Text-to-Speech (HeyGen Starfish)
Generate speech audio files from text using HeyGen's in-house Starfish TTS model. This skill is for standalone audio generation — separate from video creation.
Authentication
All requests require the X-Api-Key header. Set the HEYGEN_API_KEY environment variable.
curl -X GET "https://api.heygen.com/v1/audio/voices" \
-H "X-Api-Key: $HEYGEN_API_KEY"
Tool Selection
If HeyGen MCP tools are available (mcp__heygen__*), prefer them over direct HTTP API calls.
