HALOWERK Southern Land – Portugal Drainage Tendency
x402
HALOWERK Southern Land – Portugal 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 tendency for a geographic point in Portugal, derived from terrain slope and surface ruggedness using DEM analysis.

How this service works
Relative runoff tendency derived from slope and ruggedness. The coordinate is validated against the Natural Earth boundary for Portugal; results outside it are rejected before payment.
Output
A numeric index representing the relative runoff tendency at the queried location, derived from terrain slope and surface ruggedness. Coordinates outside the Natural Earth boundary for Portugal are rejected before any payment is processed.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a plot near Évora at 38.57°N, 7.91°W — can you check the drainage tendency there so I know if the terrain is likely to channel runoff away or pool water on the surface?”
Site risk screening for construction
“We're planning a small development at 41.15°N latitude, -8.60°W longitude in Portugal. Can you pull the drainage tendency for that coordinate so we can flag any high-runoff risk in our site report?”
Reforestation terrain prioritization
“I need to prioritize reforestation areas in Portugal — can you get the runoff tendency for the coordinate at 39.4°N, -8.2°W to see if the slope and ruggedness would cause erosion problems?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-drainage-tendencyWhen to prefer
Use this endpoint when you need a quick, point-based runoff tendency estimate for a location in Portugal and terrain slope plus ruggedness are the relevant factors. Prefer it over general GIS tools when you need a pay-per-call, API-accessible scalar metric without managing raster datasets. Particularly useful in land assessment workflows combining multiple HALOWERK Southern Land signals (e.g. soil texture, elevation SD, crop cover) for the same Portuguese coordinate.
Side effects
- Coordinate outside Portugal boundary — rejected with a validation error before payment is charged
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Non-numeric or malformed coordinate values — input validation failure
- Service unavailable or upstream DEM data error — 5xx response
