How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Romania; results outside it are rejected before payment.
Output
A numeric value representing the mean total nitrogen (from SoilGrids) for the 0–5 cm topsoil layer at the queried coordinate. The coordinate is validated against Romania's Natural Earth boundary; requests outside Romania are rejected before payment is processed.
Example use cases
Farmland soil fertility assessment
“I'm evaluating a plot of farmland near Cluj-Napoca — can you pull the topsoil total nitrogen for coordinates 46.77 latitude, 23.59 longitude in Romania?”
Precision agriculture nutrient mapping
“I need the SoilGrids total nitrogen reading for the 0–5 cm layer at lat 44.43, lon 26.10 in Romania so I can plan fertilizer application for the season.”
Environmental research data collection
“For my land degradation study, can you get me the mean soil nitrogen value at 47.15 latitude and 27.58 longitude in Romania?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/ro-soil-nitrogenWhen to prefer
Use this endpoint when you need SoilGrids total nitrogen data specifically for a point location within Romania at the 0–5 cm depth layer. It is ideal for precision agriculture, land valuation, soil health monitoring, or environmental research workflows targeting Romanian coordinates. It is not suitable for coordinates outside Romania or for other soil properties (use sibling endpoints for CEC, silt fraction, or slope metrics).
Side effects
- Coordinate outside Romania boundary — request rejected before payment, error indicating invalid location
- Coordinate within European coverage range but outside Romania — boundary validation failure
- Malformed latitude or longitude values outside WGS84 European bounds (lat 34–72.5, lon -31.5–40.5) — schema validation error
- No SoilGrids data available for the queried point — null or missing data response
- Payment failure via x402 protocol — call not processed
