Send a small file (under about 700 KB) as base64 text and get a file_id.

Send a small file such as a logo or image inline as base64 and get a file_id to use with file_id on POST /kb/documents/import. Accepted: PDF, Word, PowerPoint, Excel, CSV, TXT, Markdown, JSON, HTML, PNG, JPG, GIF or WebP images, MP4 or MOV video, MP3, WAV or M4A audio, up to 100 MB (each knowledge base can set a lower limit). Request bodies are capped at 1 MB, so files over about 700 KB must use POST /files/upload-links instead. The real file type is read from its bytes, never from the name. Programs, SVG images, old .doc/.ppt/.xls files, Office files with macros, embedded objects or outside links, and PDFs with scripts are refused. A file is kept for 24 hours and can only be used by the same API key or connected app, with this service.
