Description: A fallback API is used as a backup option when the main API fails. These application programming interfaces are designed to ensure service continuity and minimize downtime in systems that rely on multiple APIs to function properly. Fallback APIs allow developers to implement solutions that can be automatically activated in case the main API is unavailable, whether due to technical issues, maintenance, or traffic overload. Key features of a fallback API include the ability to detect failures in the main API, quick response times, and ease of integration with the existing system. Additionally, they often provide a similar set of functionalities to the main API, allowing for a smooth and uninterrupted transition for end users. In a world where availability and reliability are crucial, fallback APIs have become essential for maintaining the operability of online applications and services, ensuring that users can access the information and functionalities they need without significant interruptions.
