# The version in use for a project

GET

/v1/tools/{toolId}/pinned

```sh
curl --request GET \
  --url https://example.com/v1/tools/example/pinned \
  --header 'Authorization: Bearer <token>'
```

Resolves the version in use for a project (or an org, or the whole workspace): the most specific pin covering it (the project, its org, then the workspace) whose version is still active, else the newest active version, the one a flow version made now would lock its tool step to. `via` says which; `pinnedScope` names the pin that matched.

## Authorizations

- **[bearerAuth](https://docs.kindgi.com/v0.5.0/reference/api.md#bearerauth)**

## Parameters

### Path Parameters

**toolId**

required

string

ToolId — dotted namespace (`acme.lookup-order`).

### Query Parameters

**projectId**

string format: uuid

The project to resolve for; omit → only the org’s pin (with `orgId`) and the workspace-wide pin apply.

**orgId**

string format: uuid

The project’s org, when it has one. A runtime may look it up from `projectId` itself.
