# Assistant Get API
> Retrieve details of an existing Assistant
**The Assistants API will be deprecated on 30 April.**
For new projects, we recommend using the [Agents API](/en/developer/agents-api/agent-get). The Agents API provides native Vercel AI SDK compatibility and removes custom transformations.
See the [migration guide](/en/developer/assistants-api/assistant-to-agent-migration) to learn about the differences.
Retrieves the complete configuration and details of an existing Assistant in your workspace.
Requires an API key with the `AGENT_API` scope and access to the Assistant you want to retrieve.
## Query Parameters
| Parameter | Type | Required | Description |
| ------------- | ------ | -------- | --------------------------------- |
| `assistantId` | string | Yes | UUID of the assistant to retrieve |
## Examples
### Basic Retrieval
```javascript theme={null}
const axios = require("axios");
async function getAssistant() {
const response = await axios.get(
"https://api.langdock.com/assistant/v1/get",
{
params: {
assistantId: "550e8400-e29b-41d4-a716-446655440000"
},
headers: {
Authorization: "Bearer YOUR_API_KEY"
}
}
);
console.log("Assistant details:", response.data.assistant);
}
```
## Validation Rules
The API enforces the following validation rules:
* **Assistant access** - Your API key must have access to the assistant
* **Workspace match** - Assistant must belong to the same workspace as your API key
## Response Format
### Success Response (200 OK)
```typescript theme={null}
{
status: "success";
assistant: {
id: string;
name: string;
description: string;
instruction: string;
emojiIcon: string;
model: string;
temperature: number;
conversationStarters: string[];
inputType: "PROMPT" | "STRUCTURED";
webSearchEnabled: boolean;
imageGenerationEnabled: boolean;
codeInterpreterEnabled: boolean;
canvasEnabled: boolean;
extendedThinking: boolean;
actions: Array<{
actionId: string;
requiresConfirmation: boolean;
}>;
inputFields: Array<{
slug: string;
type: string;
label: string;
description: string;
required: boolean;
order: number;
options: string[];
fileTypes: string[] | null;
}>;
attachments: string[];
createdAt: string;
updatedAt: string;
};
}
```
## Error Handling
```typescript theme={null}
try {
const response = await axios.get('https://api.langdock.com/assistant/v1/get', ...);
} catch (error) {
if (error.response) {
switch (error.response.status) {
case 400:
console.error('Invalid Assistant ID format');
break;
case 401:
console.error('Invalid or missing API key');
break;
case 403:
console.error('Insufficient permissions - no access to this Assistant');
break;
case 404:
console.error('Assistant not found');
break;
case 500:
console.error('Server error');
break;
}
}
}
```
## Migrating to Agents API
The new Agents API offers improved compatibility with modern AI SDKs. The get endpoint has similar functionality with updated parameter names.
See the equivalent endpoint in the Agents API:
* [Agent Get API](/en/developer/agents-api/agent-get) - Uses `agentId` instead of `assistantId`
Langdock intentionally blocks browser-origin requests to protect your API key and ensure your applications remain secure. For more information, please see our guide on [API Key Best Practices](/en/admin/ai-adoption-and-rollout/best-practices/api-key-best-practices).
