HALOWERK Land Compare – Two-Point Aspect Comparison
x402
HALOWERK Land Compare – Two-Point Aspect Comparison is a paid API for AI agents from landvergleich.halowerk.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-14).
Measures the dominant terrain aspect (compass-facing direction) at exactly two European coordinates and returns the signed difference plus which location wins.

How this service works
Measures dominant aspect for exactly two European coordinates with one method and reports the signed difference and winner where meaningful.
Output
Returns the dominant terrain aspect value (compass direction) for each of the two input coordinates, the signed numeric difference between them, and an indication of which location wins in terms of aspect orientation — useful for comparing sun-facing terrain characteristics across two European sites.
Example use cases
Solar farm site shortlisting
“I'm evaluating two plots for a solar installation — one near Lyon at 45.75°N, 4.85°E and another near Munich at 48.14°N, 11.58°E. Which site has the more south-facing aspect, and what's the difference?”
Agricultural parcel sun exposure check
“We're choosing between two vineyard parcels in Europe: site Alpha at latitude 41.9, longitude 12.5 and site Beta at latitude 43.3, longitude 5.4. Can you compare their dominant aspect and tell me which one has the better sun-facing slope for viticulture?”
Hiking trail comparison for sun exposure
“I'm planning two hiking routes — one starting near Innsbruck at 47.27°N, 11.39°E and another near Granada at 37.18°N, -3.60°W. Which trailhead faces more toward the sun based on terrain aspect, and by how much?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/compare-two-aspectWhen to prefer
Choose this endpoint when you need a precise, point-in-time comparison of terrain aspect (compass-facing direction) between exactly two European locations. It is ideal for site-selection tasks — solar farm placement, vineyard selection, building orientation — where knowing which of two specific coordinates has a more favorable aspect is the core question. Prefer this over the ranking endpoint (which handles 2–10 sites) when you have exactly two candidates and want a clean binary comparison with a signed difference.
Side effects
- Coordinates outside European coverage bounds (latitude 34–72.5°N, longitude −31.5–40.5°E) return a validation error
- Fewer or more than exactly 2 locations in the array returns a schema validation error
- Malformed or missing latitude/longitude fields cause a 400-level error
- Flat terrain with no meaningful aspect difference may return a null or tied winner
- Network timeouts possible for slow elevation data retrieval
