Real-time Data

Definition updated April 2026

What is real-time data?

Real-time data is information delivered with minimal delay between when an event occurs and when it becomes available to your application. APIs serving real-time data reflect the current state of the source system at the moment the request is made, not a cached or pre-processed snapshot.

Examples include current hotel room pricing, active property listings with up-to-the-hour status, live product prices and stock levels, and today's financial market quotes. Real-time data enables decisions based on the current state of the world, not yesterday's.

Real-time data delivery requires low-latency infrastructure and fresh data pipelines. For price comparison engines or property search portals, real-time APIs are non-negotiable - showing a stale price can mislead users and damage trust.
