Two modes: pass html directly to export ad-hoc content, OR pass session_id to export the session's current state. Format options: 'docx' (default, native Open XML, best for programmatic processing or mail merge), 'pdf', 'html', 'markdown', or 'txt' ('doc' is a legacy Word-compatible HTML alias). Fidelity is the differentiator vs naive HTML to docx converters. ## OpenAPI ````yaml /openapi.json post /v1/documents/export openapi: 3.1.0 info: title: Universal Document AI API description: AI-powered document editing with multi-tenant organization support version: 2.0.0 servers: [] security: [] paths: /v1/documents/export: post: tags: - v1 - mcp summary: >- Export the current document as a styled .docx (default), .pdf, .html, .md, or .txt file with full fidelity. description: >- Round-trips the document through the original docx renderer, preserving tables, borders, shading, alternating row colors, headers, footers, fonts, inline styling, and embedded images.

Backward-compat notes: - Top-level ``filename`` is retained for legacy clients that sent only ``{ html }`` and relied on the filename being auto-extracted from the first

. New clients should use ``options.filename`` — options.filename wins when both are set. - ``format`` defaults to "docx". Legacy callers passing format="doc" explicitly keep working during a short back-compat window.
