x402
HALOWERK Europe Land – Solar Orientation Index (Polygon) is a paid API for AI agents from euroland.halowerk.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-15).
Returns a south-facing slope orientation index derived from aspect and slope for a user-supplied WGS84 polygon within Europe.

How this service works
South-facing slope orientation index derived from aspect and slope. The service evaluates the bounded polygon supplied by the caller and returns standardized units across all 30 covered countries.
Output
A standardized south-facing slope orientation index value for the submitted polygon, derived from aspect and slope data, consistent across all 30 covered European countries.
Example use cases
Vineyard site solar suitability assessment
“I'm evaluating a potential vineyard plot in Burgundy — can you compute the south-facing slope orientation index for this polygon? Vertices: [4.83,47.05], [4.84,47.05], [4.84,47.06], [4.83,47.06].”
Solar farm pre-screening in Germany
“We're pre-screening land parcels in Bavaria for a solar farm project. Can you get the solar orientation index for this polygon: [11.12,48.22], [11.13,48.22], [11.13,48.23], [11.12,48.23]?”
Agricultural land valuation in Spain
“I need the south-facing slope orientation score for this Spanish agricultural parcel to include in a land valuation report — polygon coordinates: [-3.70,40.41], [-3.69,40.41], [-3.69,40.42], [-3.70,40.42].”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-solar-orientation-parcelWhen to prefer
Use this endpoint when you need a standardized solar orientation metric for an arbitrary polygon parcel boundary rather than a fixed circular buffer. It is ideal for actual land parcel shapes (cadastral boundaries, field outlines) and when precise polygon geometry matters for solar suitability analysis across any of 30 European countries.
Side effects
- Polygon has fewer than 3 coordinate pairs — returns validation error
- Coordinates fall outside the European coverage area (longitude outside -31.5–40.5 or latitude outside 34–72.5) — returns out-of-bounds error
- Polygon span exceeds 0.25 degrees — returns size limit error
- Polygon has more than 100 vertices — returns validation error
- Malformed coordinate arrays — returns schema validation error
