 Subscribers can retrieve the current `seq` with the `Lp-Trickle-Seq` metadata (HTTP header). This is useful in case `-1` was used to initiate the subscription; the subscribing client can then pre-connect to `Lp-Trickle-Seq + 1`
 
+GET `/channel-name/next` returns the next segment seq as plain text in the response body and in the `Lp-Trickle-Latest` response header.
+If the channel does not exist, the server returns 404.
+If the channel is closed, the server also includes `Lp-Trickle-Closed: terminated`.

 Subscribers can initiate a subscribe with a `seq` of -N to get the Nth-from-last segment. (TODO)
 
 The server should send subscribers `Lp-Trickle-Size` metadata to indicate the size of the content up until now. This allows clients to know where the live edge is, eg video implementations can decode-and-discard frames up until the edge to achieve immediate playback without waiting for the next segment. (TODO)
