HALOWERK Baltic Land – Estonia Soil Coarse-Fragment Volume (0–5 cm)
x402
HALOWERK Baltic Land – Estonia Soil Coarse-Fragment Volume (0–5 cm) is a paid API for AI agents from baltikum.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).
Returns the mean SoilGrids coarse-fragment volume percentage for the 0–5 cm soil layer at a given WGS84 coordinate within Estonia.

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 Estonia; results outside it are rejected before payment.
Output
A numeric value representing the mean volumetric coarse-fragment (gravel/stones) content as a percentage in the 0–5 cm topsoil layer at the requested coordinate, derived from SoilGrids. Requests outside Estonia's boundary are rejected before any charge is applied.
Example use cases
Agricultural site suitability assessment
“I'm evaluating a farmland parcel near Tartu at 58.37°N, 26.72°E — can you tell me the coarse-fragment volume in the top 5 cm of soil there so I can judge how rocky it is for tillage?”
Construction ground survey
“We're scoping a building site in Estonia at coordinates 59.44 latitude, 24.75 longitude — fetch the SoilGrids coarse-fragment percentage for the 0–5 cm layer so we can assess surface soil stoniness.”
Environmental monitoring baseline
“I need the mean coarse-fragment volume for the 0–5 cm soil layer at 57.82°N, 27.01°E in Estonia as part of a land-cover baseline dataset I'm compiling.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/ee-soil-coarse-fragmentsWhen to prefer
Choose this endpoint when you need point-level coarse-fragment (gravel/rock) volume data specifically for Estonian locations using SoilGrids-derived values. It is preferable over general-purpose soil APIs when you require pre-validated Estonia-boundary enforcement and a low per-call cost via x402 micropayment. Use it alongside sibling endpoints (clay fraction, sand fraction, bulk density) for comprehensive soil profile analysis.
Side effects
- Coordinate outside Estonia boundary — request rejected with validation error and no charge
- Latitude or longitude out of European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Invalid or missing coordinate fields — 400-level error
- Service unavailable or upstream SoilGrids data issue — 5xx error
