Varosity Documentation
Your agent. Your accounts. Every model.
Varosity is an API for video, voice, music, and image generation, designed to be called by AI agents. This documentation covers everything your agent (and you) need: API reference, MCP server setup, CLI usage, provider configuration, and skills for coding agents.
