Keyline API pricing
Usage-based. You pay for pages you index, questions you ask, and storage you keep.
$50 in free credit with Public Preview access, roughly 800 pages indexed with room for a few hundred questions.
Indexing is charged per page on first registration, and again when you update a document. It is a one-time cost per page: asking the same library a thousand questions afterward reuses the index.
Storage is prorated daily and includes the index alongside the file. Volume credit packs and annual pricing are available for larger libraries.

A large first import takes real time. A thousand-page library is a coffee, a fifty-thousand-page library is most of a day. Scope your first index to a subset that answers a real question, then widen it.
