Introduction

Live indicative pricing, streamed continuously from TetraFi’s liquidity network.

Instead of asking for prices one at a time, subscribe once: the price feed carries continuous indicative updates from TetraFi’s solvers and LPs over a single WebSocket. Pick the corridors and size tiers you care about - and, for full-depth consumers, take per-network snapshot streams of the aggregated book.

Where It Fits

• Pre-trade sizing - screen a trade against live prices first, and spend a firm RFQ quote only once it clears your bar
• Continuous evaluation - solvers and aggregators watching TetraFi liquidity around the clock, with zero draw on quote rate limits
• A standing depth picture - aggregated LP liquidity across your routed pairs, always current

Quick Reference

Transport	WebSocket
Authentication	API key or JWT via the token query parameter
Complexity	Moderate - you manage subscriptions and decode the stream

From Connect to First Price

Stage	What happens	Result
1	Open wss://api.tetrafi.io/api/v1/ws?token=<key>	Connection established
2	Subscribe: prices:{srcChain}:{input}:{dstChain}:{output}:{tier}	Confirmation per topic
3	Listen	Price events for your corridors, best level first

Size tiers (1k, 10k, 100k, 1m) let you subscribe at the notional you actually trade - a 100k subscription prices a hundred-thousand-unit clip, not a spot midpoint. Up to 50 concurrent subscriptions per connection.

See the Reference for pricing modes and expiry behavior.
