## 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 tanod-pdfpeek-set-outline-a1beb2a4 -d '<json body>'
```

Example prompt: Take this PDF at https://example.com/report.pdf and replace its bookmarks with a 2-level outline: 'Introduction' on page 1, 'Chapter 1: Setup' on page 3 (with children 'Installation' on page 4 and 'Configuration' on page 7), and 'Conclusion' on page 20.

## When to prefer this

Choose this endpoint when you need to programmatically set, replace, or clear the bookmark outline of an existing PDF without rebuilding the document from scratch. It is ideal when the PDF already exists (hosted or in memory) and you only need to modify its navigation structure. It also sanitizes active content (XFA, JavaScript), making it useful when clean, safe output is required alongside outline manipulation. Prefer it over full PDF-generation pipelines when the document content itself is unchanged.

## Known failure modes

- PDF URL exceeds 20 MB or is unreachable — error returned
- PDF URL points to a private/internal host or IP-literal — refused
- base64 payload exceeds 10 MB decoded — error returned
- Outline tree exceeds 1,000 total items or 8 levels deep — validation error
- Page number in bookmark exceeds actual PDF page count — error returned
- Both url and pdf_base64 omitted or both provided — ambiguous input error
- Malformed base64 string — decode error

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns a JSON object containing the modified PDF as a base64-encoded string (content_type: application/pdf), along with metadata: file name, input and output byte sizes, page count, outline depth, total outline item count, whether the PDF was replaced, and a report of any active content removed (e.g. XFA forms, JavaScript). The PDF is sanitized during processing.
