HALOWERK Nordic Land – Finland Solar Orientation Index
x402
HALOWERK Nordic Land – Finland Solar Orientation Index is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns a south-facing slope orientation index for a given coordinate inside Finland, derived from terrain aspect and slope data.

How this service works
South-facing slope orientation index derived from aspect and slope. The coordinate is validated against the Natural Earth boundary for Finland; results outside it are rejected before payment.
Output
A numeric south-facing slope orientation index computed from terrain aspect and slope data for the queried Finnish coordinate. Coordinates outside the Finland boundary (validated against Natural Earth) are rejected before any charge is applied.
Example use cases
Solar farm site screening in Finland
“I'm evaluating a potential solar farm site near Oulu, Finland at latitude 65.01 and longitude 25.47 — can you tell me the south-facing slope orientation index so I know if the terrain aspect is favorable?”
Cabin lot solar suitability check
“We're buying a cabin plot in Finnish Lapland at coordinates 68.5 latitude and 27.3 longitude — what's the south-facing orientation score for the slope there? We want to know if rooftop solar would work well.”
Reforestation slope aspect assessment
“For our reforestation project in Finland at latitude 62.8, longitude 23.1, can you give me the south-facing slope orientation index? We need it to decide which tree species are best suited to the aspect and sun exposure.”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/fi-solar-orientationWhen to prefer
Choose this endpoint when you need a terrain-based solar orientation score specifically for a coordinate inside Finland, particularly for land assessment, solar energy planning, or ecological analysis. It is distinct from raw aspect or slope endpoints because it synthesises both into a single south-facing index, and it pre-validates against Finland's boundary so invalid coordinates are rejected before payment.
Side effects
- Coordinate outside Finland's Natural Earth boundary — request rejected with a geographic bounds error, no charge applied
- Latitude or longitude outside published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — input schema validation error
- Payment failure via x402 protocol — request not processed
