The Bulletin service one of the first core Network Services. It provides real-time broadcasting of information across the network, enabling a reliable means of disseminating up-to-date information such as events, service provisions or important news.
The service understands a couple of filters:
Limit the number of bulletins in the response (e.g. limit=5)
Only respond with bulletins that have specified tags (e.g. tags=network)
Only respond with bulletins that are of the specified category (e.g. categories=Events)
