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 Spain; results outside it are rejected before payment.
Output
A numeric value representing the mean cation exchange capacity (CEC) of the 0–5 cm soil layer at the queried coordinate, derived from SoilGrids data. The coordinate must fall within Spain's Natural Earth boundary; requests outside this boundary are rejected before any charge is applied.
Example use cases
Agricultural soil fertility assessment
“I'm evaluating farmland near Zaragoza — can you look up the soil cation exchange capacity at 41.65° N, 0.89° W? I need the SoilGrids CEC for the surface layer.”
Environmental site suitability screening
“We're planning a reforestation project in Andalusia. Can you check the topsoil CEC at 37.38° N, 5.97° W to help us understand nutrient retention at that site?”
Land valuation data enrichment
“I'm building a soil quality profile for a parcel in Valencia — fetch me the mean cation exchange capacity for the 0–5 cm layer at 39.47° N, 0.37° W.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/es-soil-cecWhen to prefer
Use this endpoint when you need a reliable, pay-per-call lookup of soil CEC specifically within Spain, backed by SoilGrids data. It is ideal for agents doing per-parcel soil quality assessments, agricultural planning tools, or land enrichment pipelines that require the 0–5 cm surface layer CEC without needing to integrate directly with the SoilGrids API. Prefer this over generic geospatial APIs when Spain-scoped soil chemistry data is the specific requirement.
Side effects
- Coordinate outside Spain's Natural Earth boundary — request is rejected before payment with a geographic validation error
- Latitude or longitude outside the accepted European range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Missing or malformed coordinate parameters — returns a 400-level error
- SoilGrids data unavailable for the specific coordinate (e.g. coastal/maritime edge cases) — may return null or error response
