# Delta Feed - New Version

```
/feed/odds?revision={lastUpdatedTime}
```

Contains live sport data updates. Delivered in the form of "deltas" - differences from the previous state.

`revision` - Unix timestamp of last successfully processed delta message. Can be `0` for initial connection but we recommend using **Unix timestamp for the last 1 hour** to reduce load.

Upon connecting you will receive a set of "Snapshot" delta messages, containing full state of event.

{% hint style="warning" %}
The stream connection is rate-limited and there can be only 1 active connection at a time.
{% endhint %}

Rate limit configuration is the following:

* Connection attempt without revision - 5 connections per 1 hour
* Connection attempt with too small revision - 5 connections per 1 hour
* Connection attempt with proper revision - 5 connections per 5 minutes
