## 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 relaystation-pdf-bookmarks-3f351522 -d '<json body>'
```

Example prompt: Can you read the bookmark tree of this PDF and give me the full outline as JSON so I can see its chapter and section structure before I start extracting content?

## When to prefer this

Use this endpoint when you need to understand a PDF's document structure — chapters, sections, subsections — before deciding which parts to extract. It is ideal as a first step in multi-stage PDF processing pipelines, for verifying document completeness, or for building navigation interfaces. Prefer this over full-text extraction when you only need the outline, not the content.

## Known failure modes

- PDF has no bookmarks or outline — returns empty or null tree
- PDF is password-protected or encrypted — access denied error
- Malformed or corrupted PDF — parse failure
- PDF URL is inaccessible or times out — network error
- Input body missing required fields — validation error

## How this service works

$0.001/call. Read a PDF's outline/bookmark tree as JSON — navigate structure before extracting. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

A JSON representation of the PDF's bookmark/outline tree, including section titles, nesting levels, and page references — essentially the document's navigational skeleton for use in further extraction or display.
