How this service works
Mean SoilGrids total nitrogen 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 value representing the mean total nitrogen concentration in the 0–5 cm topsoil layer (sourced from SoilGrids) for the queried coordinate. The coordinate is validated against France's Natural Earth boundary; requests falling outside France are rejected before any charge is incurred.
Example use cases
Agricultural site soil fertility check
“I'm evaluating a plot near Lyon — can you pull the topsoil nitrogen level for latitude 45.75, longitude 4.83? I need to know if the soil has enough nitrogen for crop farming.”
Environmental impact baseline assessment
“We're doing a pre-development environmental baseline near Bordeaux. What's the mean soil nitrogen for the 0 to 5 cm layer at latitude 44.83, longitude -0.58?”
Precision agriculture nutrient mapping
“For our vineyard planning near Reims, can you get the surface soil nitrogen reading at latitude 49.25, longitude 4.03 so we can decide on fertilisation strategy?”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/fr-soil-nitrogenWhen to prefer
Use this endpoint when you need a fast, pay-per-call lookup of topsoil total nitrogen for a specific point coordinate inside France, backed by SoilGrids data. Prefer it over bulk datasets when you need individual-point queries with geographic boundary enforcement and no subscription overhead. It pairs well with sibling endpoints (organic carbon, CEC, slope, land cover) on the same platform for comprehensive land assessment.
Side effects
- Coordinate outside France boundary – request rejected before payment, likely 422 or 400 error
- Latitude or longitude out of published European coverage range (lat 34–72.5, lon -31.5–40.5) – validation failure
- Invalid input types or missing required fields – schema validation error
- SoilGrids data unavailable for sparse or coastal grid cells – may return null or error
- Payment failure via x402 protocol – request not processed
Input
