HALOWERK Land Compare – Topsoil Silt

Use this endpoint when you need a direct pairwise comparison of topsoil silt content between exactly two European locations. It is the right choice when the decision is binary (which of these two sites has more silt?) rather than ranking multiple sites or measuring a different soil property such as texture class or cation exchange capacity. Choose sibling endpoints for other soil attributes or for ranking more than two sites.

• Coordinates outside European coverage bounds (latitude 34–72.5°N, longitude −31.5–40.5°E) return a validation error
• Fewer or more than exactly two locations in the array causes a schema validation error
• Missing required latitude or longitude fields returns a 400 bad request
• Network or upstream data unavailability may return a 503 or timeout
• Payment not fulfilled (x402) results in a 402 Payment Required response
