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 AES-256 encrypted PDF as a base64-encoded string, along with the file name, byte size, page count, content type, the permissions that were applied, input/output byte sizes, and flags indicating whether an owner password was set and whether active content was removed.

Example use cases

Lock confidential contract before sharing

“I need to protect this confidential contract PDF before emailing it to the client — here's the URL: https://storage.example.com/contract.pdf. Set the user password to 'Client2024!' and turn off the ability to copy text or modify the document.”

Restrict student exam PDF permissions

“Please encrypt this exam PDF so students can open it with the password 'ExamDay2025' but cannot print it, copy text from it, or annotate it — the file is at https://school.example.com/exam_final.pdf.”

Protect invoice PDF with owner controls

“I want to lock down this invoice PDF with AES-256 encryption. The PDF is base64-encoded — here's the data: [base64string]. Set the user password to 'InvoiceOpen' and the owner password to 'AdminOverride99' so only I can lift the restrictions later.”

Endpoint

When to prefer

Choose this endpoint when you need server-side AES-256 PDF encryption with fine-grained permission controls (print, copy, annotate, assemble, fill forms, accessibility) without setting up local PDF tooling. Ideal for AI agents that need to secure documents on the fly before delivery. Prefer this over client-side solutions when the PDF is already hosted at a public URL and you want a pay-per-call model with no infrastructure overhead.

Side effects

PDF URL is inaccessible, private, or IP-literal host — returns error refusing the URL
PDF exceeds 20 MB via URL or 10 MB via base64 — rejected with size error
Neither url nor pdf_base64 provided — missing required input error
Invalid base64 encoding in pdf_base64 — parse error
user_password not provided — required field missing error
Password exceeds 127 characters — validation error
Malformed or non-PDF file submitted — processing error

Input

Schema · Request body

Field	Type	Description
url	—	Public http(s) URL of the PDF (at most 20 MB; private, internal and IP-literal hosts are refused); or use pdf_base64.
output	string	base64 (default): the file comes back inline as base64. url: the file is stored for 24 hours and the reply carries a download link (url, expires_at, bytes, content_type, sha256) instead of the base64, which keeps the file out of your context window.
pdf_base64	—	The PDF as base64 (at most 10 MB decoded per request); or use url.
permissions	object	What a user-password holder may do (default: everything).
user_password	string	Needed to open the PDF; never logged.
owner_password	—	Lifts the restrictions; default: a random one nobody knows.
