	Description		Read-only	Idempotent	Open world
`convert_document`Convert a document up to 8 MB to Markdown and return it directly. Pass the file as base64 in `content_base64`, or as a download link in `file`, and its name in `filename`. The extension decides the type: .pdf, .docx, .pptx, .xlsx, .html, .htm or .txt. Returns `markdown` and `meta` (`filename`, `length` in characters). PDFs come back as plain text without headings and without OCR. For scans, tables and page numbers, use `submit_conversion_job`. Works without an API key at the anonymous rate limit. Credits: 1 per call.	Convert a document up to 8 MB to Markdown and return it directly. Pass the file as base64 in `content_base64`, or as a download link in `file`, and its name in `filename`.
