• openstates_get_event
  Fetch full event detail by OCD event ID. Returns agenda, participants, media links, and associated documents when requested via include. Experimental — event coverage is limited in Open States. Obtain the event_id from openstates_search_events.

• openstates_get_jurisdiction
  Fetch full metadata for a specific jurisdiction including all legislative sessions, their identifiers, and coverage dates.
