How this service works
Mean SoilGrids sand fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Bulgaria; results outside it are rejected before payment.
Output
A numeric mean sand fraction value (from SoilGrids) for the 0–5 cm topsoil layer at the queried coordinate. Coordinates outside Bulgaria are rejected before any charge is applied.
Example use cases
Agricultural soil texture assessment
“I'm evaluating farmland near Plovdiv — can you check the sand fraction in the top 5 cm of soil at latitude 42.15, longitude 24.75 in Bulgaria?”
Soil drainage suitability screening
“For a site at lat 43.08, lon 25.62 in Bulgaria, what is the topsoil sand content? I need to assess how well-draining the soil is.”
Environmental baseline data collection
“I'm building a land-use dataset for central Bulgaria — fetch the SoilGrids sand fraction for the 0–5 cm layer at coordinates 41.90 latitude, 23.55 longitude.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/bg-soil-sandWhen to prefer
Use this endpoint when you need a point-level SoilGrids sand fraction value specifically within Bulgaria. It is ideal for agricultural feasibility studies, soil texture classification, land suitability analysis, or environmental data enrichment where topsoil sand content at the 0–5 cm depth is required. Prefer this over generic soil APIs when you need cost-effective micropayment access ($0.004/call) with boundary validation guaranteeing the coordinate is within Bulgaria.
Side effects
- Coordinate falls outside Bulgaria's Natural Earth boundary — request rejected with no charge
- Latitude or longitude out of the European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — input schema error
- Payment failure via x402 protocol — transaction not processed
