</Note>

## 1. Installation

<CodeGroup>
```bash pip
pip install mem0ai
```

```bash npm
npm install mem0ai
```

</CodeGroup>

## 2. API Key Setup

1. Sign in to [Mem0 Platform](https://mem0.dev/pd-api)
2. Copy your API Key from the dashboard

![Get API Key from Mem0 Platform](/images/platform/api-key.png)

## 3. Instantiate Client

<CodeGroup>
```python Python
import os
from mem0 import MemoryClient

os.environ["MEM0_API_KEY"] = "your-api-key"

client = MemoryClient()
```

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

</CodeGroup>

### 3.1 Instantiate Async Client (Python only)

For asynchronous operations in Python, you can use the AsyncMemoryClient:

```python Python
import os
from mem0 import AsyncMemoryClient

os.environ["MEM0_API_KEY"] = "your-api-key"

client = AsyncMemoryClient()


async def main():
    messages = [
        {"role": "user", "content": "I'm travelling to SF"}
    ]
    response = await client.add(messages, user_id="john")
    print(response)

await main()
```

## 4. Memory Operations

Mem0 provides a simple and customizable interface for performing CRUD operations on memory.

### 4.1 Create Memories

#### Long-term memory for a user

These memory instances persist across multiple sessions. Ideal for maintaining memory over long time spans.

<CodeGroup>

```python Python
messages = [
    {"role": "user", "content": "Hi, I'm Alex. I'm a vegetarian and I'm allergic to nuts."},
    {"role": "assistant", "content": "Hello Alex! I've noted that you're a vegetarian and have a nut allergy. I'll keep this in mind for any food-related recommendations or discussions."}
]

client.add(messages, user_id="alex", metadata={"food": "vegan"})
```

```javascript JavaScript
const messages = [
    {"role": "user", "content": "Hi, I'm Alex. I'm a vegetarian and I'm allergic to nuts."},
    {"role": "assistant", "content": "Hello Alex! I've noted that you're a vegetarian and have a nut allergy. I'll keep this in mind for any food-related recommendations or discussions."}
];
client.add(messages, { user_id: "alex", metadata: { food: "vegan" } })
    .then(response => console.log(response))
    .catch(error => console.error(error));
```

```bash cURL
curl -X POST "https://api.mem0.ai/v1/memories/" \
     -H "Authorization: Token your-api-key" \
     -H "Content-Type: application/json" \
     -d '{
         "messages": [
             {"role": "user", "content": "Hi, I'm Alex. I'm a vegetarian and I'm allergic to nuts."},
             {"role": "assistant", "content": "Hello Alex! I've noted that you're a vegetarian and have a nut allergy. I'll keep this in mind for any food-related recommendations or discussions."}
         ],
         "user_id": "alex",
         "metadata": {
             "food": "vegan"
         }
     }'
```

```json Output
{
    "results": [
        {
            "memory": "Name is Alex",
            "event": "ADD"
        },
        {
            "memory": "Is a vegetarian",
            "event": "ADD"
        },
        {
            "memory": "Is allergic to nuts",
            "event": "ADD"
        }
    ]
}
```

</CodeGroup>

<Note>
    When passing `user_id`, memories are primarily created based on user messages, but may be influenced by assistant messages for contextual understanding. For example, in a conversation about food preferences, both the user's stated preferences and their responses to the assistant's questions would form user memories. Similarly, when using `agent_id`, assistant messages are prioritized, but user messages might influence the agent's memories based on context. This approach ensures comprehensive memory creation while maintaining appropriate attribution to either users or agents.
    
    **Example:**
    ```
    User: My favorite cuisine is Italian
    Assistant: Nice! What about Indian cuisine?
    User: Don't like it much since I cannot eat spicy food
    
    Resulting user memories:
    memory1 - Likes Italian food
    memory2 - Doesn't like Indian food since cannot eat spicy 
    
    (memory2 comes from user's response about Indian cuisine)
    ```
</Note>

<Note>Metadata allows you to store structured information (location, timestamp, user state) with memories. Add it during creation to enable precise filtering and retrieval during searches.</Note>


#### Short-term memory for a user session

These memory instances persist only for the duration of a user session. Ideal for non-repetitive interactions and managing context windows efficiently.

