How this service works
Mean SoilGrids clay fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Croatia; results outside it are rejected before payment.
Output
A numeric value representing the mean clay fraction (typically expressed as g/kg or percentage) for the 0–5 cm topsoil layer at the queried coordinate, sourced from SoilGrids. Coordinates outside Croatia's boundary are rejected before the response is returned.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a farm plot near Osijek, Croatia — can you check the clay fraction in the top 5 cm of soil at latitude 45.55, longitude 18.69? I need to know if the soil is heavy clay before we plan the drainage.”
Environmental site characterization
“We're doing a site survey near Split, Croatia at coordinates 43.51 latitude, 16.44 longitude. Can you pull the SoilGrids mean clay content for the 0–5 cm layer at that point?”
Precision viticulture soil profiling
“I'm planning a vineyard in the Croatian hinterland around 45.2 latitude, 16.0 longitude — what's the clay fraction in the topsoil there according to SoilGrids?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hr-soil-clayWhen to prefer
Choose this endpoint when you need SoilGrids clay fraction data specifically for a point within Croatia and want geographic boundary validation enforced server-side. It is ideal for Croatian agricultural, environmental, or land-use applications where only Croatia-scoped data is relevant. If you need clay data for other European countries, look for sibling endpoints covering those boundaries.
Side effects
- Coordinate outside Croatia's Natural Earth boundary — request rejected with a geographic validation error before any charge is incurred
- Latitude or longitude outside the European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Missing latitude or longitude in request body — validation error
- Network or upstream SoilGrids data unavailability — service error response
- Malformed JSON payload — parse error
