# List a draft's versions

> A draft's version history, newest first.

Metadata only. The stored content of an old version is deliberately not
published, so this is an audit trail rather than a way to read the document
back at a point in time. `changeSummary` is whatever was supplied on the
replace that created each version.



## OpenAPI

````yaml https://api.vaquill.ai/workspace/openapi/v1.json get /v1/matters/{matterId}/drafts/{draftId}/versions
openapi: 3.1.0
info:
  title: Vaquill Legal Workspace API
  description: >-
    Organization-scoped API for driving your legal workspace from your own
    backend: matters, documents, drafting, review, compare and matrices.


    **Authentication**: `Authorization: Bearer vq_ws_...`. Credentials are
    issued by an organization owner from the automation console at `/automation`
    and are shown once. The organization is resolved from the credential and can
    never be named in a request, so there is no `organizationId` field anywhere
    in this API and sending one is refused.


    This is NOT the Vaquill Data API. That one holds a `vq_key_` credential and
    serves the public legal corpus; the two share no credential, host or
    endpoint, and sending a `vq_key_` here is refused with an error naming the
    other product.


    ## Long-running work


    Anything that costs real work answers `202` with an **operation**. Poll `GET
    /v1/operations/{operationId}` until `status` is `succeeded`, `failed` or
    `cancelled`, honouring `Retry-After` between polls. There are no webhooks,
    so polling is the only completion signal. The five statuses are `queued`,
    `running`, `succeeded`, `failed`, `cancelled`, and there is no sixth: every
    capability reports through the same envelope.


    Send an `Idempotency-Key` on any launch. A retry with the same key and the
    same body returns the FIRST operation rather than starting a second billable
    job, which is what makes recovering from a timeout free.


    ## Identifiers


    Every public id is `<prefix>_<32 lowercase hex>`, for example
    `mat_9f2c8b1e4a7d43c9b6e0f1a2c3d4e5f6`. The prefix names the resource type.
    Ids are opaque: take them from responses rather than building them, and
    never pass a bare database uuid.


    ## Lists


    Every collection answers `{data, pagination}`, never a bare array. Page with
    `limit` and `offset`, and read `pagination.total` to size a job before
    running it. `pagination.hasMore` is the reliable signal that rows remain.


    ## Errors


    Errors are RFC 9457 problem documents (`application/problem+json`),
    including for a wrong path and a wrong method. Branch on `type`; it is the
    stable identifier and it resolves to a page describing the failure. `title`
    and `detail` are written for people and may be reworded at any time. Every
    response carries `X-Request-ID`, and every error repeats it as `requestId`:
    quote it when contacting support.


    A `404` is returned identically for a resource that does not exist, one
    belonging to another organization, and one outside your installation's
    matter allowlist. That is deliberate, so the status code cannot be used to
    discover which ids exist elsewhere.


    ## Rate limits


    Limits are per credential and are set by what an operation COSTS rather than
    by its HTTP method, so a `GET` that runs a retrieval is not a read. Each
    operation's tier is fixed; a `429` carries `Retry-After`.


    | Tier | Per minute | Per hour | Per day |

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

    | `poll` | 120 | 3000 | 30000 |

    | `read` | 60 | 1200 | 15000 |

    | `write` | 30 | 600 | 5000 |

    | `launch` | 10 | 200 | 2000 |

    | `download` | 20 | 300 | 3000 |

    | `upload` | 5 | 100 | 500 |


    ## Scopes


    A credential carries an explicit scope set, chosen when it is issued. A call
    outside them is `403` with `insufficient-scope`, naming the scopes the
    operation needed. Read and run are separate throughout, so a credential can
    be allowed to read results without being allowed to spend money producing
    them.

      The one job envelope. Every long-running call answers `202` with an

      there are no webhooks. Five statuses, no synonyms.

    description: >-

  - name: Research
    description: >-
      Asking legal questions and getting grounded, cited answers. This API does
      NOT stream: an ask answers `202` and you poll the operation, then read the
      answer off the message it points at. Conversation state is kept here, so
      you hold a chat id rather than replaying a transcript. Also covers the
      matter settings behind an answer, the skills you can ask through, and the
      standalone web-research tools.
  - name: Drafting
    description: >-
      Generating, revising and exporting draft documents. Bodies come out as
      sections and go in as markdown; the editor's own format is never on the

      The organization's negotiating positions, per contract type, and the

        The stored CONTENT of an old version is not published. A version body
        would

        be a second representation of the same document with the same TipTap
        problem

        and no customer has asked to read one; `changeSummary` plus the version

        number is what makes the list useful for an audit trail.

          title: Hasmore
          description: >-
            True when rows remain beyond this window. Derived from `offset +
            len(data) < total`, so a full final page correctly reports `false`
            rather than sending you after an empty page.
          examples:
            - false
      additionalProperties: false
      type: object
      required:
        - limit

        `total` is the count of rows matching the filter, not the count
        returned,

        so a caller can size a job before running it.
