# Quickstart

> Set up your Mem0 Platform account, install the SDK, and store your first memory in under five minutes.

Get started with Mem0 Platform's hosted API in under 5 minutes. This guide shows you how to authenticate and store your first memory.

<Note>
  **Are you an AI agent?** See [Sign up as an agent](/platform/agent-signup) — mint a working API key in four commands, no email or dashboard required.
</Note>

## Prerequisites

* Mem0 Platform account (<a href="https://app.mem0.ai?utm_source=oss&utm_medium=platform-quickstart" rel="nofollow">Sign up here</a>)
* API key (<a href="https://app.mem0.ai/dashboard/settings?tab=api-keys&subtab=configuration" rel="nofollow">Get one from dashboard</a>)
* Python 3.10+, Node.js 18+, or cURL

## Installation

<Steps>
  <Step title="Install SDK">
    <CodeGroup>
      ```bash pip theme={null}
      pip install mem0ai
      ```

      ```bash npm theme={null}
      npm install mem0ai
      ```
    </CodeGroup>
  </Step>

  <Step title="Set your API key">
    <CodeGroup>
      ```python Python theme={null}
      from mem0 import MemoryClient

      client = MemoryClient(api_key="your-api-key")
      ```

      ```javascript JavaScript theme={null}
      import MemoryClient from 'mem0ai';
      const client = new MemoryClient({ apiKey: 'your-api-key' });
      ```

      ```bash cURL theme={null}
      export MEM0_API_KEY="your-api-key"
      ```

      ```bash CLI theme={null}
      mem0 init --api-key "your-api-key"
      ```
    </CodeGroup>
  </Step>

  <Step title="Add a memory">
    <CodeGroup>
      ```python Python theme={null}
      messages = [
          {"role": "user", "content": "I'm a vegetarian and allergic to nuts."},
          {"role": "assistant", "content": "Got it! I'll remember your dietary preferences."}
      ]
      client.add(messages, user_id="user123")
      ```

      ```javascript JavaScript theme={null}
      const messages = [
          {"role": "user", "content": "I'm a vegetarian and allergic to nuts."},
          {"role": "assistant", "content": "Got it! I'll remember your dietary preferences."}
      ];
      await client.add(messages, { userId: "user123" });
      ```

      ```bash cURL theme={null}
      curl -X POST https://api.mem0.ai/v3/memories/add/ \
        -H "Authorization: Token $MEM0_API_KEY" \
        -H "Content-Type: application/json" \
        -d '{
          "messages": [
            {"role": "user", "content": "Im a vegetarian and allergic to nuts."},
            {"role": "assistant", "content": "Got it! Ill remember your dietary preferences."}
          ],
          "user_id": "user123"
        }'
      ```

      ```bash CLI theme={null}
      mem0 add "I'm a vegetarian and allergic to nuts." --user-id user123
      ```
    </CodeGroup>
  </Step>

  <Step title="Search memories">
    <CodeGroup>
      ```python Python theme={null}
      results = client.search("What are my dietary restrictions?", filters={"user_id": "user123"})
      print(results)
      ```

      ```javascript JavaScript theme={null}
      const results = await client.search("What are my dietary restrictions?", { filters: { user_id: "user123" } });
      console.log(results);
      ```

      ```bash cURL theme={null}
      curl -X POST https://api.mem0.ai/v3/memories/search/ \
        -H "Authorization: Token $MEM0_API_KEY" \
        -H "Content-Type: application/json" \
        -d '{
          "query": "What are my dietary restrictions?",
          "filters": {"user_id": "user123"}
        }'
      ```

      ```bash CLI theme={null}
      mem0 search "What are my dietary restrictions?" --user-id user123
      ```
    </CodeGroup>

    **Output:**

    ```json theme={null}
    {
      "results": [
        {
          "id": "14e1b28a-2014-40ad-ac42-69c9ef42193d",
          "memory": "Allergic to nuts",
