How this service works
Mean SoilGrids coarse-fragment volume 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 value representing the mean volumetric coarse-fragment content (% vol) of the 0–5 cm soil layer at the requested coordinate, derived from SoilGrids. Coordinates outside Bulgaria's Natural Earth boundary are rejected before the payment is processed.
Example use cases
Agricultural soil suitability assessment
“I'm evaluating farmland near Plovdiv, Bulgaria — can you check the coarse-fragment volume in the top 5 cm of soil at latitude 42.13, longitude 24.71 so I know how rocky the topsoil is?”
Environmental site characterization
“We're running an environmental survey at coordinates 43.20 latitude, 27.92 longitude in Bulgaria. Can you pull the SoilGrids coarse-fragment content for the 0-5 cm layer there?”
Precision agriculture data enrichment
“For a precision agriculture project in the Danube plain — can you get me the topsoil coarse-fragment percentage at 43.85 latitude, 25.97 longitude in Bulgaria?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/bg-soil-coarse-fragmentsWhen to prefer
Choose this endpoint when you need point-based SoilGrids coarse-fragment volume specifically for the Bulgaria geographic extent and require the 0–5 cm surface layer. It is ideal for Bulgarian agricultural, environmental, or land-use workflows that need cost-effective per-call pricing via x402. Use sibling endpoints on the same host for other Bulgarian soil or terrain metrics.
Side effects
- Coordinate outside Bulgaria's Natural Earth boundary — request rejected before payment
- Latitude or longitude out of the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Invalid or missing coordinate fields — schema validation error
- Service unavailable or upstream SoilGrids data unreachable — HTTP 5xx error