<CodeGroup>

```python Python
messages = [
    {"role": "user", "content": "I'm planning a trip to Japan next month."},
    {"role": "assistant", "content": "That's exciting, Alex! A trip to Japan next month sounds wonderful. Would you like some recommendations for vegetarian-friendly restaurants in Japan?"},
    {"role": "user", "content": "Yes, please! Especially in Tokyo."},
    {"role": "assistant", "content": "Great! I'll remember that you're interested in vegetarian restaurants in Tokyo for your upcoming trip. I'll prepare a list for you in our next interaction."}
]

client.add(messages, user_id="alex", run_id="trip-planning-2024")
```

```javascript JavaScript
const messages = [
    {"role": "user", "content": "I'm planning a trip to Japan next month."},
    {"role": "assistant", "content": "That's exciting, Alex! A trip to Japan next month sounds wonderful. Would you like some recommendations for vegetarian-friendly restaurants in Japan?"},
    {"role": "user", "content": "Yes, please! Especially in Tokyo."},
    {"role": "assistant", "content": "Great! I'll remember that you're interested in vegetarian restaurants in Tokyo for your upcoming trip. I'll prepare a list for you in our next interaction."}
];
client.add(messages, { user_id: "alex", run_id: "trip-planning-2024" })
    .then(response => console.log(response))
    .catch(error => console.error(error));
```

```bash cURL
curl -X POST "https://api.mem0.ai/v1/memories/" \
     -H "Authorization: Token your-api-key" \
     -H "Content-Type: application/json" \
     -d '{
         "messages": [
             {"role": "user", "content": "I'm planning a trip to Japan next month."},
             {"role": "assistant", "content": "That's exciting, Alex! A trip to Japan next month sounds wonderful. Would you like some recommendations for vegetarian-friendly restaurants in Japan?"},
             {"role": "user", "content": "Yes, please! Especially in Tokyo."},
             {"role": "assistant", "content": "Great! I'll remember that you're interested in vegetarian restaurants in Tokyo for your upcoming trip. I'll prepare a list for you in our next interaction."}
         ],
         "user_id": "alex",
         "run_id": "trip-planning-2024"
     }'
```

```json Output
{
  "results": [
    {
      "memory": "Planning a trip to Japan next month",
      "event": "ADD"
    },
    {
      "memory": "Interested in vegetarian restaurants in Tokyo",
      "event": "ADD"
    }
  ]
}
```

</CodeGroup>

#### Long-term memory for agents
Add a memory layer for the assistants and agents so that their responses remain consistent across sessions. 

<CodeGroup>

```python Python
messages = [
    {"role": "system", "content": "You are an AI tutor with a personality. Give yourself a name for the user."},
    {"role": "assistant", "content": "Understood. I'm an AI tutor with a personality. My name is Alice."}
]

client.add(messages, agent_id="ai-tutor")
```

```javascript JavaScript
const messages = [
    {"role": "system", "content": "You are an AI tutor with a personality. Give yourself a name for the user."},
    {"role": "assistant", "content": "Understood. I'm an AI tutor with a personality. My name is Alice."}
];
client.add(messages, { agent_id: "ai-tutor" })
    .then(response => console.log(response))
    .catch(error => console.error(error));
```

```bash cURL
curl -X POST "https://api.mem0.ai/v1/memories/" \
     -H "Authorization: Token your-api-key" \
     -H "Content-Type: application/json" \
     -d '{
         "messages": [
             {"role": "system", "content": "You are an AI tutor with a personality. Give yourself a name for the user."},
             {"role": "assistant", "content": "Understood. I'm an AI tutor with a personality. My name is Alice."}
         ],
         "agent_id": "ai-tutor"
     }'
```

```json Output
{
    "results": [
        {
            "memory": "Name is Alex",
            "event": "ADD"
        },
        {
            "memory": "Is a vegetarian",
            "event": "ADD"
        },
        {
            "memory": "Is allergic to nuts",
            "event": "ADD"
        }
    ]
}
```
</CodeGroup>

<Note>
    The `agent_id` retains memories exclusively based on messages generated by the assistant or those explicitly provided as input to the assistant. Messages outside these criteria are not stored as memory.
</Note>

#### Long-term memory for both users and agents
When you provide both `user_id` and `agent_id`, Mem0 will store memories for both identifiers separately:
- Memories from messages with `"role": "user"` are automatically tagged with the provided `user_id`
- Memories from messages with `"role": "assistant"` are automatically tagged with the provided `agent_id`
- During retrieval, you can provide either `user_id` or `agent_id` to access the respective memories
- You can continuously enrich existing memory collections by adding new memories to the same `user_id` or `agent_id` in subsequent API calls, either together or separately, allowing for progressive memory building over time
- This dual-tagging approach enables personalized experiences for both users and AI agents in your application

