Overview

What the Blank Paper Validation API does

Blank Paper Validation examines an uploaded image and reports whether it is plain blank paper rather than an actual document.

It sounds trivial and it is quietly valuable. Blank or near-blank uploads are common, whether accidental or deliberate, and catching them at capture is far cheaper than letting them fail deep inside a verification pipeline.
