HeyGen API
AI avatar video creation API for generating talking-head videos, explainers, and presentations.
Default Workflow
Prefer Video Agent API (POST /v1/video_agent/generate) for most video requests.
Always use prompt-optimizer.md guidelines to structure prompts with scenes, timing, and visual styles.
Only use v2/video/generate when user explicitly needs:
- Exact script without AI modification
- Specific voice_id selection
- Different avatars/backgrounds per scene
- Precise per-scene timing control
- Programmatic/batch generation with exact specs
