eBook Store API Integration

I’m ready to turn PageVault’s lightning-fast compression API into the backbone of a multi-channel eBook storefront. The core task is to wire the existing REST endpoints so they not only shrink large publication files on the fly but also let customers purchase and download them seamlessly. Here’s what the finished solution should do: • Accept an uploader’s original EPUB, MOBI or PDF, route it through the PageVault compression service, then store the optimized asset in my cloud bucket. • Push the final, compliant files to Amazon Kindle, Apple iBooks and Google Play Books from a single dashboard, keeping each platform’s metadata requirements in mind. • Present buyers with a secure payment gateway (Stripe preferred, though I’m open to another PCI-compliant option) and deliver the correct format once payment clears. • Log every transaction and transfer so I can audit royalties and storage savings later. You can use Node.js, Python or Go—whatever fits best with the PageVault JSON API—but the code needs to be clean, well-documented and container-ready (Docker). A short README that lets me spin it up locally, plus Postman or Swagger docs for each route, will be the acceptance criteria. If you’ve connected apps to Kindle Direct Publishing, Apple Books Partner Center or Google Books Partner APIs before, that experience will help us go live faster.
