Introduction - TetraFi

Subscribe once: continuous indicative updates from TetraFi’s solvers and LPs over one WebSocket, per corridor and size tier, or per-network snapshots of the aggregated book.

Where It Fits

Continuous evaluation - watch liquidity around the clock with zero draw on quote rate limits
A standing depth picture across your routed pairs

Quick Reference


Transport	WebSocket
Authentication	API key or JWT via the `token` query parameter
Complexity	Moderate - subscriptions and stream decoding are yours

From Connect to First Price

Stage	What happens	Result
1	Open `wss://api.tetrafi.io/api/v1/ws?token=<key>`	Connection established
