congressgov_enacted_laws Browse enacted public and private laws from Congress.gov by congress and law type ('pub' for public laws, 'priv' for private). 'list' filters by enactment status and law type — the discovery path 'bill_lookup' does not offer. 'get' returns the origin bill record (sponsor, actions, summaries, text),
congressgov_member_lookup Discover congressional members and their legislative activity. No name search. For 'list', filter by stateCode (optionally with district), by congress, or by both together (e.g., 118th Congress + CA, or CA district 12 in the 118th). Add currentMember=true to restrict to currently serving members. On
congressgov_committee_lookup Browse congressional committees and their legislation, reports, and nominations. Committee codes follow the pattern chamber-prefix (h/s/j) + abbreviation + 2-digit number — use 'list' (with optional 'filter' for name→code resolution) to discover codes, then 'get' or drill into 'bills', 'reports', or

Set 'chamber' to 'house' (default, from the Congress.gov API) or 'senate' (from the Senate's official LIS feed). Use 'list' to find votes by congress and session (newest first by default), 'get' fo
congressgov_senate_nominations Browse presidential nominations to federal positions and track the Senate confirmation process. Use 'list' to browse, 'get' for nomination detail, 'actions'/'committees'/'hearings' for confirmation pipeline data, or 'nominees' to retrieve individual appointees in a multi-nominee batch. Nominations u

The fromDateTime/toDateTime filters apply to the summary's update time, not the bill's action date, so results includ
congressgov_crs_reports Browse and retrieve CRS (Congressional Research Service) reports — nonpartisan policy analyses by subject-matter experts at the Library of Congress, covering policy areas, legislative proposals, and legal questions. Report IDs use letter-number codes (e.g., R40097, RL33612, IF12345). Use 'list' to b
congressgov_committee_reports Browse and retrieve committee reports from Congress.gov — reports accompany legislation reported out of committee and explain the bill's purpose, committee amendments, dissenting views, and the committee vote.

congressgov_daily_record Browse the daily Congressional Record — floor speeches, debates, and legislative text published each day Congress is in session. Navigation is hierarchical: volumes (via 'list') → issues (via 'issues') → articles (via 'articles'). Use 'list' to find recent volumes, 'issues' to see what's in a volume
