x402
HALOWERK Central Land – Czechia Soil Cation Exchange Capacity (0-5 cm) is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-13).
Returns the mean SoilGrids cation exchange capacity (CEC) for the 0–5 cm soil layer at a given coordinate validated to fall within Czechia.

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 Czechia; results outside it are rejected before payment.
Output
A numeric mean cation exchange capacity value (cmolc/kg) for the 0–5 cm soil layer at the queried coordinate, derived from SoilGrids data. Coordinates outside the Czechia boundary polygon are rejected before any charge is applied.
Example use cases
Farm soil fertility assessment
“I'm evaluating a field near Olomouc — can you pull the mean soil cation exchange capacity for the 0–5 cm layer at latitude 49.59, longitude 17.25? I want to know how well the topsoil holds nutrients.”
Environmental site screening
“We're doing a pre-development soil check near Brno. Can you get the SoilGrids CEC reading for the top 5 cm at coordinates 49.19 latitude, 16.61 longitude in Czechia?”
Agricultural research data collection
“I need topsoil cation exchange capacity values for several Czech locations — start with latitude 50.76, longitude 15.05 near Liberec and give me the mean CEC for the 0 to 5 centimetre layer.”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/cz-soil-cecWhen to prefer
Choose this endpoint when you need point-level topsoil CEC data specifically for locations within Czechia, sourced from the SoilGrids global dataset. It is ideal for agricultural analysis, land-use planning, or environmental modelling workflows that require a lightweight, pay-per-call lookup rather than bulk raster downloads. The built-in Czechia boundary validation ensures you only pay for valid in-country queries.
Side effects
- Coordinate outside Czechia boundary — request rejected with an error before payment is processed
- Latitude or longitude out of the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing required latitude or longitude field — schema validation failure
- SoilGrids data unavailable for the queried pixel — null or error response
