How this service works
$0.001/page. Password-protect a PDF with 256-bit AES and set permissions. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny
Output
Returns an encrypted PDF binary protected with 256-bit AES encryption, with the specified password and permission restrictions applied. The output file is a valid PDF that requires the password to open and enforces the configured access permissions.
Example use cases
Secure a confidential contract before sending
“Please encrypt this contract PDF with the password 'Contract#2024' and lock it so it can only be read — no printing, no editing, no copying.”
Protect employee payslip PDFs
“I need to password-protect this payslip PDF with the password 'HR_Private9!' and restrict all permissions except viewing.”
Lock a report for client delivery
“Can you apply 256-bit AES encryption to this quarterly report PDF using the password 'ClientQ4_2025' and allow printing but block any editing?”
Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/pdf/encryptWhen to prefer
Choose this endpoint when you need to programmatically encrypt PDFs with strong 256-bit AES security and granular permission controls (read, print, edit, copy) in an agentic workflow. It is billed per-page at $0.001 with a 1¢ x402 minimum, making it cost-efficient for small documents. Prefer this over client-side PDF libraries when you need a stateless, serverless encryption step with no infrastructure to maintain.
Side effects
- Invalid or corrupt PDF input returns an error
- Missing password field causes request rejection
- Unsupported PDF version or DRM-already-applied file may fail
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Oversized PDF may exceed per-call limits
