HALOWERK Southern Land – Spain Soil Bulk Density (0-5 cm)

Use this endpoint when you need authoritative SoilGrids bulk density data specifically for locations within Spain, and want coordinate validation (rejecting non-Spanish points) built into the service before any payment is charged. Prefer it over generic soil APIs when you need per-point topsoil (0-5 cm) bulk density values with micropayment-per-call pricing via x402.

• Coordinate outside Spain boundary — request rejected before payment with a geographic validation error
• Latitude or longitude out of published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
• Invalid or missing coordinate fields — returns input validation error
• Endpoint unavailable or network timeout — HTTP 5xx or connection error
• Coordinate within European bounding box but outside Spain — rejected by Natural Earth boundary check
