Twitter API for Real-time Tweet Retrieval

For retrieving tweets from specific accounts in real-time with very low latency (under 1-2 seconds), you have a few options with the Twitter API Pro plan:

Filtered Stream API

The Filtered Stream endpoint is your best option for real-time monitoring with low latency:

GET /2/tweets/search/stream

With the Pro plan, you can:

• Set up rules to track specific accounts
• Receive tweets as they happen with minimal delay (typically milliseconds to 1 second)
• Connect via a persistent HTTP connection that pushes new tweets to you

Example rule to track Elon Musk's tweets:

from:elonmusk

Implementation Approach

1. Set up your stream rules:

JAVASCRIPTCopied
// Set rules for the accounts you want to monitor
const rules = [
  { value: 'from:elonmusk' },
  { value: 'from:other_account' }
];

// API call to set up these rules
await setFilterRules(rules);

2. Connect to the stream:

JAVASCRIPTCopied
// Connect to the filtered stream endpoint
const stream = await connectToFilteredStream();

// Process tweets as they arrive in real-time
stream.on('data', (tweet) => {
  // Process tweet here - latency will be minimal
  console.log('New tweet received:', tweet);
});

The Pro plan ($5k/month) is appropriate for this use case as it provides the necessary rate limits and access to the streaming endpoints required for real-time monitoring with the latency requirements you specified.
