Live stream of changes (Server-Sent Events) — for up to 100 addresses

Keeps the connection open and pushes new changes so you do not have to poll. Events: klar (siden, adresser, interval_ms), aendringer (adresse_id + new changes, oldest first), ping (heartbeat every 20 seconds) and genstart (siden) after 55 minutes — reopen with the siden provided. The server checks every 30 seconds. One connection counts as one call. Requires the Pro plan or higher. At most 3 concurrent streams per API key and 10 per team (stream and firehose combined); beyond that the call returns 429 rate_limit_exceeded with Retry-After before the stream opens. A connection that is not closed cleanly is released after 90 seconds at the latest.
