}Stream real-time swap transactions for a single pool or token
Paid plans only. Available on Dev, Pro and Enterprise keys on https://streaming-pro.dexpaprika.com; keyless requests and free keys receive HTTP 403.
Establishes an SSE stream for swap transactions on a specific pool or token using query string parameters.
Resume: each swap event has an SSE id. Send the last one back as Last-Event-ID (browsers do this on reconnect), or pass since, to get missed swaps first (last 15 minutes, up to 100).
Supported Channel Events: - pool: Swap transactions for a pool. Schema matches TransactionResponse. - token: Swap transactions involving a token. Schema matches TransactionResponse. - ping: Infrastructure keep-alive payload (PingEvent). - warning: System warning notifications (WarningEvent). - error: Stream-level operational exceptions (ErrorEvent).
