Tools

• ask_legal_question

  AI-generated legal answer grounded in primary sources. countryCode='US' (default) covers USC, CFR, 50-state law, and CourtListener case law. countryCode='IN' covers 31M+ Indian judgments + 23K+ acts. US-only sourcesFilter: 'all' | 'statutes_only' | 'cases_only'. Modes: 'standard' or 'deep' (multi-hop, more thorough). Pass chatHistory for follow-ups. Returns answer with numbered citations.

  shallow
• create_watch

  Subscribe to a board so a change to that source notifies you. Delivery is by webhook (HMAC-SHA256 signed) or email, fired when the source's existing refresh finds real changes -- nothing is crawled on your behalf and there is no real-time trigger. channel is immutable once set; to change it, delete and recreate.

  shallow
• delete_watch

  Delete a watch you own. Immediate and permanent, and its delivery history goes with it. To stop notifications without losing the config or history, prefer update_watch with isActive false.

  shallow
• get_act_text

  Get URLs for the full text, PDF, and HTML versions of a specific Indian act. Pass the act_id (e.g., 'IND_central_2187' for Indian Contract Act). Returns R2 CDN URLs — fetch the text/PDF content directly from those URLs.

  shallow
• get_amendments

  Get the complete amendment history for an Indian act. Returns all footnotes showing substitutions, insertions, omissions, and notes made by amending acts. Filter by section number or amendment type. Each footnote shows the amending act name and original text (if available). Use to trace how a statute evolved.

  shallow
• get_citation_network

  Traverse the citation network around a case. Returns nodes (cases) and edges (citing relationships) with treatment types (followed, distinguished, overruled). Specify direction: 'outbound' (cases this cites), 'inbound' (cases citing this), or 'both'. Set depth (1-3 hops) and limit (1-100 nodes). Useful for understanding a case's legal influence.

  shallow
• get_pricing

  Get current API credit pricing. Returns per-endpoint credit costs and credit-to-currency conversion rates (1 credit = $0.01 USD). No authentication required. Use to check costs before making API calls.

  shallow
• get_section_changes

  What our refreshes have observed changing on one section over time: when it was added, amended or removed, newest first. This is our capture history, not the publisher's -- an empty list means we recorded no change, never that the section was never amended. For the publisher's own history, read amendmentHistory on the section.

  shallow
• get_section_cited_by

  The USC and CFR sections whose text cross-references a given section: the inverse of the crossReferences already returned on a section lookup. Use to find where a definition or requirement is actually invoked, or to gauge how load-bearing a provision is across the code.

  shallow
• get_section_cross_state

  Provisions in OTHER states that address the same subject as a given state statute section, ranked by similarity. State statutes only. Use for fifty-state surveys, multi-jurisdiction compliance, or to check whether a client's home-state rule is typical or an outlier.

  shallow
• get_section_definitions

  The term definitions that govern a section, parsed from its chapter's definitions section. Use whenever a provision turns on a term of art ('covered entity', 'security', 'employer') and you need the statute's own definition rather than the ordinary meaning.

  shallow
• get_section_neighbors

  The sections immediately before and after a given section within its own chapter or code, in statutory order. Use to read a provision in context, to find a definitions or penalties sibling, or to check whether the operative language continues into the next section.

  shallow
• get_sections_batch

  Metadata for up to 50 sections in one call, by a list of act_ids. Same fields as get_us_statute_section. Use instead of looping that tool when you already hold several act_ids, for example every result of one search. Sections that are not found are skipped and not charged.

  shallow
• get_us_statute_section

  Get metadata for a specific US statute or regulation section by act_id (e.g. 'USC_T42_C21_S1983'). The act_id comes from search_us_statutes results or ask_legal_question sources. Returns citation, title hierarchy, breadcrumb, and links to HTML, PDF, and XML formats. Use before get_us_statute_section_text to preview a section.

  shallow
• get_us_statute_section_text

  Get the **full text** of a US statute or regulation section (USC or CFR) by act_id. Returns both styled HTML (with cross-references and paragraph numbering as published in the official code) and plain text. Use when you need the actual statutory language for quotation, drafting, or analysis.

  shallow
• get_watch_change_diff

  The full text of a changed section BEFORE and AFTER one specific change, as whole documents ready to diff. Only meaningful where hasDiff is true on the change list. A missing side is not an error: hasBefore and hasAfter say which text is present, so render 'diff unavailable' rather than treating null as a failure. Unlike the rest of the law-change tools this one returns section text, so check its cost before looping over a change list.

  shallow
• list_boards

  List every watchable board: a tracked corpus source such as the Federal Register, the CFR, or one state's statutes, with its refresh cadence. A board is identified by corpusType plus state (state is null for federal). Use to discover what can be subscribed to before calling create_watch.

  shallow
• list_legislation

  Browse 23,000+ Indian acts, regulations, and legislation. Use to **discover act_id values** for get_act_text and get_amendments. Filter by category (central, state, regulatory, repealed, spent), state slug, department (sebi, rbi, etc.), year range, and status (in_force, repealed, spent). Sort by year_desc, year_asc, title_asc, title_desc, or popular.

