API throttling is a technique that limits the number of requests a user can make to an API within a specific time frame. It's used to prevent a single user from consuming too many resources and to ensure that the API remains available to all users.

Here are some benefits of API throttling:

Manages server resources: Throttling helps manage server resources by preventing overuse.

Prevents abuse: Throttling can help prevent abuse of the API.

Ensures fair usage: Throttling can help ensure fair usage among all API consumers.

When a client exceeds the API's throttling limits, the API may respond with an error, delay the request, or queue it for later processing.

Organizations use API throttling for a variety of goals, including:
security, scalability, performance, monetization, authentication, and availability.
