HALOWERK Nordic Land – Iceland Surface Soil Nitrogen
x402
HALOWERK Nordic Land – Iceland Surface Soil Nitrogen is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).
Returns the mean total nitrogen concentration (g/kg) in the 0–5 cm soil layer for a given coordinate within Iceland, sourced from SoilGrids.

How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Iceland; results outside it are rejected before payment.
Output
A numeric value representing the mean total nitrogen concentration (g/kg) in the 0–5 cm soil layer at the requested coordinate, derived from SoilGrids global soil data, returned only if the coordinate falls within Iceland's Natural Earth boundary.
Example use cases
Farm soil fertility assessment
“I'm evaluating agricultural land near Selfoss, Iceland — can you pull the mean topsoil nitrogen for latitude 63.93, longitude -20.99 so I can assess its fertility potential?”
Environmental baseline survey
“I need to establish a soil nitrogen baseline for a nature reserve in northern Iceland at lat 65.68, lon -18.10 — can you get the SoilGrids total nitrogen value for the 0–5 cm layer there?”
Geospatial data enrichment pipeline
“For my dataset of Icelandic field plots, start with the first point at latitude 64.45, longitude -22.15 — what is the mean total nitrogen in the surface soil layer according to SoilGrids?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/is-soil-nitrogenWhen to prefer
Choose this endpoint when you need authoritative SoilGrids-derived total nitrogen data specifically for Iceland surface soils (0–5 cm), especially in agentic pipelines that require per-point micropayment via x402. It is Iceland-scoped and boundary-validated, making it more reliable than calling a generic soil API without geographic enforcement. Prefer it over broader European soil endpoints when your query is definitively inside Iceland and you want the boundary check as a safeguard.
Side effects
- Coordinate outside Iceland boundary — request rejected before payment even if within broader European coverage bounds
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing required latitude or longitude field — schema validation failure
- SoilGrids backend unavailable or returning no data for the queried cell — service error
