How this service works
Mean SoilGrids pH in H2O 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 soil pH value (H2O method) for the 0–5 cm topsoil layer at the queried coordinate, sourced from SoilGrids. Coordinates outside Bulgaria's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Vineyard site soil acidity check
“I'm scouting a potential vineyard plot near Plovdiv — can you look up the topsoil pH at latitude 42.15, longitude 24.75 so I know if the acidity is right for grape cultivation?”
Precision agriculture field mapping
“I need the SoilGrids pH reading for the top 5 cm of soil at latitude 43.41, longitude 25.63 in Bulgaria — it's part of a fertiliser recommendation workflow for a cereal farm.”
Environmental land classification
“Can you get the soil pH value for the 0 to 5 cm layer at coordinates 41.98 latitude, 25.10 longitude in Bulgaria? We're classifying land parcels for a conservation project.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/bg-soil-phWhen to prefer
Use this endpoint when you need a point-level topsoil pH value (0–5 cm, H2O) for a coordinate known to be within Bulgaria. It combines SoilGrids scientific data with pre-payment boundary validation, making it efficient for Bulgarian-scoped agricultural, environmental, or land-use workflows where you want to avoid paying for out-of-bounds queries.
Side effects
- Coordinate outside Bulgaria boundary — request rejected before payment, error indicating invalid location
- Coordinate within European bounding box but outside Bulgaria — rejected by Natural Earth boundary check
- Malformed or missing latitude/longitude — validation error returned
- Coordinate at sea or non-land area — may return error or null result
- Service unavailable — upstream SoilGrids data not reachable
