TzKT WebSocket API is one of 34 APIs that [Tezos](https://apis.io/providers/tezos/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include WebSocket, Real-Time, Subscription, Event, and SignalR. The published artifact set on APIs.io includes API documentation.

The TzKT WebSocket API uses SignalR to deliver real-time push notifications to subscribed clients. Channels cover new blocks, new and confirmed operations (filtered by sender, target, or entrypoint), big map updates, token transfers, and account balance changes. Reconnects and message back-fills are handled automatically by the SignalR client libraries available for JavaScript, .NET, Java, and Python.
