## 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 pdf-password-unlock-api-pixo-tools-599b1cbc -d '<json body>'
```

Example prompt: I have a password-protected PDF called 'report.pdf' and the password is 'Sunshine2024' — can you unlock it and give me the unencrypted version?

## When to prefer this

Use this endpoint when you have a password-protected PDF and the correct password, and need to produce an unlocked version programmatically at a flat $0.02 per call. Prefer this over manual tools when automating document pipelines or when downstream PDF operations (OCR, extraction, merging) require an unencrypted file.

## Known failure modes

- Wrong password provided — decryption fails with an authentication error
- File is not actually password-protected — may return an error or pass-through
- Corrupted or malformed PDF input — processing error returned
- File too large or unsupported encryption scheme — error response
- Network or payment failure — x402 payment not completed

## How this service works

Remove a PDF's password (requires the password) — flat price

## Output

A decrypted, unlocked PDF file with password protection removed, ready for further reading or processing.