<CodeGroup>

```python Python
messages = [
    {"role": "user", "content": "I'm travelling to San Francisco"},
    {"role": "assistant", "content": "That's great! I'm going to Dubai next month."},
]

client.add(messages=messages, user_id="user1", agent_id="agent1")
```

```javascript JavaScript
const messages = [
    {"role": "user", "content": "I'm travelling to San Francisco"},
    {"role": "assistant", "content": "That's great! I'm going to Dubai next month."},
]

client.add(messages, { user_id: "user1", agent_id: "agent1" })
    .then(response => console.log(response))
    .catch(error => console.error(error));
```

```bash cURL
curl -X POST "https://api.mem0.ai/v1/memories/" \
     -H "Authorization: Token your-api-key" \
     -H "Content-Type: application/json" \
     -d '{
         "messages": [
             {"role": "user", "content": "I'm travelling to San Francisco"},
             {"role": "assistant", "content": "That's great! I'm going to Dubai next month."},
         ],
         "user_id": "user1",
         "agent_id": "agent1"
     }'
```

```json Output
{
    "results": [
        {
            // memory from user1
            "id": "c57abfa2-f0ac-48af-896a-21728dbcecee0",
            "data": {"memory": "Travelling to San Francisco"},
            "event": "ADD"
        },
        {
            // memory from agent1
            "id": "0e8c003f-7db7-426a-9fdc-a46f9331a0c2",
            "data": {"memory": "Going to Dubai next month"},
            "event": "ADD"
        }
    ]
}
```

</CodeGroup>


#### Async Memory Addition

When you set `async_mode=True`, memory processing happens completely asynchronously in the background. This allows for faster API responses while your memories are processed. The memories will be available on the dashboard and for retrieval within a few seconds.

<CodeGroup>

```python Python
messages = [
    {"role": "user", "content": "I love hiking and outdoor activities"},
    {"role": "assistant", "content": "That's great! I'll remember your interest in hiking and outdoor activities for future recommendations."}
]

client.add(messages, user_id="alex", async_mode=True)
```

```javascript JavaScript
const messages = [
    {"role": "user", "content": "I love hiking and outdoor activities"},
    {"role": "assistant", "content": "That's great! I'll remember your interest in hiking and outdoor activities for future recommendations."}
];

client.add(messages, { user_id: "alex", async_mode: true })
    .then(response => console.log(response))
    .catch(error => console.error(error));
```

```bash cURL
curl -X POST "https://api.mem0.ai/v1/memories/" \
     -H "Authorization: Token your-api-key" \
     -H "Content-Type: application/json" \
     -d '{
         "messages": [
             {"role": "user", "content": "I love hiking and outdoor activities"},
             {"role": "assistant", "content": "That's great! I'll remember your interest in hiking and outdoor activities for future recommendations."}
         ],
         "user_id": "alex",
         "async_mode": true
     }'
```

```json Output
{
    "results": [
        {
            "message": "Memory processing has been queued for background execution"
        }
    ]
}
```

</CodeGroup>

#### Monitor Memories

You can monitor memory operations on the platform dashboard:

![Mem0 Platform Activity](/images/platform/activity.png)

### 4.2 Search Memories

#### General Memory Search

Pass user messages, interactions, and queries into our search method to retrieve relevant memories.

<Note> The `search` method supports two output formats: `v1.0` (default) and `v1.1`. To use the latest format, which provides more detailed information about each memory operation, set the `output_format` parameter to `v1.1`: </Note>

<CodeGroup>

```python Python
query = "What should I cook for dinner today?"

client.search(query, user_id="alex")
```

```javascript JavaScript
const query = "What should I cook for dinner today?";
client.search(query, { user_id: "alex", output_format: "v1.1" })
    .then(results => console.log(results))
    .catch(error => console.error(error));
```

```bash cURL
curl -X POST "https://api.mem0.ai/v1/memories/search/" \
     -H "Authorization: Token your-api-key" \
     -H "Content-Type: application/json" \
     -d '{
         "query": "What should I cook for dinner today?",
         "user_id": "alex",
         "output_format": "v1.1"
     }'
```

```json Output
{
    "results": [
        {
            "id": "7f165f7e-b411-4afe-b7e5-35789b72c4a5",
            "memory": "Vegetarian. Allergic to nuts.",
            "user_id": "alex",
            "metadata": {"food": "vegan"},
            "categories": ["food_preferences"],
            "immutable": false,
            "expiration_date": null,
            "created_at": "2024-07-20T01:30:36.275141-07:00",
            "updated_at": "2024-07-20T01:30:36.275172-07:00"
        }
    ]
}
```
</CodeGroup>

Use category and metadata filters:

