Omitted settings try direct access first and automatically use managed Netherlands residential access when needed. This can add Apify Proxy platform usage costs; Actor result pricing is unchanged. Explicit useApifyProxy: false without custom URLs stays direct, and explicit null retains direct access.

An explicit empty object retains the SDK managed-proxy defaults. A proxy cannot unlock age-restricted, login-only or unavailable profiles.
