How this service works
Mean SoilGrids cation exchange capacity for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for France; results outside it are rejected before payment.
Output
A numeric mean cation exchange capacity value (in cmol+/kg or equivalent SoilGrids units) for the 0–5 cm soil layer at the queried coordinate, derived from the SoilGrids dataset. Coordinates outside France's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Agricultural land due diligence
“Before we finalize purchasing that farmland in the Loire Valley, can you pull the topsoil cation exchange capacity at latitude 47.42, longitude 0.68? I want to know how well that soil holds nutrients.”
Precision farming soil assessment
“I'm planning crop rotations for my fields near Toulouse — can you get me the mean CEC for the 0–5 cm soil layer at latitude 43.60, longitude 1.44?”
Environmental site screening
“We're evaluating a brownfield site in Brittany for remediation. Can you check the surface soil CEC at latitude 48.11, longitude -1.68 to understand the soil's cation retention capacity?”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/fr-soil-cecWhen to prefer
Choose this endpoint when you need authoritative SoilGrids CEC data specifically for locations within France, especially for agricultural assessment, land valuation, or soil fertility analysis. It is more suitable than a generic soil API when you need pay-per-query pricing without subscription overhead and need the boundary validation guarantee that ensures you are querying within France.
Side effects
- Coordinate outside France boundary — request rejected before payment with a boundary validation error
- Latitude or longitude out of the declared European coverage range (34–72.5°N, -31.5–40.5°E) — schema validation failure
- No SoilGrids data available for the requested location — null or missing value response
- Malformed request body — missing or invalid latitude/longitude fields
- Payment failure or x402 protocol error — request not processed
