{"jsonrpc":"2.0","id":1,"method":"tools/list"}list_collections — List GovInfo collections (BILLS, CFR, USCODE, FR, CHRG, CRPT, HMAN, PLAW, SERIALSET, USCOURTS, etc.) with package counts. Use the collection code with search_packages to filter.search_packages — Full-text + faceted search across GovInfo. Filter by one or more collection codes (BILLS, FR, CFR, USCODE, CHRG, CRPT, CREC, PLAW, USCOURTS...), date range, congress, and free-text query. Several codes search the union of those collections. Returns package IDs, titles, collection and issue dates.get_package — Metadata for a single package by packageId (e.g., "BILLS-118hr1234ih", "FR-2024-05-12"). Returns title, dates, citations, granule count, download links (PDF/XML/MODS).list_granules — List granules within a package — e.g., sections of a CFR title, individual entries in a Federal Register issue. Returns granule IDs + titles.get_granule — Fetch summary metadata for a single granule (sub-unit) within a GovInfo package, given package_id and granule_id (both from list_granules). Returns title, class, and provenance fields from the GovInfo summary endpoint.gao_red_book — Find the chapter of GAO's Principles of Federal Appropriations Law — the Red Book — that governs a federal appropriations, fiscal-law or government-funding question, described in plain words. Answers questions about what an appropriation may lawfully be spent on (the purpose statute and the necessary expense rule), how long it stays available (the bona fide needs rule, expired and cancelled accounts, no-year and multi-year money), how much may be obligated (the Antideficiency Act, augmentation, miscellaneous receipts, apportionment), recording valid obligations, continuing resolutions and funding lapses, accountable-officer liability and relief, grants and cooperative agreements, guaranteed and insured loans, acquisition, real property, and claims for and against the government. Returns the ranked chapters together with the full table of contents, each row naming which EDITION it comes from: GAO publishes the Red Book chapter by chapter, so the current treatise is a mix of Fourth and Third Edition chapters and this reads that composition live from GAO on every call. Every row carries the chapter PDF, its source_last_modified and age_days. This is official interpretation by the agency that decides federal appropriations law, not statute — pair it with uscode or cfr text for the underlying provision.gao_comptroller_decisions — Search Comptroller General decisions and opinions — the B-numbered rulings in which GAO decides federal appropriations and fiscal-law disputes, the precedent the Red Book itself cites. Give a topic in plain words (purpose statute violation, augmentation of appropriations, gift acceptance authority, improper payment, interagency agreement) and get the decisions, each with its B-number, decision date and GovInfo package. Filters out GAO audit and performance reports so the result set is decisions only, and reports how many of the underlying hits were decisions. Complements gao_red_book (the treatise) and gao_protests_search (bid-protest decisions, a different GAO docket).Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