  shallow
• list_statute_divisions

  Walk the statutory hierarchy: list the child divisions (titles, chapters, parts, or sections) under any level, in statutory order. Use to browse a code structurally when you do not yet know the section number, or to enumerate everything under a chapter.

  shallow
• list_statutes_coverage

  Self-describing coverage matrix: every corpusType we hold and its per-jurisdiction section counts. Use before answering a jurisdiction question to check whether we actually cover that state and that body of law, so you can say so instead of searching a corpus that does not exist.

  shallow
• list_statutes_laws

  Catalog of the distinct bodies of law available (a state's statutes, a state's regulations, the US Code, the US Constitution, federal court rules, and so on), each with its corpusType and section count. Use to discover the corpusType values that filter search_us_statutes.

  shallow
• list_watch_changes

  What a watched source added, amended or removed: section identifier, citation, title and detection time, newest first. Metadata only, never section text. Covers the board's whole captured history, not just since you subscribed. Safe to poll: it writes nothing and cannot suppress or double-fire a delivery. Page with sinceId and the returned cursor.

  shallow
• list_watch_deliveries

  Per-attempt delivery log for one watch: status code, error and attempt number, retained 90 days. Webhook watches only -- an email-only watch always returns an empty list, because email sends are not logged per attempt. Use to debug a webhook that is not arriving.

  shallow
• list_watches

  List the board watches you own, with their board, channel, destination, active state and the outcome of the last delivery attempt. Use to find a watchId for the other watch tools.

  shallow
• lookup_case

  Get full details for a specific case by its citation. Returns comprehensive case metadata, all known citation aliases, and citation treatment statistics showing how many times the case was followed, distinguished, overruled, approved, or referred. Use after resolve_citation or search_cases_by_citation for deep case analysis.

  shallow
• quick_search

  Fast compact **Indian** legal case search returning top 3-5 results with just the essentials: title, citation, court, year, summary excerpt, and PDF link. Same boolean query syntax as search_legal_cases but returns fewer, flatter results. Best when you need a quick overview rather than detailed results.

  shallow
• resolve_citation

  Resolve any Indian legal citation format to its canonical case record. Accepts SCC, AIR, SCR, MANU, SCALE, INSC formats (e.g., '(2019) 11 SCC 706' or 'AIR 1976 SC 1207'). Returns case details and all known citation aliases/formats. Returns found=false (not an error) when citation cannot be resolved.

  shallow
• resolve_statute_citation

  Resolve a Bluebook citation string ('42 U.S.C. 1983', '16 C.F.R. 444.1', 'Cal. Code Regs. tit. 22, 76227') to the exact section, confirmed, with an official source link and the act_id. Use this whenever the user gives you a citation rather than a question -- it is far more reliable than searching for the citation text.

  shallow
• search_cases_by_citation

  Search for legal cases by citation text or case name. Use when you know part of a case name (e.g., 'Maneka Gandhi') or a partial citation. Filter by court code (SC, DEL, BOM, MAD, etc.), year range, and validity status (GOOD_LAW, OVERRULED, DISTINGUISHED, etc.). Returns up to 50 matching cases with metadata.

  shallow
• search_legal_cases

  Boolean keyword search of the **Indian** corpus. Supports AND, OR, NOT and quoted phrases. Filter by courtType (supreme_court, high_court), courtName, year range. Returns paginated results with text, citation, court, relevance score, snippet, PDF. Present only the top results, do NOT emphasize total count. Use pageSize 10 for conversational answers, 20 for exhaustive lists. For US case law, use ask_legal_question with countryCode='US'.

  shallow
• search_legislation

  Search 23,000+ Indian acts, regulations, and legislation using semantic search. Find specific statutory provisions, definitions, penalties, and procedures. Filter by category (central, state, regulatory), state, department (SEBI, RBI, TRAI, etc.), and year range. Returns relevant act sections with text excerpts, section numbers, provision type, and PDF links. Use for questions like 'What is the penalty for insider trading under SEBI Act?' or 'Definition of goods under GST Act'.

  shallow
• search_us_statutes

  Semantic search across the **United States Code (USC)** and **Code of Federal Regulations (CFR)**. Use for federal statutory and regulatory questions: SEC (Title 17), FDA (Title 21), civil rights (Title 42), tax (Title 26), etc. Filter by corpusType ('USC' | 'CFR') and titleNumber. Returns sections with citation, title hierarchy, HTML/PDF/XML links. The returned act_id (e.g. 'USC_T42_C21_S1983') feeds get_us_statute_section_text for full text.

  shallow
• test_watch

  Send a synthetic notification to a watch's destination to verify signing, outbound auth and reachability before relying on it. Test deliveries are deliberately not persisted, so they never appear in list_watch_deliveries and never move the watch's last-notified timestamp. Rate limited by a short cooldown.

  shallow
• update_watch

  Change a watch's destination, signing secret, outbound auth, or active state. Set isActive false to pause notifications while keeping the watch's config and history. The channel itself cannot be changed.
