HeyGen API (Deprecated)
This skill is deprecated. Use the focused skills instead: - `create-video` — Generate videos from a text prompt (Video Agent API) - `avatar-video` — Build videos with specific avatars, voices, scripts, and scenes (v2 API)
This skill remains for backward compatibility but will be removed in a future release.
AI avatar video creation API for generating talking-head videos, explainers, and presentations.
Tool Selection
If HeyGen MCP tools are available (mcp__heygen__*), prefer them over direct HTTP API calls — they handle authentication and request formatting automatically.
| Task | MCP Tool | Fallback (Direct API) |
|---|---|---|
| Generate video from prompt | mcp__heygen__generate_video_agent | POST /v1/video_agent/generate |
| Check video status / get URL | mcp__heygen__get_video | GET /v2/videos/{video_id} |
| List account videos | mcp__heygen__list_videos | GET /v2/videos |
| Delete a video | mcp__heygen__delete_video | DELETE /v2/videos/{video_id} |
If no HeyGen MCP tools are available, use direct HTTP API calls with X-Api-Key: $HEYGEN_API_KEY header as documented in the reference files.
Default Workflow
Prefer Video Agent for most video requests. Always use prompt-optimizer.md guidelines to structure prompts with scenes, timing, and visual styles.
With MCP tools:
- Write an optimized prompt using prompt-optimizer.md → visual-styles.md
- Call
mcp__heygen__generate_video_agentwith prompt and config (durationsec, orientation, avatarid) - Call
mcp__heygen__get_videowith the returned video_id to poll status and get the download URL
Without MCP tools (direct API):
- Write an optimized prompt using prompt-optimizer.md → visual-styles.md
POST /v1/video_agent/generate— see video-agent.mdGET /v2/videos/<id>— see video-status.md
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
