01 · Overview

What is Predexon?

Predexon provides REST, WebSocket, tick history, wallet analytics, and cross-venue data through a unified developer platform. Best for: Teams using unified REST, WebSocket, tick history, and wallet analytics to build low-latency research, backtests, terminals, or cross-venue routing systems. Less suitable for: Casual users who do not need an API or institutional data surface. Key limitations: Latency and completeness claims should be tested for the exact venue; premium streams and historical downloads have plan-specific terms.
