How this service works
Mean SoilGrids clay fraction 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 clay fraction (as a proportion or percentage) of the 0–5 cm soil layer derived from SoilGrids data for the specified coordinate. Coordinates outside the Portugal boundary (validated against Natural Earth) are rejected before payment is processed.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a farm plot near Évora, Portugal — can you tell me the clay fraction in the top 5 cm of soil at latitude 38.57, longitude -7.91? I need to know if it's suitable for olive cultivation.”
Construction site soil texture check
“We're planning a small building project near Faro — what's the clay content in the surface soil layer at latitude 37.02, longitude -7.93? We need it to assess drainage and foundation risks.”
Environmental research data collection
“For my study on soil texture variability in the Douro Valley, can you fetch the 0–5 cm clay fraction at coordinates latitude 41.15, longitude -7.80 in Portugal?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-soil-clayWhen to prefer
Choose this endpoint when you specifically need surface clay fraction data (0–5 cm depth) for a location within Portugal, especially when you need boundary-validated results and are comfortable with micropayment-per-call pricing. It is ideal for precision agriculture, land assessment, environmental research, or construction planning workflows that require authoritative SoilGrids-sourced clay data. Prefer it over generic soil APIs when Portugal-specific boundary enforcement and per-call pay-as-you-go pricing are desirable.
Side effects
- Coordinate outside Portugal boundary — request rejected before payment, returns boundary validation error
- Latitude or longitude out of accepted European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed or missing coordinate fields — input validation error
- SoilGrids data unavailable for remote or coastal edge coordinates — may return null or no-data response
- Network or provider timeout — transient error, retry recommended
