## 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-pdf-flatten-85bbb0a5 -d '<json body>'
```

Example prompt: Can you flatten this PDF so all the form fields and annotations are permanently baked in and any JavaScript is removed? Here's the URL: https://example.com/myform.pdf — use 'all' mode so everything visible gets flattened.

## When to prefer this

Choose this endpoint when you need to permanently embed PDF annotations, form data, and widget appearances into static page content, especially when security sanitization (removing JavaScript or active content) is also required. It is particularly useful for archiving filled forms, preparing PDFs for sharing with untrusted recipients, or producing print-ready static documents. Prefer it over generic PDF conversion tools when you need granular control over which annotation layers to flatten (all, screen, or print modes).

## Known failure modes

- PDF URL is not publicly accessible or resolves to a private/internal host — request refused
- PDF exceeds 20 MB (URL) or 10 MB decoded (base64) — size limit error
- Malformed or password-protected PDF — processing failure
- Neither url nor pdf_base64 provided — validation error
- Invalid base64 encoding in pdf_base64 — parse error
- Invalid mode enum value — validation 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 flattened PDF as a base64-encoded string, along with metadata including file name, byte size, page count, flatten mode used, number of annotations before and after, number of dropped widgets, number of appearances drawn, whether untrusted content was detected, and any active content (e.g. JavaScript) that was removed, plus any warnings encountered during processing.
