The X API alternative built for real-time trading

TweetStream offers a WebSocket API that streams tweets in real time for monitored accounts. Each alert includes enriched metadata like token detection and OCR so you can act on signals faster than raw tweet polling.

TweetStream provides a WebSocket endpoint at wss://ws.tweetstream.io/ws with subprotocol authentication. It is built for real-time streaming without polling and supports structured JSON payloads for trading systems.

TweetStream keeps one authenticated WebSocket open and pushes events from the X/Twitter accounts you configure. It is built for account-specific trading feeds, not whole-network keyword search or broad social listening.

It can be when your team would otherwise pay for Post reads and maintain stream handling, recovery, OCR, token detection, price lookups, and alert routing. TweetStream starts at $199/month for 50 monitored accounts. Compare that flat plan with your expected X reads and engineering cost; it is not cheaper for every X API use case.

X publishes the current pay-per-use rate card at docs.x.com/x-api/getting-started/pricing. It currently lists Posts: Read at $0.005 per returned resource, 24-hour UTC deduplication as a soft guarantee, and a 2M Post-read cap per monthly billing cycle. Confirm the rate in Developer Console before purchase because X says prices can change.

Use a WebSocket connection with your API key and subscribe to TweetStream's real-time feed. The service pushes alerts immediately when tracked accounts post, so you can process updates in your application without polling.
