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 Poland; results outside it are rejected before payment.
Output
Returns the mean cation exchange capacity (CEC) value from SoilGrids for the 0-5 cm topsoil layer at the requested coordinate. Coordinates outside Poland's boundary are rejected before any charge is applied.
Example use cases
Agricultural soil fertility assessment
“I'm evaluating farmland near Poznań at 52.41°N, 16.93°E — can you pull the topsoil cation exchange capacity from SoilGrids for that spot in Poland so I can estimate how well it holds nutrients?”
Environmental site suitability screening
“We're assessing a potential reforestation site in Poland at coordinates 50.06 latitude, 19.94 longitude. Can you get me the mean CEC for the top 5 centimetres of soil there?”
Precision agriculture data enrichment
“I need to enrich our field records with soil data — look up the SoilGrids cation exchange capacity at the 0-5 cm depth for the Polish parcel at 54.35°N, 18.65°E.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-soil-cecWhen to prefer
Choose this endpoint when you need point-level SoilGrids CEC data specifically for locations within Poland, benefit from built-in boundary validation (so out-of-Poland queries are caught before payment), and want a low-cost ($0.004 USDC) pay-per-call model without managing SoilGrids API credentials directly. Prefer it over generic SoilGrids access when operating in an agentic x402 payment workflow targeting Polish geography.
Side effects
- Coordinate outside Poland boundary: request rejected before payment, returns boundary validation error
- Coordinate outside the broader European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation error
- Missing or malformed latitude/longitude inputs: request rejected with parameter error
- SoilGrids data unavailable for the given location (e.g. water body or urban void): may return null or no-data response
- Network or upstream SoilGrids service downtime: timeout or 503 error
