# Filtered Stream

> Receive near real-time Posts that match custom rules with X API v2 Filtered Stream, using powerful operators to filter the public Post firehose.

export const Button = ({href, children}) => {
  return <div className="not-prose group">
    <a href={href}>
      <button className="flex items-center space-x-2.5 py-1 px-4 bg-primary-dark dark:bg-white text-white dark:text-gray-950 rounded-full group-hover:opacity-[0.9] font-medium">
        <span>
          {children}
        </span>
        <svg width="3" height="24" viewBox="0 -9 3 24" class="h-6 rotate-0 overflow-visible"><path d="M0 0L3 3L0 6" fill="none" stroke="currentColor" stroke-width="1.5" stroke-linecap="round"></path></svg>
      </button>
    </a>
  </div>;
};

The Filtered Stream endpoints let you receive near real-time Posts that match your filter rules. Create rules using powerful operators, then connect to a persistent stream to receive matching Posts as they're published.

<Note>
  Filtered Stream prioritizes data hydration and delivery, with approximately 6-7 seconds of P99 latency. For lower latency requirements, see [Powerstream](/x-api/powerstream/introduction).

## How it works

1. **Create rules** — Define filter rules using operators
2. **Connect to stream** — Establish a persistent HTTP connection
3. **Receive Posts** — Get matching Posts in near real-time

| POST   | [`/2/tweets/search/stream/rules`](/x-api/stream/update-stream-rules) | Add or delete rules   |
| GET    | [`/2/tweets/search/stream/rules`](/x-api/stream/get-stream-rules)    | List current rules    |

<Note>
  Some operators require specific tiers. The `embedding:` semantic operator is available **only for Filtered Stream** on Enterprise plans with Embedding tier access. Standard Pay-per-use access includes core operators only.
</Note>

## Building rules

Rules use the same operators as search queries:

```
(AI OR "machine learning") lang:en -is:retweet
```

### Example rules

| Rule                                | Matches                                                               |
| :---------------------------------- | :-------------------------------------------------------------------- |
| `#python`                           | Posts with #python hashtag                                            |
| `from:elonmusk`                     | Posts by @elonmusk                                                    |
| `"breaking news" has:images`        | Posts with phrase and images                                          |
| `(@XDevelopers OR @X) -is:retweet`  | Mentions, excluding retweets                                          |
| `embedding:"climate change policy"` | Posts semantically about climate policy (Enterprise + Embedding tier) |

## Connecting to the stream

Establish a persistent HTTP connection to receive Posts:

```python theme={null}
import requests

def stream_posts(bearer_token):
    url = "https://api.x.com/2/tweets/search/stream"
    headers = {"Authorization": f"Bearer {bearer_token}"}
    
    response = requests.get(url, headers=headers, stream=True)
    
    for line in response.iter_lines():
        if line:
            print(line.decode("utf-8"))
```

### Keep-alive signals

The stream sends blank lines (`\r\n`) every 20 seconds to maintain the connection. If you don't receive data or a keep-alive for 20 seconds, reconnect.

  </Card>

  </Card>
</CardGroup>

## Webhook delivery

Instead of maintaining a persistent connection, you can receive Posts via webhooks:

  Set up webhook delivery for filtered stream
</Card>

***

## Post edits

The stream delivers edited Posts with their edit history. Each edit creates a new Post ID:

```json theme={null}
{
  "data": {
    "id": "1234567893",
    "text": "Hello world! (edited)",
    "edit_history_tweet_ids": ["1234567890", "1234567891", "1234567893"]
  }
}
```
