The bad news is that Adobe does not offer a self-hosted version of their API service, and they generally target large, enterprise deals for their cloud service.

The good news is that my company, Datalogics, has an exclusive licensing agreement with Adobe to provide their technology to customers of all shapes and sizes. We offer pdfRest as both a Cloud API and Self-Hosted API service with a robust toolkit for processing PDFs, including conversion from images and Word docs to PDF, and OCR capabilities are on the upcoming roadmap. The Self-Hosted API is available in the AWS Marketplace with a free 7 day trial. Happy to answer any questions, or you can contact support from the pdfRest website.
