Endpoint
POSThttps://api.pixo.tools/v1/pdf/protectWhen to prefer
Use this endpoint when you need to add AES-256 password protection to a PDF programmatically, especially in automated workflows where document security is required before distribution. Prefer this over client-side solutions when you need a reliable, server-side encryption step integrated into an agent pipeline. It is priced per page, making it cost-effective for smaller documents.
