# Query skill details

Read the skills in the current workspace. When the workspace to which the skill belongs is not specified, the service will first check the current workspace; if it is not found and the current workspace is not the system workspace, it will then search for the system skill with the same ID.

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

## Before you call

First [query the skill list](list-skills.md) to obtain the skill ID. Prepare a personal access token and target workspace ID that has 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`: Target workspace ID, passed through `X-Workspace-ID` Header.
- `$SKILL_ID`: The skill ID to be queried.

## Request example

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

| Parameters | Type | Is it required | Description |
| --- | --- | --- | --- |

## Query parameters
