  description: "\n      The Primary API describes actions that our Frontend makes against the NovelAI backend.\n\n      In general, third-party NovelAI API users should not engage with the Primary API beyond the /ai/ routes.\n\n      Third-party API users developing user-facing applications must ask for a user's Persistent API token to continue.\n      For security reasons it is not recommended to hold a user's credentials in plaintext.\n\n      IMPORTANT: Existing and new API users must read the upcoming generation-specific documentation:\n\n      Image Generation documentation: https://image.novelai.net/docs/index.html\n      Text Generation documentation: https://text.novelai.net/docs/index.html\n    "
