x402
HALOWERK Southern Land Portugal Aspect is a paid API for AI agents from suedland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the dominant surface slope direction (aspect) in degrees clockwise from north for a given coordinate within Portugal.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Portugal; results outside it are rejected before payment.
Output
A numeric value representing the circular direction of the dominant surface gradient in degrees (0–360, clockwise from north), reflecting the primary facing direction of the terrain at the queried coordinate within Portugal. Coordinates outside the Portugal boundary are rejected before any charge is applied.
Example use cases
Vineyard site suitability assessment
“I'm evaluating a potential vineyard site in Portugal at latitude 41.15, longitude -7.85 — can you tell me which direction the slope faces there? South-facing slopes get the most sun and I want to check before we invest.”
Solar farm orientation planning
“We're planning a solar installation on land near latitude 37.95, longitude -8.20 in Portugal and need to know the dominant terrain aspect — which direction does the hillside face at that coordinate?”
Erosion risk mapping for agricultural land
“For our land parcel in Portugal at latitude 39.60, longitude -7.50, what is the aspect — the direction the surface slopes toward — so we can model rainfall runoff and erosion risk?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-aspectWhen to prefer
Use this endpoint when you need terrain aspect (slope-facing direction) specifically for coordinates within Portugal, especially as part of a broader land suitability, agricultural planning, or environmental analysis workflow. It is pre-validated against the Portugal boundary, ensuring you are not charged for out-of-bounds requests. Prefer it over generic DEM APIs when you need a cost-effective, pay-per-call micro-service for Portugal-specific terrain analysis.
Side effects
- Coordinate outside Portugal boundary — rejected with an error before payment is processed
- Latitude or longitude outside valid European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Invalid or missing coordinate fields — request rejected
- Network timeout or service unavailability
