How this service works
Four small local tools: clean CSVs, compare exports, flatten JSON and print SKU text labels. Free previews; complete offline editions from 1 USDC, once.
Output
Returns a JSON object containing a receipt token (for download authentication), the product name ('EPUB Preflight v1.0'), and a download URL path where the full preflight report can be retrieved using the token.
Example use cases
Pre-publish EPUB validation check
“Before I upload my ebook to Amazon, can you run an EPUB preflight on it with RowPocket to catch any formatting or compatibility issues and get me the report download link?”
Indie author ebook quality check
“I just finished formatting my novel as an EPUB — can you run it through RowPocket's EPUB Preflight tool so I can see if there are any structural problems before I send it to my editor?”
Publisher batch preflight workflow
“I need to verify this EPUB file meets distribution standards — run the RowPocket EPUB Preflight check and give me the receipt token and download link for the validation report.”

Endpoint
GEThttps://rowpocket-csv-rescue.josuegrnds21.chatgpt.site/api/products/epub-preflight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, one-time-purchase EPUB validation and preflight check without a recurring SaaS subscription. It is best suited for indie authors, small publishers, or developers who occasionally need to verify EPUB correctness before distribution and want a pay-once offline-compatible tool rather than a cloud-native continuous validation service.
