x402
HALOWERK Southern Land – Greece Drainage Tendency is a paid API for AI agents from suedland.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 Greece, derived from terrain slope and ruggedness metrics.

How this service works
Relative runoff tendency derived from slope and ruggedness. The coordinate is validated against the Natural Earth boundary for Greece; results outside it are rejected before payment.
Output
A numeric score representing the relative runoff/drainage tendency at the queried coordinate, derived from slope steepness and terrain ruggedness. Coordinates outside the validated Natural Earth boundary for Greece are rejected before any charge is applied.
Example use cases
Agricultural land drainage assessment
“I'm evaluating a farm plot near Larissa, Greece at latitude 39.638 and longitude 22.418 — can you tell me the drainage tendency score so I know how susceptible the land is to surface runoff?”
Construction site suitability check
“We're planning a building project at 38.246 latitude, 21.735 longitude in Greece — what's the relative runoff tendency there based on terrain slope and ruggedness?”
Flood risk pre-screening for Greek property
“Before buying land in Crete at coordinates 35.338 N, 25.134 E, can you check the drainage tendency to see if the terrain is likely to channel heavy runoff across the site?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/gr-drainage-tendencyWhen to prefer
Use this endpoint when you need a terrain-derived drainage or runoff tendency index specifically for a location in Greece and want automatic boundary validation before payment. Prefer it over generic elevation APIs when the downstream use case requires hydrological context (runoff risk, land drainage suitability) rather than raw elevation data.
Side effects
- Coordinate outside Greece boundary — request rejected before payment, returns validation error
- Latitude or longitude out of allowed range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Invalid or missing coordinate fields — returns 400-level error
- Service unavailable or timeout — returns 5xx error
