 ### Run live query
 
-Run one or more live queries against the specified hosts and responds with the results
-collected after 25 seconds.
+> This updated API endpoint replaced `GET /api/v1/fleet/queries/run` in Fleet 4.43.0, for improved compatibility with many HTTP clients. The [deprecated endpoint](https://github.com/fleetdm/fleet/blob/fleet-v4.42.0/docs/REST%20API/rest-api.md#run-live-query) is maintained for backwards compatibility.
 
-If multiple queries are provided, they run concurrently. Response time is capped at 25 seconds from
-when the API request was received, regardless of how many queries you are running, and regardless
-whether all results have been gathered or not. This API does not return any results until the fixed
-time period elapses, at which point all of the collected results are returned.
+Runs a live query against the specified hosts and responds with the results.
 
-The fixed time period is configurable via environment variable on the Fleet server (eg.
-`FLEET_LIVE_QUERY_REST_PERIOD=90s`). If setting a higher value, be sure that you do not exceed your
-load balancer timeout.
+If some targeted hosts haven't responded, the live query will stop after 25 seconds (or whatever time period is configured), and all collected results are returned.
 
-> WARNING: This API endpoint collects responses in-memory (RAM) on the Fleet compute instance handling this request, which can overflow if the result set is large enough.  This has the potential to crash the process and/or cause an autoscaling event in your cloud provider, depending on how Fleet is deployed.
+The timeout period is configurable via environment variable on the Fleet server (e.g. `FLEET_LIVE_QUERY_REST_PERIOD=90s`). If setting a higher value than the default, be sure not to exceed your load balancer timeout.
