# List widgets

> Every widget in a workspace, with its hostname and agent binding. Filter by agent to find what serves it.

The embeddable surfaces in a workspace. Each row carries a `state`, the agent binding in `spec`, and (with `includeInfo`) the hostname and agent name in `info`.

<CodeGroup>
  ```typescript TypeScript theme={null}
  const widgets = await client.widgets.list({ workspaceId, includeInfo: true });

  for await (const w of widgets) {
    console.log(w.metadata.name, w.state, w.info?.host);
  }
  // Acme Support  STATE_ACTIVE  k7m2xq9fp4wn.widgets.cadenya.com
  ```

  ```go Go theme={null}
  page, err := client.Widgets.List(ctx, cadenya.WidgetListParams{
  	WorkspaceID: cadenya.String(workspaceID),
  	IncludeInfo: cadenya.Bool(true),
  })
  if err != nil {
  	panic(err.Error())
  }

  for _, w := range page.Items {
  	fmt.Println(w.Metadata.Name, w.State, w.Info.Host)
  }
  // Acme Support  STATE_ACTIVE  k7m2xq9fp4wn.widgets.cadenya.com
  ```

  ```ruby Ruby theme={null}
  page = cadenya.widgets.list(workspace_id: workspace_id, include_info: true)

  page.auto_paging_each do |w|
    puts([w.metadata.name, w.state, w.info&.host].join("  "))
  end
  # Acme Support  STATE_ACTIVE  k7m2xq9fp4wn.widgets.cadenya.com
  ```

  ```bash cURL theme={null}
  curl "https://api.cadenya.com/v1/workspaces/${WORKSPACE_ID}/widgets?includeInfo=true" \
    -H "Authorization: Bearer ${CADENYA_API_KEY}"
  ```
</CodeGroup>

## Filtering

`agentId` narrows the list to widgets bound to one agent, in either the canonical `agent_…` form or the `external_id:<value>` form. `labels` and `sortOrder` behave as they do on every list endpoint, and `limit` sets a page size the SDK iterator pages past on its own.

```typescript theme={null}
const bound = await client.widgets.list({
  workspaceId,
  agentId: 'external_id:refund-decider',
});
```

That is the question to ask before deleting an agent: which widgets stop working.

## `includeInfo` costs rate limit

`info` carries `dnsLabel`, `host`, the bound agent's name, and `createdBy`. Populating it counts more against your rate limit, so ask for it when you display the list, not when you poll it.

        BareMetadata contains the minimal metadata for a resource: the ID and an
         optional human-readable name. These are used for reference fields where the
         full metadata (account scoping, timestamps, labels, external IDs) is not
         needed — e.g., the tool references inside an agent variation spec or the
         tools assigned to an objective. Both fields are server-populated; clients
         provide IDs through sibling fields rather than by constructing a
         BareMetadata themselves.
