The Realtime API allows you to ingest updates across supported Wikimedia projects as they happen, in the form of real-time stream or batch files (updated hourly). Wikimedia projects are written by volunteers who are continually updating and improving at all hours of the day. If you are building a product that is in tune with current events or at risk for potential vandalism, we recommend subscribing to the Realtime API to ensure you are receiving the updates from the Wikimedia volunteer community to improve the up-to-dateness and stability of the dataset.
