{"jsonrpc":"2.0","id":1,"method":"tools/list"}reg_agenda_search — Search the Unified Agenda of federal regulatory actions — every rule an agency has told OIRA it plans to propose, finalize, or has completed, since Fall 1995. Answers "what rules is EPA planning", "regulatory agenda for immigration", "upcoming FDA rulemaking on menthol cigarettes". Filter by agency (name, acronym, or code — e.g. "EPA", "Environmental Protection Agency"), a keyword against the rule title/abstract, and/or rule_stage (e.g. "Proposed Rule Stage", "Final Rule Stage", "Prerule Stage", "Long-Term Actions", "Completed Actions"). Defaults to the newest edition on file when edition is omitted. This is the LEADING record — an intent shows up here, often years before the same rule appears in eCFR or the Federal Register.reg_rin — Full detail for one Regulation Identifier Number (RIN), across EVERY Unified Agenda edition it has appeared in — proving the rule's history rather than just its latest status. Returns the abstract, agency, and one entry per edition showing how rule_stage, rin_status, and priority_category changed over time. Answers "what is RIN 2060-AV62 about", "history of this rulemaking", "has this rule stalled or progressed".reg_agency_agenda — One agency's full regulatory agenda for a given (or the newest) edition — every RIN it has open, grouped by rule_stage. Answers "what is EPA's regulatory agenda", "how many rules does DOL have in the proposed stage". Use reg_agenda_search instead when filtering by keyword or across agencies.reg_agenda_coverage — Reports which Unified Agenda editions are currently loaded — the oldest and newest edition on file, total edition count, and total RIN-edition rows. Use to gauge coverage before relying on this for a historical range or a specific edition, since the biannual backfill drains in gradually rather than loading all history from 1995 in one pass.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
