## 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-pdf-unlock-91cdad53 -d '<json body>'
```

Example prompt: I have a password-protected PDF at https://example.com/report.pdf — can you unlock it using the password 'MySecret123' and give me the decrypted file?

## When to prefer this

Use this endpoint when you need to programmatically unlock a password-protected PDF and have the password available. Prefer this over manual decryption tools when operating in an automated pipeline, especially when the PDF must be fetched from a URL or supplied as base64. It is ideal for agent workflows that receive encrypted PDFs and need to access or extract their content.

## Known failure modes

- Wrong password provided — PDF cannot be decrypted, error returned
- PDF URL is unreachable or returns a non-PDF response
- PDF exceeds 20 MB (URL) or 10 MB decoded (base64) size limit
- PDF is not actually password-protected (no-op or error)
- Malformed base64 input causing decode failure
- Network timeout when fetching PDF from remote URL

## 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 the decrypted PDF binary (or base64 representation), with all password protection removed, ready for reading, extraction, or further processing. The response is the unlocked PDF file itself.
