HALOWERK Southern Land – Spain Surface Aspect
x402
HALOWERK Southern Land – Spain Surface Aspect is a paid API for AI agents from suedland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the circular direction (0–360°, clockwise from north) of the dominant surface gradient for a given coordinate within Spain.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Spain; results outside it are rejected before payment.
Output
A numeric value representing the dominant surface aspect angle in degrees (0–360°, clockwise from north) for the queried coordinate within Spain. Coordinates outside the Spain boundary are rejected before any charge is applied.
Example use cases
Solar farm site suitability check
“I'm evaluating a plot near Seville at latitude 37.35, longitude -5.98 — can you tell me the aspect angle of the terrain there so I can assess whether it gets good southward sun exposure?”
Vineyard slope orientation assessment
“I need to know which direction the hillside faces at my vineyard site in La Rioja, coordinates latitude 42.46, longitude -2.51 — give me the dominant surface gradient direction in degrees.”
Erosion risk mapping for farmland
“For the agricultural parcel at latitude 41.1, longitude -0.9 in Aragon, what is the surface aspect angle? I need it to model which way water runoff flows across the slope.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/es-aspectWhen to prefer
Choose this endpoint when you need terrain aspect (slope direction) data specifically for coordinates within Spain, and require pre-query geographic validation to avoid wasted calls. Ideal for land suitability analysis, solar orientation assessments, agricultural planning, hydrological modelling, or any use case where knowing which compass direction a slope faces is critical.
Side effects
- Coordinate outside Spain boundary: request rejected before payment, error response indicating out-of-coverage area
- Latitude or longitude outside the accepted WGS84 range for European coverage: validation error
- Malformed input (missing or non-numeric lat/lon): schema validation error
- Network or service timeout: no result returned, retry recommended
- Edge case flat terrain with no dominant gradient: may return null or undefined aspect
