## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability print-api-html-to-pdf-document-renderer-d81df09a -d '<json body>'
```

Example prompt: Can you generate a styled A4 PDF titled 'Q2 Sales Report' by Jane Smith, with a teal accent color (#237b65), including a heading for 'Revenue Overview', a paragraph summarizing the quarter, a bullet list of top products, and a table of monthly figures — with a footer that says 'Confidential'?

## When to prefer this

Choose this endpoint when you need to programmatically generate a clean, paginated PDF document from structured textual content (headings, paragraphs, lists, tables) without needing arbitrary HTML/CSS rendering, remote image assets, or JavaScript execution. It is ideal for reports, proposals, agendas, and data summaries where the output must be print-ready A4 or Letter format with consistent styling. Prefer alternatives if you need to render arbitrary HTML, embed images or charts, or produce non-PDF formats like DOCX or HTML.

## Known failure modes

- Missing required 'title' or 'blocks' fields returns a 422 validation error
- Blocks array exceeds 60 items returns a validation error
- Table rows exceed 200 or table has more than 12 columns returns a validation error
- Bullet list exceeds 30 items returns a validation error
- Invalid hex color format for 'accent' returns a validation error
- Payment not included or insufficient returns a 402 Payment Required error
- Title exceeds 200 characters or paragraph text exceeds 4000 characters returns a validation error

## How this service works

Turn headings, paragraphs, lists and tables into a paginated, styled A4 or Letter PDF with page numbers. No remote assets or arbitrary scripts.

## Output

Returns a binary PDF file representing the fully paginated, styled document. The PDF includes a title page area with title, subtitle, and author; body content rendered from the provided blocks (headings, paragraphs, bullet lists, tables); automatic page numbering; and the specified accent color applied to headings and structural elements.
