How this service works
Mean SoilGrids sand fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Romania; results outside it are rejected before payment.
Output
A numeric value representing the mean sand fraction (likely as g/kg or percentage) for the 0-5 cm soil depth at the queried coordinate, sourced from SoilGrids. Coordinates outside Romania's boundary are rejected before any charge is incurred.
Example use cases
Agricultural site suitability assessment
“I'm evaluating farmland near Buzău, Romania — can you check the sand fraction in the top 5 cm of soil at latitude 45.15, longitude 26.82? I want to know if the texture is suitable for drip irrigation.”
Construction foundation soil analysis
“Before we break ground on a site in Cluj-Napoca, I need to know the topsoil sand content. Can you get the SoilGrids sand fraction for 0-5 cm depth at latitude 46.77, longitude 23.59?”
Environmental research data collection
“For my ecology study, I need the mean sand fraction of the surface soil layer at several points in the Danube Delta — start with latitude 45.05, longitude 29.60 in Romania.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/ro-soil-sandWhen to prefer
Choose this endpoint when you need point-level mean soil sand fraction data specifically for locations within Romania, with built-in boundary validation ensuring you only pay for valid in-country coordinates. Prefer this over generic SoilGrids API calls when you want a pre-validated, metered microservice with x402 micropayment support and automatic rejection of out-of-bounds coordinates.
Side effects
- Coordinate outside Romania boundary: request rejected before payment with a validation error
- Coordinate within European bounding box but outside Romania: rejected by Natural Earth boundary check
- Malformed latitude/longitude values: schema validation error
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5): rejected
- Service unavailable or upstream SoilGrids data missing: server error response
- Insufficient USDC balance or x402 payment failure: payment error before data is returned
