avatar-video
Avatar Video
Create AI avatar videos with full control over avatars, voices, scripts, scenes, and backgrounds. Build single or multi-scene videos with exact configuration using HeyGen's /v2/video/generate API.
Authentication
All requests require the X-Api-Key header. Set the HEYGEN_API_KEY environment variable.
curl -X GET "https://api.heygen.com/v2/avatars" \
-H "X-Api-Key: $HEYGEN_API_KEY"
Tool Selection
If HeyGen MCP tools are available (mcp__heygen__*), prefer them over direct HTTP API calls — they handle authentication and request formatting automatically.
