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

## Sign up as an agent

AI agents (Claude Code, Cursor, Codex, …) can mint a working Mem0 API key in under five seconds — no email, no dashboard, no OTP. Four commands end-to-end:

<CodeGroup>
```bash npm
# 1. Install
npm install -g @mem0/cli

# 2. Sign up as an agent (replace `claude-code` with your name)
mem0 init --agent --agent-caller claude-code

# 3. Add a memory
mem0 add "I am using mem0"

# 4. Search
mem0 search "am I using mem0"
```

```bash pip
# 1. Install
pip install mem0-cli

# 2. Sign up as an agent (replace `claude-code` with your name)
mem0 init --agent --agent-caller claude-code

# 3. Add a memory
mem0 add "I am using mem0"

# 4. Search
mem0 search "am I using mem0"
```
</CodeGroup>

The human owner can claim the account later with `mem0 init --email you@yourcompany.com` — same key, memories preserved. See [CLI docs](/platform/cli) for the full reference.

## 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 14+, or cURL

## Installation

<Steps>
<Step title="Install SDK">
<CodeGroup>
```bash pip
pip install mem0ai
```

```bash npm
npm install mem0ai
```

</CodeGroup>
</Step>

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

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

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

```bash cURL
export MEM0_API_KEY="your-api-key"
```

```bash CLI
mem0 init --api-key "your-api-key"
```

</CodeGroup>
</Step>

<Step title="Add a memory">
<CodeGroup>
```python Python
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
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
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
mem0 add "I'm a vegetarian and allergic to nuts." --user-id user123
```

</CodeGroup>
</Step>

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

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

```bash cURL
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
mem0 search "What are my dietary restrictions?" --user-id user123
```

</CodeGroup>

**Output:**

```json
{
  "results": [
    {
      "id": "14e1b28a-2014-40ad-ac42-69c9ef42193d",
      "memory": "Allergic to nuts",
      "user_id": "user123",
      "categories": ["health"],
      "created_at": "2025-10-22T04:40:22.864647-07:00",
      "score": 0.30
    }
  ]
}
```
