Estimate & Sync
Audience-size estimate
Meta only today - returns available: false (not an error) for every other platform so callers can branch cleanly rather than treating it as a failure. Uses the same targeting-resolution logic as a real campaign launch, so the estimate reflects exactly what would be sent to Meta. Requires scope ads:read.
