What Is Kling AI Avatar API?
Kling AI Avatar API extends Kuaishou's Kling family into specialized talking-head and avatar video. The model animates a static portrait or character image from audio or text input, producing lip-synced video with natural head movement, blinking, and micro-expressions.
Combined with ElevenLabs TTS or Text to Dialogue, it enables fully AI-native video from text through to final talking-head output. Integrates with Kling 3.0 and Kling 2.6 for a complete Kuaishou video toolkit.
