Use identifiers for ID namespaces and required selectors, coverage for Hansard date limitations, or a named reference topic for filter IDs. Follow opaque collection cursors with the same filters; use contentCursor to reconstruct an oversized selected payload.
Search Westminster bill summaries by title, House, session, sponsoring member, reference stage or bill type. Use ukparl_lookup_reference for stage/type IDs and ukparl_get_bill for complete selected records. No session or date scope is inferred. Follow collection cursors with the same filters; use contentCursor to reconstruct an oversized item.
Retrieve a Westminster bill overview or select stages, stage, publications, amendments, amendment, motions or motion. Stage/amendment/motion selections require the bill-specific billStageId from section=stages; singular amendment/motion also require itemId from their parent collection. Use amendmentId for amendment retrieval and motion.id for motions. Collection selectors paginate whole records. Statute handoff uses only actual supplied legislation.gov.uk URLs. Follow contentCursor with the original selection to reconstruct oversized records.
Find MPs and peers by name, location or constituency, party, House, and current or historical membership. currentOnly=false includes current and former members. asOf selects historical membership and accepts name only, without House, party or location filters. Search results preserve latest profile fields; retrieve sections with ukparl_get_member. Follow opaque cursors with unchanged filters and use contentCursor for oversized records.
Retrieve a member profile, roles, committee seats, official contact information, registered interests or recorded voting history. Roles without category lists available biography categories; select category to page whole periods. Interests and voting require an explicit House. Committee person IDs differ from member IDs. Voting uses native 20-row pages and reports recorded lobby and teller facts, without lifetime participation metrics. Follow collection cursors with unchanged selectors; use contentCursor to reconstruct oversized records.
Search official Commons or Lords division summaries, or use detail, voters or party_totals with a divisionId from the same House. Search supports title/number text, member and inclusive division dates; member searches include teller participation. Detail preserves complete metadata and teller identities, with roster selectors for voters mode. Voters can filter exact source party labels and House-compatible lobbies. not_recorded means only the source list, never abstention. Party totals count listed non-tellers and tellers separately from official headline counts. Follow collection cursors with unchanged filters; reconstruct oversized content using contentCursor.
Search spoken Westminster Hansard contributions by topic, member, House, date or numeric debateSectionId. Returns full source contribution text where supplied, including HTML; previews are labelled summaries. Repeat with a returned debateSectionId to search that section, which does not establish an entire debate transcript. Historical completeness is not guaranteed, including the 2004–2006 website warning despite some API records. Use ukparl_lookup_reference topic=coverage for archive guidance. Follow collection cursors unchanged and contentCursor for lossless oversized contributions; retry timeouts with shorter date windows.
Search Westminster written questions and answer previews by text, asking member, House, answering body, answer state and dates. Use mode=detail with a returned questionId for complete question and answer HTML, corrections and attachment links. A UIN is not a questionId. Search includes all sessions and withdrawn questions. Follow collection cursors unchanged; use contentCursor for lossless oversized answers.
Find Westminster committees with mode=search, then use committeeId for detail, members, inquiries or publications. Inquiries returns every committee business type, labelled by isInquiry; use businessId with mode=inquiry for complete business detail or to filter publications. Use publicationId with mode=publication for complete evidence/report document metadata and source links. Memberships retain all role periods; personId is distinct from Members API memberId. No document downloads or text extraction. Follow cursors with unchanged filters; contentCursor retrieves oversized records losslessly. Typed entities retain sourcePath relationships to reconstruct nested source metadata.
