## Install and authenticate

<Tabs>
  <Tab title="Python">
<Steps>
<Step title="Install the SDK">
```bash
pip install mem0ai
```
</Step>
<Step title="Export your API key">
```bash
export MEM0_API_KEY="sk-platform-..."
```
</Step>
<Step title="Create an async client">
```python
import os
from mem0 import AsyncMemoryClient

memory = AsyncMemoryClient(api_key=os.environ["MEM0_API_KEY"])
```
</Step>
</Steps>
  </Tab>
  <Tab title="TypeScript">
<Steps>
<Step title="Install the OSS SDK">
```bash
npm install mem0ai
```
</Step>
<Step title="Load your API key">
```bash
export MEM0_API_KEY="sk-platform-..."
```
</Step>
<Step title="Instantiate the client">
```typescript
import MemoryClient from 'mem0ai';

const memory = new MemoryClient({ apiKey: process.env.MEM0_API_KEY! });
```
</Step>
</Steps>
  </Tab>

## Add memories with metadata

<Tabs>
  <Tab title="Python">
<Steps>
<Step title="Record conversations with metadata">
```python
conversation = [
    {"role": "user", "content": "I'm Morgan, planning a 3-week trip to Japan in May."},
    {"role": "assistant", "content": "Great! I'll track dietary notes and cities you mention."},
    {"role": "user", "content": "Please remember I avoid shellfish and prefer boutique hotels in Tokyo."},
]

result = await memory.add(
    conversation,
    user_id="traveler-42",
    metadata={"trip": "japan-2025", "preferences": ["boutique", "no-shellfish"]},
    run_id="planning-call-1",
)
```
</Step>
</Steps>
  </Tab>
  <Tab title="TypeScript">
<Steps>
<Step title="Capture context-rich memories">
```typescript
const conversation = [
  { role: "user", content: "I'm Morgan, planning a 3-week trip to Japan in May." },
  { role: "assistant", content: "Great! I'll track dietary notes and cities you mention." },
  { role: "user", content: "Please remember I avoid shellfish and love boutique hotels in Tokyo." },
];

const result = await memory.add(conversation, {
  userId: "traveler-42",
  metadata: { trip: "japan-2025", preferences: ["boutique", "no-shellfish"] },
  runId: "planning-call-1",
});
```
</Step>
</Steps>
  </Tab>
</Tabs>

<Info icon="check">
  Successful calls return memories tagged with the metadata you passed. In the dashboard, verify the `trip=japan-2025` tag exists on the new memory.
</Info>

## Retrieve and refine

<Tabs>
  <Tab title="Python">
<Steps>
<Step title="Filter by metadata + reranker">
```python
matches = await memory.search(
    "Any food alerts?",
    filters={"user_id": "traveler-42", "metadata.trip": "japan-2025"},
    rerank=True,
)
```
</Step>
<Step title="Update a memory inline">
```python
await memory.update(
    memory_id=matches["results"][0]["id"],
    text="Morgan avoids shellfish and prefers boutique hotels in central Tokyo.",
)
```
</Step>
</Steps>
  </Tab>
  <Tab title="TypeScript">
<Steps>
<Step title="Search with metadata filters">
```typescript
const matches = await memory.search("Any food alerts?", {
  filters: { user_id: "traveler-42", "metadata.trip": "japan-2025" },
  rerank: true,
});
```
</Step>
<Step title="Apply an update">
```typescript
await memory.update(matches.results[0].id, {
  text: "Morgan avoids shellfish and prefers boutique hotels in central Tokyo.",
});
```
</Step>
</Steps>
  </Tab>
</Tabs>

## Clean up

<Tabs>
  <Tab title="Python">
<Steps>
<Step title="Delete scoped memories">
```python
await memory.delete_all(user_id="traveler-42", run_id="planning-call-1")
```
</Step>
</Steps>
  </Tab>
  <Tab title="TypeScript">
<Steps>
<Step title="Remove the run">
```typescript
await memory.deleteAll({ userId: "traveler-42", runId: "planning-call-1" });
```
</Step>
</Steps>
  </Tab>
</Tabs>

## Quick recovery

- Empty results with filters: log `filters` values and confirm metadata keys match (case-sensitive).

<Warning>
  Metadata keys become part of your filtering schema. Stick to lowercase snake_case (`trip_id`, `preferences`) to avoid collisions down the road.
</Warning>