<CodeGroup>

```python Python
query = "What do you know about me?"

client.search(query, categories=["food_preferences"], metadata={"food": "vegan"})
```

```javascript JavaScript
const query = "What do you know about me?";
client.search(query, categories=["food_preferences"], metadata={"food": "vegan"})
    .then(results => console.log(results))
    .catch(error => console.error(error));
```

```bash cURL
curl -X POST "https://api.mem0.ai/v1/memories/search/?version=v2" \
     -H "Authorization: Token your-api-key" \
     -H "Content-Type: application/json" \
     -d '{
         "query": "What do you know about me?",
         "categories": ["food_preferences"],
         "metadata": {"food": "vegan"}
     }'
```

```json Output
{
    "results": [
        {
            "id": "7f165f7e-b411-4afe-b7e5-35789b72c4a5",
            "memory": "Name: Alex. Vegetarian. Allergic to nuts.",
            "user_id": "alex",
            "metadata": {"food": "vegan"},
            "categories": ["food_preferences"],
            "immutable": false,
            "expiration_date": null,
            "created_at": "2024-07-20T01:30:36.275141-07:00",
            "updated_at": "2024-07-20T01:30:36.275172-07:00"
        }
    ]
}
```
</CodeGroup>


#### Search using custom filters

Our advanced search allows you to set custom search filters. You can filter by user_id, agent_id, app_id, run_id, created_at, updated_at, categories, and text. The filters support logical operators (AND, OR) and comparison operators (in, gte, lte, gt, lt, ne, contains, icontains, *). The wildcard character (*) matches everything for a specific field. For more details, see [V2 Search Memories](/api-reference/memory/v2-search-memories).

Here you need to define `version` as `v2` in the search method.

Example 1: Search using user_id and agent_id filters

<CodeGroup>

```python Python
query = "What do you know about me?"
filters = {
   "OR":[
      {
         "user_id":"alex"
      },
      {
         "agent_id":{
            "in":[
               "travel-assistant",
               "customer-support"
            ]
         }
      }
   ]
}
client.search(query, version="v2", filters=filters)
```

```javascript JavaScript
const query = "What do you know about me?";
const filters = {
   "OR":[
      {
         "user_id":"alex"
      },
      {
         "agent_id":{
            "in":[
               "travel-assistant",
               "customer-support"
            ]
         }
      }
   ]
};
client.search(query, { version: "v2", filters })
    .then(results => console.log(results))
    .catch(error => console.error(error));
```

```bash cURL
curl -X POST "https://api.mem0.ai/v1/memories/search/?version=v2" \
     -H "Authorization : Token your - api - key" \

Example 2: Search using date filters
<CodeGroup>
```python Python
query = "What do you know about me?"
filters = {
    "AND": [
        {"created_at": {"gte": "2024-07-20", "lte": "2024-07-10"}},
        {"user_id": "alex"}
    ]

### 4.4 Get All Memories

Fetch all memories for a user, agent, or run using the getAll() method.

<Note> The `get_all` method supports two output formats: `v1.0` (default) and `v1.1`. To use the latest format, which provides more detailed information about each memory operation, set the `output_format` parameter to `v1.1`: </Note>
<Note> We're soon deprecating the default output format for get_all() method, which returned a list. Once the changes are live, paginated response will be the only supported format, with 100 memories per page by default. You can customize this using the `page` and `page_size` parameters. </Note>

The following examples showcase the paginated output format. 

#### Get all memories of a user

```python Python
memories = client.get_all(user_id="alex", page=1, page_size=50)

#### Get all memories by categories

You can filter memories by their categories when using get_all:

<CodeGroup>

```python Python
# Get memories with specific categories
memories = client.get_all(user_id="alex", categories=["likes"])

# Get memories with multiple categories
memories = client.get_all(user_id="alex", categories=["likes", "food_preferences"])

# Custom pagination with categories
memories = client.get_all(user_id="alex", categories=["likes"], page=1, page_size=50)

# Get memories with specific keywords
memories = client.get_all(user_id="alex", keywords="to play", page=1, page_size=50)
```

```javascript JavaScript
// Get memories with specific categories
client.getAll({ user_id: "alex", categories: ["likes"] })
    .then(memories => console.log(memories))
    .catch(error => console.error(error));

// Get memories with multiple categories
client.getAll({ user_id: "alex", categories: ["likes", "food_preferences"] })
    .then(memories => console.log(memories))
    .catch(error => console.error(error));

// Custom pagination with categories
client.getAll({ user_id: "alex", categories: ["likes"], page: 1, page_size: 50 })
    .then(memories => console.log(memories))
    .catch(error => console.error(error));

