x402
HALOWERK Southern Land — Spain 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 the relative runoff/drainage tendency for a coordinate in Spain, 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 Spain; results outside it are rejected before payment.
Output
A numeric or categorical score representing the relative runoff/drainage tendency at the queried coordinate, derived from local slope steepness and terrain ruggedness. Points outside the Spain boundary are rejected before any charge is made.
Example use cases
Farmland drainage assessment in Spain
“I'm evaluating a plot near Zaragoza at latitude 41.65, longitude -0.88 — can you check its drainage tendency so I know if it's prone to waterlogging or runoff?”
Hydrological risk screening for construction
“We're planning a site near Seville at latitude 37.39, longitude -5.99 — what's the relative runoff tendency there based on slope and ruggedness?”
Ecological site characterization
“For a nature reserve study at latitude 42.10, longitude -2.45 in Spain, I need the terrain drainage tendency to understand surface water flow patterns.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/es-drainage-tendencyWhen to prefer
Choose this endpoint when you need a fast, low-cost per-point drainage or runoff tendency metric for locations within Spain, derived from terrain morphology (slope + ruggedness). It is ideal for land suitability screening, agricultural planning, environmental studies, or construction risk assessment where hydrological terrain characteristics matter. Prefer it over full hydrological modeling services when a relative index is sufficient and cost per query needs to be minimal.
Side effects
- Coordinate outside Spain boundary (Natural Earth polygon) — request rejected with an error before payment
- Latitude or longitude out of the accepted European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — input schema validation error
- Network or server timeout — retry recommended
