The work did succeed; it succeeded earlier. Two callers asking for the same matter, altitude and document set at once attach to one job. That is separate from `Idempotency-Key`, which makes ONE caller's retry free. 409 when the matter holds no finished documents, 429 when too many generations are already in flight, 503 when the guard deciding that cannot be reached. None of the three writes anything. ## OpenAPI ````yaml https://api.vaquill.ai/workspace/openapi/v1.json post /v1/matters/{matterId}/summaries 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 `_<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. `chronology:read`, `chronology:write`, `clients:read`, `clients:write`, `compare:read`, `compare:run`, `compliance:read`, `compliance:run`, `credentials:rotate`, `documents:download`, `documents:read`, `documents:write`, `drafting:read`, `drafting:run`, `exports:create`, `exports:read`, `facts:read`, `facts:run`, `matrices:read`, `matrices:run`, `matrices:write`, `matters:read`, `matters:write`, `nda:read`, `nda:run`, `operations:read`, `playbooks:read`, `playbooks:run`, `playbooks:write`, `research:read`, `research:run`, `review:read`, `review:run`, `summaries:read`, `summaries:run`, `webhooks:read`, `webhooks:write`, `workflows:read`, `workflows:run`, `workflows:write` version: 1.0.0 servers: - url: https://api.vaquill.ai/workspace description: Vaquill Legal Workspace API (production) - url: /workspace description: Vaquill Legal Workspace API (relative to the mount) security: - WorkspaceAuth: [] tags: - name: Operations description: >- The one job envelope.

There is no `force`. On the summary route that flag bypasses the already-fresh short circuit and is a straight cost lever with nothing behind it, because metering and usage caps were cut. A caller that genuinely needs a rebuild changes something the corpus hash can see. There is also no cancel operation anywhere on this capability. The web app's cancel marks the job and its summary `cancelled` and does NOT revoke the Celery task, so the worker keeps running and moves a cancelled job back to `completed` when it finishes. Publishing that would take an operation terminal and then move it, which the operation contract does not allow, and would sell a customer a control over spend that does not stop the spend.