// Get memories with specific keywords
client.getAll({ user_id: "alex", keywords: "to play", page: 1, page_size: 50 })
    .then(memories => console.log(memories))
    .catch(error => console.error(error));
```

#### Get all memories using custom filters

Our advanced retrieval allows you to set custom filters when fetching memories. You can filter by user_id, agent_id, app_id, run_id, created_at, updated_at, categories, and keywords. The filters support logical operators (AND, OR) and comparison operators (in, gte, lte, gt, lt, ne, contains, icontains, *). The wildcard character (*) matches everything for a specific field. For more details, see [v2 Get Memories](/api-reference/memory/v2-get-memories).

Here you need to define `version` as `v2` in the get_all method.

Example 1. Get all memories using user_id and date filters

<CodeGroup>

```python Python
filters = {
   "AND":[
      {
         "user_id":"alex"
      },
      {
         "created_at":{
            "gte":"2024-07-01",
            "lte":"2024-07-31"
         }
      },
      {
         "categories":{
            "contains": "food_preferences"
         }
      }
   ]
}

# Default (No Pagination)
client.get_all(version="v2", filters=filters)

# Pagination (You can also use the page and page_size parameters)
client.get_all(version="v2", filters=filters, page=1, page_size=50)
```

```javascript JavaScript
const filters = {
   "AND":[
      {
         "user_id":"alex"
      },
      {
         "created_at":{
            "gte":"2024-07-01",
            "lte":"2024-07-31"
         }
      },
      {
         "categories":{
            "contains": "food_preferences"
         }
      }
   ]
};

// Default (No Pagination)
client.getAll({ version: "v2", filters })
    .then(memories => console.log(memories))
    .catch(error => console.error(error));

// Pagination (You can also use the page and page_size parameters)
client.getAll({ version: "v2", filters, page: 1, page_size: 50 })
    .then(memories => console.log(memories))
    .catch(error => console.error(error));

### 4.5 Memory History

Get history of how a memory has changed over time.

<CodeGroup>

```python Python
# Add some message to create history
messages = [{"role": "user", "content": "I recently tried chicken and I loved it. I'm thinking of trying more non-vegetarian dishes.."}]
client.add(messages, user_id="alex")

# Add second message to update history
messages.append({'role': 'user', 'content': 'I turned vegetarian now.'})
client.add(messages, user_id="alex")

# Get history of how memory changed over time
memory_id = "<memory-id-here>"
history = client.history(memory_id)
```

```javascript JavaScript
// Add some message to create history
let messages = [{ role: "user", content: "I recently tried chicken and I loved it. I'm thinking of trying more non-vegetarian dishes.." }];
client.add(messages, { user_id: "alex" })

        messages.push({ role: 'user', content: 'I turned vegetarian now.' });
        return client.add(messages, { user_id: "alex" });
    })
    .then(result => {
        // Get history of how memory changed over time
        const memoryId = result.id; // Assuming the API returns the memory ID
        return client.history(memoryId);
    })
    .then(history => console.log(history))
    .catch(error => console.error(error));
```

messages = [
    {"role": "user", "content": "Delete all of my food preferences"}
]
client.add(messages, user_id="alex")
```

```javascript JavaScript

    {"role": "user", "content": "Delete all of my food preferences"}
]
client.add(messages, { user_id: "alex" })
    .then(result => console.log(result))
    .catch(error => console.error(error));

### 4.11 Working with Mem0 in TypeScript
Manage memories using TypeScript with Mem0. Mem0 has completet TypeScript support Below is an example demonstrating how to add and search memories.

<CodeGroup>
```typescript TypeScript
import MemoryClient, { Message, SearchOptions, MemoryOptions }  from 'mem0ai';

const apiKey = 'your-api-key-here';
const client = new MemoryClient(apiKey);

// Messages
const messages: Message[] = [
    { role: "user", content: "Hi, I'm Alex. I'm a vegetarian and I'm allergic to nuts." },
    { role: "assistant", content: "Hello Alex! I've noted that you're a vegetarian and have a nut allergy. I'll keep this in mind for any food-related recommendations or discussions." }
];

// ADD
const memoryOptions: MemoryOptions = {
    user_id: "alex",
    agent_id: "travel-assistant"
}

client.add(messages, memoryOptions)
  .then(result => console.log(result))
  .catch(error => console.error(error));

// SEARCH
const query: string = "What do you know about me?";
const searchOptions: SearchOptions = {
    user_id: "alex",
    filters: {
        OR: [
          { agent_id: "travel-assistant" },
          { user_id: "alex" }
        ]
      },
      threshold: 0.1,
      api_version: 'v2'
}
  
client.search(query, searchOptions)
.then(results => console.log(results))
.catch(error => console.error(error));
