Data Stream Builder
Use this page to see the real public stream before you write code for it. Start with simple presets, narrow the filter to the pools and event types you need, and check the live messages instead of guessing from docs alone.
Why this helps: you can check message format, filters, and event frequency on a free live stream before spending time on a production client. The builder keeps one socket open and updates filters with messages instead of forcing a reconnect every time.
