HALOWERK Eastern Land – Hungary Soil Coarse-Fragment Volume (0–5 cm)

Use this endpoint when you need point-level SoilGrids coarse-fragment (rock fragment) volume specifically for locations within Hungary at the 0–5 cm depth interval. It is preferable when you want a pre-validated, pay-per-call lookup with built-in Hungary boundary enforcement, avoiding the overhead of querying SoilGrids directly and handling geographic validation yourself.

• Coordinate outside Hungary boundary — rejected with a validation error before any charge
• Coordinate within European coverage bounds but outside Hungary polygon — boundary check failure
• Latitude or longitude outside the stated European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
• Missing or malformed latitude/longitude fields — request rejected
• Service unavailable or SoilGrids data gap — may return null or error for sparse data areas
