lookup_provision | Look up a CFR provision by citation (e.g. "21 CFR 1304.04") or by an exact quotation, optionally as of a past date. Returns the provision text with a ProvisionEvidence object (source, snapshot date, hashes). Explicitly reports ambiguity or no-match instead of guessing. Requires a free API key. |
get_provision_history | Documented change history for a CFR provision by canonical id (e.g. "21-cfr-1304.04(a)"): before/after text, computed redline, observed dates, and candidate final rules. 404 when the provision is not in the documented-change set — absence of a documented change is not a claim that nothing changed. N |
rules_amending | Which final rules amend a CFR part or section, read from each rule's own amendatory instructions ("Amend § 52.2120 by..."). Returns the rules, the sections each addresses, and dates. This reports what a rule SAYS it amends — it is not an attribution of any observed text change to that rule. Covers 2 |
recent_cfr_changes | Most recent detected changes to CFR text (title, part, name, dates), newest first. No API key required. |
get_stats | Aggregate corpus statistics: documents, obligations, pairs, agencies, coverage dates. No API key required. |
search_regulations | Full-text search over Federal Register documents and extracted obligations (FTS5/BM25). Totals are approximate (total_exact: false). Requires an API key. |
list_rules | List Federal Register documents with filters: agency slug, document type, rulemaking pathway (interim_final/temporary/direct_final = notice-and-comment bypass classes), or docket id. Requires an API key. |
list_obligations | List extracted regulatory obligations ("who must do what") with filters: agency, deontic class, free text. Obligations are machine-extracted with quality tiers; they are not legal advice. Requires an API key. |
get_requirement | Detail for one extracted obligation by id, including its source rule and citation URL. Requires an API key. |
get_rule_comments | Public comments for a Federal Register document (organization, title, date, body where available). Coverage is partial and stated in the response. Requires an API key. |
