How this service works
Measures topsoil clay for exactly two European coordinates with one method and reports the signed difference and winner where meaningful.
Output
Returns the topsoil clay measurement for each of the two input coordinates, the signed numerical difference between them, and an indication of which location has the higher clay content where the difference is meaningful.
Example use cases
Farmland suitability comparison for clay-loving crops
“I'm deciding between two parcels for growing wheat — one near Toulouse at 43.6047°N, 1.4442°E and one near Lyon at 45.7640°N, 4.8357°E. Which one has higher topsoil clay and what's the difference?”
Real estate due diligence on soil composition
“Before buying land, compare the topsoil clay at these two sites: one at 51.5074°N, -0.1278°E labeled 'Kent plot' and one at 53.4808°N, -2.2426°E labeled 'Manchester plot'. Which has more clay?”
Environmental site assessment soil clay check
“Can you check topsoil clay levels at two coordinates for my environmental report — 47.3769°N, 8.5417°E named 'Zurich site' and 48.2082°N, 16.3738°E named 'Vienna site'? I need the signed difference and which site wins.”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/compare-two-soil-clayWhen to prefer
Use this endpoint when you need a focused, authoritative clay-content comparison between exactly two European land sites in a single call. It is more precise than general soil lookup tools because it is purpose-built for pairwise European topsoil clay comparison and directly returns the signed delta and winner, saving post-processing steps. Prefer it over multi-site ranking endpoints when you have exactly two locations and need a direct head-to-head clay result.
Side effects
- Coordinates outside the European coverage bounds (latitude 34–72.5°N, longitude -31.5–40.5°E) return a validation error
- Fewer or more than exactly two locations in the request body cause a schema validation failure
- Missing required latitude or longitude fields return a 400-level error
- Ambiguous or identical coordinates may yield a zero difference with no clear winner
