# Query the agent that references this skill

Lists the agents in the current workspace that are effectively bound to the specified skill. The response only contains a summary of the agent display and does not return the full definition of the agent.

```text
GET https://moi.matrixorigin.cn/newmoi/workspaces/{workspace_id}/skills/{skill_id}/referencing-agents
```

## Before you call

First [query the skill list](list-skills.md) to obtain the skill ID. Prepare the personal access token, target workspace ID, and skill ID that have access to the target workspace.

The example below uses:

- `$AI_STUDIO_API_KEY`: The actual personal access token, passed through the `X-API-Key` Header.
- `$WORKSPACE_ID`: Query the current workspace ID of the reference relationship, passed through the `X-Workspace-ID` Header.
- `$SKILL_ID`: The referenced skill ID.

## Request example

```bash
curl "https://moi.matrixorigin.cn/newmoi/workspaces/$WORKSPACE_ID/skills/$SKILL_ID/referencing-agents?limit=20" \
  -H "X-API-Key: $AI_STUDIO_API_KEY" \
  -H "X-Workspace-ID: $WORKSPACE_ID"
```

## Path parameters

| Parameters | Type | Is it required | Description |
| --- | --- | --- | --- |
| `workspace_id` | string | Yes | Query the current workspace ID of the reference relationship. |
| `skill_id` | string | Yes | The skill ID being referenced. |

## Query parameters

| Parameters | Type | Is it required | Description |
| --- | --- | --- | --- |
| `skill_workspace_id` | string | No | The workspace to which the skill belongs; can only be the current workspace or `system`. When not provided, if the skill is not found in the current workspace, it will continue to search for system skills. |
| `limit` | integer | No | Quantity per page. Default `50`, maximum `200`. |
| `cursor` | string | No | `next_cursor` returned from the previous page. Cursors must be used with the same workspace and skill set. |

## Successful response

Returns `200` on success. If there is still data later, use `next_cursor` to query the next page.

```json
{
  "code": 0,
  "data": {
    "items": [
      {
        "id": "agent_01",
        "workspace_id": "ws_01",
        "name": "数据助手",
        "status": "active"
      }
    ],
    "limit": 20,
    "next_cursor": "cursor_01"
  }
}
```

The response fields are as follows.

| Field | Type | Description |
| --- | --- | --- |
| `code` | integer | `0` on success. |
| `data.items` | array | A summary of the agent display that references this skill. |
| `data.items[].id` | string | Agent ID and workspace. |
| `data.items[].workspace_id` | string | Agent ID and workspace. |
| `data.items[].name` | string | Agent name and status. |
| `data.items[].status` | string | Agent name and status. |
| `data.limit` | integer | The actual page size used by this page. |
| `data.next_cursor` | string | Next page cursor; does not return when there is no more data. |

`[]` after a type denotes an array. `[]` in a field path denotes each item in an array.
