What is Predictefy?
Predictefy combines a trader workspace with developer infrastructure. It normalizes market and order-book data, matches related outcomes across venues and exposes price-gap research, history replay and paper trading. The pricing page gives concrete API limits even though parts of the landing page still invite users to an API waitlist.
