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 Portugal; results outside it are rejected before payment.
Output
A numeric value representing the mean volumetric coarse-fragment content (stones, gravel, rock fragments larger than 2 mm) as a percentage of the total soil volume in the 0–5 cm surface layer at the queried coordinate, sourced from SoilGrids. The coordinate is verified to fall within Portugal's Natural Earth boundary before the result is returned; queries outside Portugal are rejected.
Example use cases
Agricultural suitability assessment for Portuguese farmland
“I'm evaluating a plot near Évora — latitude 38.57, longitude -7.91 — for olive farming. Can you look up the coarse-fragment volume in the top 5 cm of soil there so I know how rocky it is?”
Soil data enrichment for construction site survey
“We're planning a build near Faro, at coordinates 37.01 latitude, -7.93 longitude. Can you fetch the SoilGrids coarse-fragment percentage for the surface soil layer at that spot in Portugal?”
Environmental research data collection in Portugal
“For my land degradation study, I need the mean coarse-fragment volume for the 0–5 cm soil layer at latitude 41.15, longitude -8.61 — that's a site in northern Portugal near Porto.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-soil-coarse-fragmentsWhen to prefer
Choose this endpoint when you need point-level SoilGrids coarse-fragment volume data specifically within Portugal and want boundary validation built in. It is ideal for agricultural planning, land suitability analysis, environmental research, or construction surveys in Portugal where knowing the rockiness of the surface soil layer (0–5 cm) is critical. Prefer it over generic SoilGrids API access when you want a simple, pay-per-call microservice with geographic guardrails already enforced.
Side effects
- Coordinate outside Portugal boundary: request rejected before payment is processed
- Latitude or longitude out of allowed European coverage range (lat 34–72.5, lon -31.5–40.5): validation error
- Malformed or missing coordinate fields: schema validation error
- SoilGrids upstream data unavailable: service error response
- Payment failure via x402 protocol: request not fulfilled
