How this service works
Mean SoilGrids organic carbon for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Portugal; results outside it are rejected before payment.
Output
Returns the mean soil organic carbon value from SoilGrids for the 0–5 cm depth layer at the specified coordinate, expressed as a numeric measurement. The coordinate is pre-validated against the Natural Earth boundary for Portugal; requests outside Portugal are rejected before any payment is processed.
Example use cases
Agricultural land quality assessment
“Can you pull the soil organic carbon data for my farmland in the Alentejo — it's at latitude 38.05, longitude -7.88? I need the topsoil carbon figure from SoilGrids for a land quality report.”
Carbon sequestration site scouting
“I'm evaluating a reforestation site in central Portugal at 39.6 latitude, -8.0 longitude. Can you get me the mean soil organic carbon for the 0 to 5 cm layer there?”
Environmental baseline for land purchase
“Before we finalize a land acquisition near Faro, Portugal — coordinates 37.02 latitude, -7.93 longitude — can you look up the topsoil organic carbon level from SoilGrids so we have a baseline?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-soil-organic-carbonWhen to prefer
Choose this endpoint when you need point-level soil organic carbon data specifically within Portugal, backed by the authoritative SoilGrids dataset. It is ideal for agricultural assessments, environmental baselines, carbon accounting, and land-use analysis where only the 0–5 cm topsoil layer is needed. Prefer it over generic soil APIs when Portugal-boundary validation is required before incurring costs, or when you need SoilGrids-sourced values rather than satellite-derived proxies.
Side effects
- Coordinate outside Portugal's Natural Earth boundary — request is rejected before payment with a boundary validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Missing required latitude or longitude parameters — 400 bad request
- SoilGrids data unavailable for the exact location (e.g. water body, no-data pixel) — null or error response
- Payment failure via x402 protocol — request not fulfilled
