x402
HALOWERK Nordic Land – SE 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 derived from aspect and slope data for a given coordinate within Sweden.

How this service works
South-facing slope orientation index derived from aspect and slope. The coordinate is validated against the Natural Earth boundary for Sweden; results outside it are rejected before payment.
Output
A numeric south-facing slope orientation index derived from terrain aspect and slope at the queried coordinate. Coordinates outside Sweden's Natural Earth boundary are rejected before any charge is applied. The index indicates how optimally the slope faces south, useful for solar energy, agriculture, and land use planning.
Example use cases
Solar farm site pre-screening in Sweden
“I'm evaluating a site near Falun at 60.61 north, 15.63 east for a solar farm — can you give me the south-facing slope orientation index so I know whether it's worth pursuing?”
Agricultural solar suitability check
“We're advising a Swedish farmer at latitude 55.92, longitude 13.50 on whether their sloping fields are well-oriented for agrivoltaic panels — can you pull the solar orientation index for that spot?”
Forestry land reuse assessment
“We're looking at repurposing a cleared forest plot at 63.18 north, 14.72 east in Sweden for renewable energy — what's the solar slope orientation score for that location?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-solar-orientationWhen to prefer
Choose this endpoint when you need a quantitative solar orientation metric specifically for coordinates within Sweden, derived from aspect and slope. It is ideal for site-selection workflows, solar energy feasibility assessments, and land-use planning within the Nordic region. The built-in Sweden boundary validation ensures charges are only incurred for valid queries. Prefer this over generic elevation or aspect APIs when a single aggregated south-facing orientation index is needed for Swedish terrain.
Side effects
- Coordinate outside Sweden's Natural Earth boundary — request rejected with boundary validation error, no charge applied
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Missing required latitude or longitude fields — request rejected with input validation error
- Coordinate in a data-sparse terrain area — may return null or low-confidence index
- Network timeout or service unavailability — HTTP 5xx error
