• congressgov_bill_lookup≈ 2354 tokens

  Browse and retrieve U.S. legislative bill data from Congress.gov. Discover bills by filtering on congress, bill type, and date range — there is no keyword search. Use 'list' to browse (requires congress, defaults to most-recently-updated first), 'get' for full bill detail (sponsor, policy area, CBO estimates, law info), or drill into a specific bill with 'actions', 'amendments', 'cosponsors', 'committees', 'subjects', 'summaries', 'text', 'titles', or 'related' (each requires congress + billType + billNumber). 'text' lists the published versions and their format URLs; 'content' then reads one version's actual text, a bounded character window at a time. 'summaries' takes an optional versionCode selector and returns each row's text a bounded character window at a time — a row past the window carries textTotalCharacters/textTruncated/textNextOffset, and characterOffset reads on from there.

  • limit · integer · optionnel
    Results per page (1-250).
  • order · string · optionnel · recent | oldest
    Sort order for 'list' (sorts by update date). 'recent' (default) is newest first; 'oldest' is ascending. Ignored by other operations.
  • format · string · optionnel · text | xml
    Document format for 'content'. 'text' is GPO's Formatted Text — plain, pre-formatted print output, published for every document checked. 'xml' prefers United States Legislative Markup and falls back to Formatted XML; it exists on some bill text versions and on no committee report or Congressional Record article. PDF is not retrieved — read one at the format URLs 'text'/'articles' return.
  • offset · integer · optionnel
    Pagination offset.
  • billType · string · optionnel · hr | s | hjres | sjres | hconres | sconres | hres | sres
    Bill type code. Required for get and sub-resource operations.
  • congress · integer · requis
    Congress number (e.g., 118, 119).
  • operation · string · requis · list | get | actions | amendments | cosponsors | committees | subjects | summaries
    Which data to retrieve.
  • billNumber · ? · optionnel
    Bill number. Required for get and sub-resource operations. Accepts the digit-string form list rows carry (e.g. "9479") as well as a number.
  • toDateTime · string · optionnel
    End of date range filter (ISO 8601). Same field semantics as fromDateTime.
  • versionCode · string · optionnel
    Which summary version 'summaries' returns — the versionCode a summary row carries ('00' introduced, '49' public law). Selection runs over the bill's whole summary list, which Congress.gov publishes no filter for, and limit/offset then page the matching rows. Omit to return every version. Ignored by other operations.
  • fromDateTime · string · optionnel
    Start of date range filter (ISO 8601). Filters by the bill's update date — when Congress.gov last touched the record — not by the bill's latest legislative action.
  • characterLimit · integer · optionnel
    Maximum characters to return (1-100000) — for the document window on 'content', and for each row's summary text on 'summaries'. Legislative documents run past a million characters and an enacted bill's summary past two hundred thousand, so either takes several windows.
  • characterOffset · integer · optionnel
    First character to return, 0-based — of the document on 'content', and of every returned row's summary text on 'summaries'. Offsets are exact and are never snapped to a section or paragraph break, so feeding back the response's nextOffset (or a summary row's textNextOffset) walks the whole text with every character returned exactly once.
  • textVersionIndex · integer · optionnel
    Which text version 'content' reads, 0-based against the same order 'text' returns — 0 is the most recent version. Ignored by other operations.

• congressgov_bill_summaries≈ 1284 tokens

  Browse recent CRS (Congressional Research Service) bill summaries — plain-language summaries of bills at each legislative stage, useful for answering "what's happening in Congress?". The fromDateTime/toDateTime filters apply to the summary's update time, not the bill's action date, so results include recently rewritten summaries of older bills. Defaults to summaries updated in the last 7 days. Each item shows both the bill's action date and the summary update date. A page stops adding rows once it reaches a fixed response-character budget, and a summary longer than the per-row window arrives as an exact character window carrying textTotalCharacters/textTruncated/textNextOffset; pagination.nextOffset continues the page and a row's textNextOffset continues its text. For summaries of one specific bill — and to read a windowed summary to the end — use congressgov_bill_lookup with operation='summaries' instead.

• congressgov_committee_lookup≈ 1462 tokens

  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 'nominations' ('nominations' is Senate-only). 'get' and sub-resources only need committeeCode (chamber is inferred from the prefix); pass chamber explicitly to override. The 'bills' sub-resource defaults to 'recent' order (newest update-date first); pass order='oldest' for ascending update-date order. Upstream omits bill titles from the 'bills' sub-resource — rows carry only {congress, billType, billNumber, actionDate, relationshipType, url}; chain 'congressgov_bill_lookup get' per row to retrieve titles and policy area.

• congressgov_committee_reports≈ 1829 tokens

  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. Report types are 'hrpt' (House), 'srpt' (Senate), and 'erpt' (Executive). 'text' lists the published format URLs; 'content' then reads the report's actual text, a bounded character window at a time.

• congressgov_enacted_laws≈ 1292 tokens

  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), with the public/private law citation on the bill's 'laws' array (e.g. {"number":"118-2","type":"Public Law"}).

  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 use 'PN' (Presidential Nomination) numbering. Most nominations carry confirmation activity on the parent (e.g., PN1000); multi-part parents (e.g., PN851) carry no activity of their own — their actions, committees, hearings, and nominees live on partitioned children (PN851-1, PN851-2, …). 'get' on a parent that has no `nominees` array signals the partitioned form is needed for everything below it.
