How this service works
Mean SoilGrids coarse-fragment volume for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Finland; results outside it are rejected before payment.
Output
A numeric value representing the mean volumetric coarse-fragment content (%) of the 0–5 cm soil layer at the queried coordinate, derived from SoilGrids data. Coordinates outside Finland's Natural Earth boundary are rejected before any payment is charged.
Example use cases
Agricultural suitability screening in Finland
“I'm evaluating farmland near Tampere — can you check the coarse-fragment volume in the top 5 cm of soil at latitude 61.50, longitude 23.76? I need to know how stony the topsoil is before we decide on tillage equipment.”
Environmental impact assessment for construction
“We're planning a groundworks project in Rovaniemi at 66.50° N, 25.72° E — can you pull the SoilGrids coarse-fragment content for the 0–5 cm layer so our engineers can assess drainage and excavation risk?”
Ecological habitat modelling for Finnish forests
“I'm building a habitat suitability model for a forested area in eastern Finland — what's the mean volumetric coarse-fragment percentage in the surface soil layer at 62.89° N, 30.11° E?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/fi-soil-coarse-fragmentsWhen to prefer
Choose this endpoint when you need point-level SoilGrids coarse-fragment volume specifically within Finland, and you want boundary validation baked in before payment is charged. Prefer it over generic SoilGrids API calls when working in an agentic x402 payment workflow or when Finland-specific validation and per-call micro-pricing ($0.004 USDC) are desirable.
Side effects
- Coordinate outside Finland boundary — rejected pre-payment with a geographic validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- SoilGrids data unavailable for the exact coordinate (e.g. ocean or unmapped area) — may return null or error
- Malformed request body — 400 bad request
- Payment failure via x402 protocol — request not processed
