Integration

One API Key, All Data Feeds

Data permissions auto-bind to your API Key after subscription. Pull on-demand snapshots via HTTP or subscribe to real-time push via MQTT. Your code stays the same regardless of data source.

Subscribe once, no key changes

Entitlements attach to your existing API Key the moment a feed activates — nothing to rotate or redeploy.

Pull snapshots over HTTP

Signed REST requests for quotes, bars, and option chains. Same endpoint across every market you're entitled to.

Stream live updates over MQTT

Subscribe symbols on an open session and receive tick, quote, and depth pushes as the market moves.
