The selected Status and Sprint policy are revalidated under the Team lock before any row is inserted. ## OpenAPI ````yaml /openapi/davinci-public.v2.yaml post /api/v2/orgs/{orgId}/teams/{teamId}/project-cards openapi: 3.1.0 info: title: Davinci Public API version: 2.0.0 description: > Public Routing Server API contract for Davinci integrations and official SDKs. Most operations live on the canonical `/api/v2/projects` mount and accept a personal access token (`dav_ak_live_…` / `dav_ak_test_…`) or browser access token. Evaluation-run creation is the deliberate exception: it accepts only a `purpose=automation` grant issued to a running Code execution. Project membership and role are checked on every user call, and an API key is additionally bounded by the permission ceiling derived from its scopes — a key can never exceed what its owner can do, and usually does less. Collaboration operations (invitations, membership changes, ownership transfer) are deliberately absent: they require a browser session and are not part of the programmatic surface. ## Two planes Most operations are **control plane**: they run on the Routing Server, take small requests, and answer quickly. A few are **data plane**, marked `x-plane: data`, and go straight to the machine holding your project — the only practical way to move multi-gigabyte files or hold a connection open for half an hour. Data-plane operations use a different host and a different credential. Create a session on a project and it returns both: a `dataPlane.url` to send to and a short-lived `dataPlane.token` (`dav_gr_…`, a *grant*) to send with. A grant reaches exactly one project, carries no more permission than the key that minted it, expires in minutes, and dies when its session closes. It is not interchangeable with an API key in either direction. The data-plane host never names a specific machine, so a project that moves between machines mid-session stays reachable at the same URL. servers: - url: https://davinci-app.com description: Production (control plane) - url: https://davinci-app.com/data description: >- Production (data plane). Serves the operations marked `x-plane: data`, using a session's grant rather than an API key. security: - ApiKeyBearer: [] tags: - name: Projects description: >- Create, inspect, open, close, and delete projects, and manage their attached files. - name: Content description: > Read and write the objects a project is made of. These reach the running project rather than storage, so they see uncommitted work — and so they open the project if it is not already open. - name: Branches description: > Branches, commits, and the history of a single object. A commit captures the running project's state, so these operations need the branch loaded, which they arrange for the caller. - name: Sessions description: > A session opens a project, holds it open, and issues the grant that reaches the data plane. It is the programmatic equivalent of having a project open in a browser tab: while it lives, the project stays loaded. It is also where the agent lives. Send it a prompt, read its status from the session, read the transcript back, and stop a run that is going the wrong way. - name: AgentModels description: > Chat models available to your account. The returned keys are the values accepted by the session message API; availability follows your subscription, tenant, and any profile assigned to your account. - name: Tools description: > Invoke one of the agent's tools yourself, without the agent. Useful when you already know the operation you want and do not need a model to choose it — and when you want a deterministic result rather than an interpreted one. A tool is still held to the permissions of the credential invoking it, so a key cannot reach through a tool to something its scopes exclude. - name: Files description: > Data-plane file transfer. These reach your project's machine directly using a session's grant, which is what allows request bodies far larger than the control plane accepts. - name: Usage description: > What your models cost, broken down by model, project, session, or day. These read the usage ledger, which records one event per completed provider call — not your credit balance, which is `/api/v2/billing`. Usage is reported on an interval rather than per call, so a run that is still going may not be fully counted yet. Every response carries `asOf`, the moment the newest counted event was recorded, so you can see how current a total is instead of guessing. This is separate from `projects:read` on purpose: a key that reads your project data is not thereby allowed to see what you spend. - name: Evaluations description: | Lifecycle for the ephemeral target sandbox an evaluation runs against. Creation is available only to a `purpose=automation` grant issued to a running Code execution, so a sandbox always belongs to code rather than to a person's key. It returns a second, `purpose=evaluation` grant bound to the new sandbox; it never upgrades or replaces the source credential. - name: Tests description: > Asynchronously run an authored Test. The Test executes its linked Code object and applies its native evaluation criteria to derive the verdict. This is one way to start Code, not a prerequisite for anything the Code can do: the same function called directly holds the same authority. - name: Organizations description: Discover organizations available as containers for team planning. - name: Cards description: > Project-scoped agile cards, their index hierarchy, comments, tags, assignees, card dependencies, and design-object references. Project access is checked on every call; an inaccessible project is reported as not found. - name: Teams description: > Organization-scoped team boards, linked projects, workflow columns, sprints, analytics, and card placements. Team visibility is privacy preserving: inaccessible organizations, private teams, and cross-organization ids are reported as not found rather than revealing that they exist. paths: /api/v2/orgs/{orgId}/teams/{teamId}/project-cards: parameters: - $ref: '#/components/parameters/OrgId' - $ref: '#/components/parameters/TeamId' post: tags: - Teams summary: Atomically create and place a Project Card description: > Creates a Project-owned Card, optionally assigns an effective Project member, links the Project when separately authorized, and places the Card on this Team board in one transaction.

The scopes granted at issuance determine both which operations the key may call and the ceiling on the resource permissions it can exercise. Each scope family is a ladder: `projects:manage` implies `projects:write` and `projects:read`; `cards:manage` implies `cards:write` and `cards:read`; and `teams:manage` implies `teams:write` and `teams:read`. These are named API capability bundles, not blanket domain roles: `manage` exposes only the permissions enumerated for that scope and never bypasses the acting user's current role-based access. ````
