff tendency derived from slope and ruggedness. The coordinate is validated against the Natural Earth boundary for Czechia; results outside it are rejected before payment.
Output
A numeric value representing the relative runoff tendency at the queried coordinate, derived from terrain slope and surface ruggedness within the local analysis grid. Coordinates outside the Czechia Natural Earth boundary are rejected before any charge is applied.
Example use cases
Flood risk screening for a site
“I'm evaluating a potential construction site near Brno at lat 49.19, lon 16.61 — can you check its drainage tendency score based on slope and ruggedness so I know how prone it is to surface runoff?”
Agricultural drainage planning
“For a farm parcel in southern Bohemia at coordinates 49.05 latitude, 14.47 longitude, what's the relative runoff tendency? I need to decide whether to invest in drainage infrastructure.”
Environmental impact assessment
“We're doing an environmental review for a road project at lat 50.76, lon 15.05 in the Czech Republic — pull the drainage tendency from slope and terrain ruggedness for that spot.”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/cz-drainage-tendencyWhen to prefer
Choose this endpoint when you need terrain-derived hydrological runoff tendency specifically for points within Czechia, based on Copernicus DEM slope and ruggedness data. It is ideal for site assessments, environmental modeling, agricultural planning, or infrastructure risk screening within Czech territory. The coordinate boundary validation ensures charges only occur for valid in-scope locations.
Side effects
- Coordinate outside Czechia boundary → rejected with validation error before payment
- Latitude or longitude outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) → schema validation failure
- Missing latitude or longitude in request body → 400 Bad Request
- Payment not provided or insufficient → 402 Payment Required
- Server-side DEM data unavailability → 500 or service error
