x402
HALOWERK Nordic Land – Solar Orientation Index (Iceland) 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 derived from aspect and slope for a given coordinate in Iceland, validated against the Natural Earth Iceland boundary.

How this service works
South-facing slope orientation index derived from aspect and slope. The coordinate is validated against the Natural Earth boundary for Iceland; results outside it are rejected before payment.
Output
A numeric south-facing slope orientation index derived from terrain aspect and slope angle for the queried Icelandic coordinate. Returns a computed score indicating how favorably oriented the surface is toward the south for solar exposure. Coordinates outside the Natural Earth boundary for Iceland are rejected before any payment is processed.
Example use cases
Solar farm site selection in Iceland
“I'm evaluating a plot near Reykjavik at 64.1°N, 22.0°W for a solar installation — can you get me the south-facing slope orientation index for that coordinate?”
Agricultural solar exposure assessment
“We're considering farming land in Iceland at latitude 65.3 and longitude -18.1 — can you check the solar orientation index to see how much southward sun exposure the slope gets?”
Geothermal tourism lodge siting
“I need to assess a hillside site in Iceland at 63.9°N, 20.5°W to understand how south-facing the terrain is before we choose it for a passive-solar lodge design.”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/is-solar-orientationWhen to prefer
Choose this endpoint when you need a terrain-derived solar orientation score specifically for locations within Iceland. It is ideal for solar site assessment, land-use planning, agricultural suitability analysis, or passive solar building siting in Iceland. Unlike generic elevation or aspect APIs, it combines aspect and slope into a single south-facing orientation index and enforces Iceland-boundary validation, making it reliable and cost-efficient for Iceland-scoped workflows.
Side effects
- Coordinate outside Iceland boundary — request rejected before payment with a boundary validation error
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed or missing coordinate parameters — input validation error
- Network or service timeout — retry recommended
- Payment failure via x402 protocol — transaction not completed, result not returned
