# Caladan API

At [Caladan](https://caladan.xyz/), we believe that accessing digital asset liquidity should be seamless, fast, and tailored. Our Caladan API is built for crypto prime brokers, custodians with active trading desks, broker-dealers and neobrokers embedding crypto, RFQ-enabled exchanges, FX brokers adding crypto execution, and on/off-ramp providers.

This site describes the **Financial Information eXchange (FIX) protocol** used by Caladan’s liquidity taker gateway with no-touch bilateral spot trading (perpetuals coming soon). The Caladan API ensures low latency, deterministic execution, and consistent market access.
