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 Spain; results outside it are rejected before payment.
Output
A numeric value representing the mean coarse-fragment volume (percentage by volume) in the 0–5 cm topsoil layer at the requested coordinate, sourced from SoilGrids. Coordinates outside Spain's Natural Earth boundary are rejected before any payment is charged.
Example use cases
Agricultural land suitability screening
“I'm evaluating a plot near Zaragoza at 41.65° N, -0.89° W for drip irrigation farming — can you check the coarse-fragment content of the topsoil there so I know how stony it is?”
Soil data enrichment for vineyard site
“We're prospecting vineyard sites in Ribera del Duero. Can you pull the SoilGrids coarse-fragment volume for the 0–5 cm layer at 41.63 latitude, -3.69 longitude?”
Environmental baseline for reforestation project
“I need a baseline soil stoniness value for a reforestation site in Andalusia at 37.39 N, -5.99 W — specifically the coarse-fragment percentage in the surface soil layer.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/es-soil-coarse-fragmentsWhen to prefer
Choose this endpoint when you need point-level coarse-fragment volume data for the surface soil layer (0–5 cm) specifically within Spain, with built-in boundary validation so out-of-country coordinates are rejected before billing. Prefer it over generic SoilGrids API calls when you want a pay-per-query microservice with automatic Spain-boundary enforcement. Use sibling endpoints on the same host for sand fraction, CEC, or texture class at the same coordinate.
Side effects
- Coordinate outside Spain's Natural Earth boundary — request rejected, no charge
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing required latitude or longitude parameter — schema validation error
- Payment failure or insufficient USDC balance — transaction not completed
- Temporary upstream SoilGrids data unavailability — service error
