action_since
, updatedsince, and createdsince date filters for change-tracking
id
takes OCD person IDs and returns exactly those people, so it needs no jurisdiction alongside it. It resolves the IDs that search results, openstatesgetbill sponsorships, and openstatesgetcommittee memberships hand back — several in one call, since upstream /people accepts id repeatedly and offers no
include
parameter requests sponsorships, actions, votes, abstracts, versions, and related bills inline — eliminates follow-up openstatesgetbill calls for most research workflows
jurisdiction.classification
separates the tiers: "state" is a state legislature, "country" is the US Congress. currentrole.orgclassification does not — it is upper/lower for a US Senator exactly as for a state senator
openstates_get_bill
Fetch full detail for a specific bill by OCD ID or three-part path (jurisdiction + session + billid)
openstates_get_committee
Fetch committee detail by OCD organization ID, with optional membership roster
openstates_get_event
Fetch full event detail including agenda, participants, and media links
openstates_get_jurisdiction
Fetch full metadata for a specific jurisdiction including all legislative sessions and their identifiers
openstates_get_legislators_by_location
Find every legislator representing a geographic coordinate (latitude/longitude) — state legislators and the federal delegation
openstates_list_jurisdictions
List all 56 jurisdictions (50 states, DC, and 5 US territories) covered by Open States with session identifiers and coverage metadata
openstates_search_bills
Search state legislative bills across all covered US jurisdictions with full-text search, jurisdiction/session filtering, subject tags, and sponsor lookups

openstates_search_events
Search hearings, floor sessions, and committee meetings (experimental)
openstates_search_people
Search state legislators and officials within a jurisdiction by name, chamber, or district, or fetch specific people by OCD person ID
org_classification
targets a role type: upper (Senate), lower (House/Assembly), executive (governors and executive officials), legislature (every legislator — both chambers merged into one paginated set, all upper members then all lower)
stateCount
and federalCount report the split, and the rendered text labels each legislator's tier
