HALOWERK Baltic Land – Estonia Drainage Tendency

Choose this endpoint when you need a terrain-derived surface runoff tendency score specifically for a point location within Estonia. It is ideal for hydrological risk assessment, land-use planning, construction site evaluation, or agricultural drainage analysis where slope and ruggedness are the key inputs. Prefer it over generic elevation APIs when you need a processed drainage tendency metric rather than raw elevation data, and over broader European services when you specifically need Estonia-validated results with boundary enforcement.

• Coordinate outside Estonia boundary — rejected with an error before payment is processed
• Coordinate outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation failure
• Malformed or missing latitude/longitude — schema validation error
• Point over water or border ambiguity — may be rejected by boundary check
• Payment failure via x402 protocol — call not executed
