+## Room History
+
+The Room History API lets you browse your rooms that ended in the last 60 days. For each room, you can see which peers had issues, such as high round trip time or packet loss, and how their bitrate, packet loss, and round trip time changed over time. All requests go to `https://fishjam.io/api/v1/public`.
