# One Regulations.gov docket

> A rulemaking or non-rulemaking docket from Regulations.gov: agency, type, title, abstract, the RIN when the agency entered one, when it was last modified, how many documents we hold and of which types, and the comment count when we measured it (`null` means not measured, never zero). Current state only. Unknown docket: 404, refunded.

  description: >-
    Public API for legal statutes and legislation.


    **Authentication**: Pass your API key as `Authorization: Bearer vq_key_...`
    (preferred) or in the `X-API-Key` header. Sending two different keys in one
    request is rejected with a 401.


    **Credits**: Each call costs API credits. See `GET
    /api/v1/api-credits/pricing` for the full pricing matrix.


    ## Jurisdictions


    | Jurisdiction | Coverage | `countryCode` |

    |---|---|---|

    | **United States** | USC and the Statutes at Large, the CFR and its annual
    editions, all 56 state and territory statutory codes (50 states, DC and five
    territories), state administrative regulations, court rules, federal and
    state constitutions, federal agency guidance and adjudications, the Federal
    Register, the Sentencing Guidelines and US tax treaties. | `US` |


    See the full [Coverage page](https://www.vaquill.ai/docs/api-guide/coverage)
    for the jurisdiction-by-jurisdiction breakdown, or call
    `/us/statutes/coverage` for live counts. Coverage is per (jurisdiction,
    corpusType) pair, so treat that endpoint as the authoritative list rather
    than this summary.


    ## Endpoints


    - **US Statutes**: Search and retrieve any of the corpora above with full
    text, resolve a citation to its exact section, browse the statutory
    hierarchy, read a section as it stood on a past date, and follow its change
    history, cross-references and defined terms

    - **Board Watches**: Subscribe to a corpus source and get a webhook or email
    when it refreshes with real changes (free, API key required)

    - **Pricing**: Credit costs per endpoint (no auth required)


    ## Rate limits


    Limits are enforced per API key and scale with your plan. A `429` response
    includes a `Retry-After` header.


    | Plan | Per minute | Per hour | Per day |

    |---|---|---|---|

    | Vaquill API Pro | 60 | 1,000 | 2,000 |

    | Vaquill API Business | 150 | 2,500 | 10,000 |

      Search and retrieve US primary law. Covers the United States Code and the

      and state constitutions, court rules, Federal Register rules and
      Presidential documents, federal and state agency guidance, agency
      adjudications, state Attorney General opinions, the Sentencing Guidelines

      `/us/statutes/coverage` for the live jurisdiction-by-corpusType list.


      - **Search**: Search across all USC, CFR, state, and regulatory sections

      - **Section**: Get metadata, citation, hierarchy, and source links for a

      - **Enactments**: Which state session laws a publisher's own tables list
      against a section (supported jurisdictions only, never a complete history)
  - name: US Session Laws
    description: >-
      State session laws: the acts of each legislature as they were enacted,
      chapter by chapter, before they are folded into a code. A session law is
      what the governor signs. It carries the act's own text, including the
      language it strikes and inserts, its approval and effective dates, and,
      where the publisher prints one, the code sections it changes. That makes
      it the source for "which act changed this section, and when did it take
      effect".


      Every act has a permanent `sessionLawId` (for example
      `SSL_MN_2025R_G_Y2025_C1`, Minnesota Laws 2025, regular session, chapter
      1) whether or not we hold its text, and a citation or bill number such as
      `S.F.No. 1552` is accepted where an id goes. v1 serves STATE acts only.
      Federal session laws (the Statutes at Large, `SAL_` ids) are served by
      `/us/statutes/section`, and `/us/statutes/resolve` points a session-law
      citation here.


      **Start here**: check `/us/statutes/coverage` (free) for what we hold per
      state: each jurisdiction's `sessionLaws` block lists its sessions, which
      are complete or only partly collected, and the `series` and
      `instrumentTypes` that exist. Then **List** a session or a date range to
      get ids, **Get** one act for its record, then **Body** for its text. A law
      missing from a partly collected session is a free 404
      (`session_not_fully_collected`), not proof it does not exist.


      - **List**: everything enacted in a state's session, approved in a window,
      or taking effect on a date

      - **Get**: one act by id or by citation; dates (`effectiveDates` is always
      a list), sources and the code sections it affects

      - **Body**: the act's text as printed, paged by cursor, with amendatory
      markup preserved where the publisher printed it

      - **Batch**: up to 50 ids or citations in one call, the same record as
      Get, billed per law served, with every miss listed and its reason

      - **Changes**: a sync feed of the registry over an integer cursor
      (`sinceId`): what began to be served, was corrected, withdrawn or merged


      The reverse link, from a code section to the acts a publisher's own tables
      list against it, is `GET /us/statutes/section/{actId}/enactments`.
  - name: US Rulemaking
    description: >-
      How a federal rule is made, as public records tied together by its
      Regulation Identifier Number (RIN): the semiannual Unified Agenda (every
      edition from Fall 1995), the OIRA review under Executive Order 12866, the
      Regulations.gov docket and its documents, and the Federal Register
      documents that proposed and finalised it.


      **Start here**: `GET /us/rulemaking/coverage` (free) lists what is held
      per source and whether each is fresh. Then **By RIN** for everything held
      for one rule, **Agenda history** for how its timetable moved edition by
      edition, or **Dockets** and **Documents** for the Regulations.gov side.


      Every link between sources carries its `basis` and `quality` (`verified`,
      `candidate`, `ambiguous`). A link we could not make with confidence is
      marked, never guessed, and an umbrella RIN shared by unrelated rules
      claims no proposal-to-final pairing. A comment count of `null` means not
      measured, never zero. Comment text, attachments and commenter information
      are not held or served.
  - name: Board Watches
    description: >-
      Law-change alerts. Subscribe to a **board** (a tracked corpus source,
      identified by `corpusType` plus an optional `state`) and get a webhook or
      email whenever it refreshes with real changes, naming the exact sections
      that changed. Fetch old-vs-new text for any amended section via the change
      diff.


      Boards refresh on their own existing cadence; watching one does not change
      how often it refreshes. Every endpoint here is **free**: authenticated by
      API key and rate-limited, but not credit-metered.


      See the [Law Change Alerts

        Every error (400/401/402/403/404/405/422/429/5xx) carries a `detail`

        string, e.g. `{"detail": "Insufficient API credits."}`, on every mount
        of

        the API. A 422 adds `errors`, one entry per rejected field. Some 404s
        add

        endpoint-specific diagnosis beside `detail` (the statutes section routes

        add `actId`, `reason` and `didYouMean`); treat unknown keys as optional.
