How this service works
Mean SoilGrids clay fraction 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 clay fraction (as a percentage or proportion) for the 0–5 cm soil layer at the submitted coordinate, derived from SoilGrids data. Returns an error if the coordinate falls outside the validated Spain boundary.
Example use cases
Vineyard site soil assessment
“I'm evaluating a plot for a vineyard near Córdoba — can you check the clay fraction in the top 5 cm of soil at latitude 37.85, longitude -4.80?”
Agricultural drainage planning
“We're designing drainage for a field in Valencia at lat 39.47, lon -0.38 — what's the clay content in the 0–5 cm soil layer there?”
Construction ground suitability check
“Before we break ground on a site in Madrid at latitude 40.42, longitude -3.70, can you pull the mean topsoil clay fraction to assess soil plasticity?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/es-soil-clayWhen to prefer
Choose this endpoint when you need point-level topsoil clay fraction data specifically for locations within Spain, and want boundary validation before incurring payment costs. Prefer it over generic SoilGrids API wrappers when you need a pay-per-call microservice with built-in Spain geofencing and no API key setup.
Side effects
- Coordinate outside Spain boundary — request is rejected before payment is processed
- Latitude or longitude outside the declared European coverage range (34–72.5°N, -31.5–40.5°E) — validation error
- Malformed or missing coordinate fields — schema validation error
- Payment failure via x402 protocol — request not fulfilled
- SoilGrids upstream data unavailable — service error
