WebSockets

Construct the state of the order book and stream executed orders in real-time.

Paxos offers secure, real-time market and execution data feeds via public WebSocket connections that provide a number of advantages when compared to the v2 API:

  • Real-time event notifications.
  • Minimized data transfers over the network.
  • Reduced latency when compared to a polling strategy.

Once a secure (wss://) connection is established, each feed begins streaming data.

  • The Market Data Feed provides event-driven updates for the entire order book or for a single market.
  • The Execution Data Feed provides event information for all markets or for a single market.

Connection Details​

Paxos provides unauthenticated connections for two environments. Production data feeds are suitable for general use. Sandbox data feeds are intended for testing.

Production Data Feeds​

wss://ws.paxos.com/marketdata
wss://ws.paxos.com/marketdata/{market}
wss://ws.paxos.com/executiondata
wss://ws.paxos.com/executiondata/{market}

Sandbox Data Feeds​

wss://ws.sandbox.paxos.com/marketdata
wss://ws.sandbox.paxos.com/marketdata/{market}
wss://ws.sandbox.paxos.com/executiondata
wss://ws.sandbox.paxos.com/executiondata/{market}
note

All data feeds have a built-in, instantaneous failover. Clients should have a reconnection mechanism in case of server disconnection.

Available Markets​

The public feeds may contain inactive markets or markets unavailable for trading. Availability varies depending on the environment. For example, we may enable a market in the Sandbox environment for testing but not in Production. Some Paxos Accounts have additional trading restrictions in Production.

tip

Get Order Book retrieves a list of markets available for trading and List Recent Executions retrieve a list of all platform trades. However, these endpoints are not suitable for streaming order book and execution event data.
