Generate a PDF from a custom PdfDocument JSON descriptor. Use this for any layout not covered by generate_invoice or generate_report — e.g. resumes, contracts, certificates, presentations, or any multi-element composition. Returns base64-encoded PDF bytes. Call list_element_types first to see available elements and options.

Generate a professional invoice PDF. Accepts structured invoice data (from/to parties, line items, optional GST/tax). Returns base64-encoded PDF. Supports INR/USD/EUR/GBP currencies. Currency symbols (₹ $ € £) are guaranteed not to break away from adjacent numbers across line wraps. gst_rate on items creates a tax column — use it for any tax system (GST, VAT, sales tax). Per-item gst_rate is summed as IGST in the totals; CGST/SGST inter-vs-intra-state routing is not currently supported.

Generate a professional multi-section report PDF. Features: auto-generated TOC, per-section headings with PDF bookmarks, page-numbered footer, running header, optional tables and callout boxes per section. Returns base64-encoded PDF.

Convert a Markdown string to a PDF. Supports headings, bold/italic, strikethrough, inline code, links, ordered/unordered lists (nested up to 3 levels), GFM tables (with column alignment), GFM task lists (☑/☐), blockquotes, fenced code blocks (rendered as plain indented text — not styled monospace), and horizontal rules. For richer layouts or styled code blocks, use generate_pdf instead. Returns a base64-encoded PDF.

Returns a markdown reference of all pretext-pdf element types and their key properties. Use this before calling generate_pdf to understand what elements and options are available.

Validate a pretext-pdf document schema without rendering it. Returns immediately with all validation errors — use this as a cheap preflight check before calling generate_pdf. Each error includes a structured path, message, and optional typo suggestion.
