The X API supports real-time data via endpoints like the Filtered Stream Endpoint, delivering matching Posts as they occur. This requires making a persistent http connection.

​
Setup and Basic Streaming

​
Synchronous

from xdk import Client

# Initialize client
client = Client(bearer_token="your_bearer_token")

# Stream posts (make sure you have rules set up first)
for post_response in client.stream.posts():
    data = post_response.model_dump()
    
    if 'data' in data and data['data']:
        tweet = data['data']
        print(f"Post: {tweet.get('text', '')}")

​
Async

import asyncio
from asyncio import Queue
import threading
from xdk import Client

async def stream_posts_async(client: Client):
    queue = Queue()
    loop = asyncio.get_event_loop()
    stop = threading.Event()
    
    def run_stream():
        for post in client.stream.posts():
            if stop.is_set():
                break
            asyncio.run_coroutine_threadsafe(queue.put(post), loop)
        asyncio.run_coroutine_threadsafe(queue.put(None), loop)
    
    threading.Thread(target=run_stream, daemon=True).start()
    
    while True:
        post = await queue.get()
        if post is None:
            break
        data = post.model_dump()
        if 'data' in data and data['data']:
            print(f"Post: {data['data'].get('text', '')}")
    stop.set()

async def main():
    client = Client(bearer_token="your_bearer_token")
    await stream_posts_async(client)

asyncio.run(main())

Rule Management

Rules define filters on what specific data you are looking for(e.g. keywords, users etc). You can learn more about how to build rules using this guide Adding Rules: 
from xdk.stream.models import UpdateRulesRequest

# Add a rule
add_rules = {
    "add": [
        {"value": "from:xdevelopers", "tag": "official_updates"}
    ]
}

request_body = UpdateRulesRequest(**add_rules)
response = client.stream.update_rules(body=request_body)
Deleting Rules: 
from xdk.stream.models import UpdateRulesRequest

delete_rules = {
    "delete": {
        "ids": ["rule_id_1", "rule_id_2"]
    }
}

request_body = UpdateRulesRequest(**delete_rules)
response = client.stream.update_rules(body=request_body)
Listing Rules: 
response = client.stream.get_rules()

# Print rules
for rule in response.data:
    print(f"ID: {rule.id}, Value: {rule.value}, Tag: {rule.tag}")
For full rule syntax, see X Streaming Rules Docs.

Troubleshooting

  • 403 Forbidden: Invalid auth or insufficient permissions.
  • 420 Enhance Your Calm: Rate limited; wait and retry.
  • No Data: Check rules with get_rules(); ensure matching Posts exist.
