}🟢get_incidents(region, category, groups, minSeverity, q, ...)
Merged live incidents from all feeds plus manual reports. Filter by region key, category, group, severity, source, or bbox. Results come from a shared ~15-minute snapshot; real-time refresh requires an API key with that entitlement (details: cityalert.live/developers).
