How this service works
Mean SoilGrids clay 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 value representing the mean clay fraction (as a percentage or volume fraction) in the 0-5 cm topsoil layer at the specified Bulgarian coordinate, derived from SoilGrids data. Coordinates outside Bulgaria's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Crop suitability assessment for Bulgarian farmland
“I'm evaluating a plot near Plovdiv at 42.1354° N, 24.7453° E — what's the clay content in the top 5 cm of soil there so I can assess if it's suitable for wheat?”
Site selection for construction foundation
“We're considering a building site in Bulgaria at coordinates 43.2141° N, 27.9147° E — can you check the topsoil clay fraction at 0-5 cm depth to help with foundation planning?”
Environmental soil monitoring in Bulgaria
“For our land degradation study, pull the SoilGrids clay fraction for the 0-5 cm layer at 41.9022° N, 25.5551° E in the Rhodope region of Bulgaria.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/bg-soil-clayWhen to prefer
Choose this endpoint when you need point-level SoilGrids clay fraction data specifically within Bulgaria's national boundary at the 0-5 cm depth. It is preferable to a generic SoilGrids API wrapper when you need built-in boundary validation for Bulgaria, pay-per-call pricing via x402, and the convenience of a single-purpose endpoint without managing authentication or large dataset downloads.
Side effects
- Coordinate outside Bulgaria's Natural Earth boundary — request rejected, no charge applied
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing or malformed latitude/longitude parameters — schema validation error
- Payment failure or insufficient USDC balance — 402 response
- No SoilGrids data available for the requested coordinate — null or error response
