This is a comprehensive reference for working with HeyGen's AI avatar video API. It covers everything from basic authentication and quota management to advanced features like real-time streaming avatars and video translation. The skill breaks down the API into logical chunks: core video generation with avatars and voices, customization options like backgrounds and text overlays, and integration patterns including webhooks and Remotion. What stands out is the practical organization, separating foundation concepts from advanced features, which makes it easy to find what you need whether you're making your first avatar video or building complex multi-scene workflows with custom photo avatars.
