# Wowza Video REST API server response caching

Some Wowza Video REST API endpoints return a cached response if you make
a duplicate `GET` request to the endpoint within a specified period of
time. We recommend you make requests to these endpoints no more
frequently than the specified cache time, since the data returned will
be unchanged.

The following table shows specific endpoints and the amount of time
responses are cached for `GET` requests to that endpoint.

| Endpoint | Cache time (seconds) |
|  --- | --- |
| /assets/* | 1 |
| /assets_tags | 1 |
| /live_streams | 1 |
| /live_streams/state | 1 |
| /recordings | 1 |
| /schedules | 1 |
| /stream_sources | 1 |
| /stream_targets | 1 |
| /transcoders | 1 |
| /transcoders/state | 1 |
| /metrics/* | 5 |
| /transcoders/ID/uptimes/ID/metrics/current | 5 |
| /transcoders/ID/uptimes/ID/metrics/historic | 5 |
| /live_streams/ID/stats | 10 |
| /transcoders/ID/stats | 10 |
| /usage/*  Exception: /usage/*/live | 60  1 |
| /analytics/viewers/* | 10 - If the time range queried is less than 60 minutes. 60 - If the time range queried is 60 minutes or greater. |
| /analytics/engagement/vod_streams/{id} | 10 - If the time range queried is less than 60 minutes. 60 - If the time range queried is 60 minutes or greater. |
| /analytics/popularity/* | 10 - If the time range queried is less than 60 minutes. 60 - If the time range queried is 60 minutes or greater. |
