## GET: `/api/stream`
cobalt's live render (or stream) endpoint. usually, you will receive a url to this endpoint
from a successful call to `/api/json`. however, the parameters passed to it are **opaque**
and **unmodifiable** from your (the api client's) perspective, and can change between versions.
therefore you don't need to worry about what they mean - but if you really want to know, you can
[read the source code](/src/modules/stream/manage.js).
## GET: `/api/serverInfo`
returns current basic server info.
response body type: `application/json`
