Introduction

Powerstream is our lowest-latency streaming API for accessing public X data in real-time. Reference for the Enterprise X API tier covering powerstream.

Powerstream is our lowest-latency streaming API for accessing public X data in real-time. Unlike other streaming endpoints that prioritize data hydration and delivery (with ~6-7 seconds P99 latency), Powerstream is optimized for speed and delivers data with minimal delay.

Similar to the legacy GNIP Powertrack API, it uses rules to filter Posts based on keywords, operators, and metadata. Once a persistent HTTP connection is made to the Powerstream endpoint, you can start receiving matching Posts in real-time.

Currently, Powerstream supports up to 1,000 rules and each rule can be 2048 characters.

Key features

• Real-time data delivery: Lowest latency option for streaming Posts as they’re published.
• Precise filtering: Filter for exactly the data you are looking for using Boolean queries with operators.
• Delivery: JSON response over HTTP/1.1 chunked transfer encoding.
• Local datacenter support: Fetch Posts only from the local datacenter to further reduce latency by avoiding replication lag.

The Powerstream API is a premium offering available under select Enterprise plans.
