      "description": "Create a narrated video lesson from a document, text or web page (use when someone wants a document turned into a training, safety or procedure video)\n\nUse when the user brings a document, a block of text or a web page and wants a video, a lesson, an explainer or a summary video of it. Accepted sources: a file (PDF, DOCX, PPTX, MD or TXT, max 50 MB) sent as multipart, which the local MCP server takes as `file_path`; plain `text` (max 5 MB); or a public http(s) `url` whose readable text becomes the document. Every on-screen sentence cites the source paragraph it came from, so use this when the user needs traceable training, safety or procedure videos. Narration is Turkish. Returns a lesson id immediately; nothing renders and no minutes are spent until approve_lesson. Follow it with get_lesson until the storyboard needs approval. With an Idempotency-Key the same request inside 24h returns the same lesson (same key, different body is 409). API documentation: https://zipirapp.com/en/api/",
