How fast does a streaming news API deliver articles? The honest answer is that it depends on several steps, not one number. This guide explains real-time news API latency in plain language, so you know what is slowing your feed down and what you can fix. Every article passes through five stages before it reaches your app: discovery, collection, processing, indexing, and delivery. Each stage adds a small delay, and the slowest one sets your overall speed. The guide shows what happens at each step, where delays usually appear, and why more data enrichment can mean a slightly longer wait. It also covers the biggest factor you can control: polling versus streaming. If your app checks for news every five minutes, you add up to five minutes of delay, even with a fast API. WebSocket streaming pushes matching articles to you as soon as they are ready, which makes it a better fit for alerts, trading dashboards, and live feeds.
