When designing an API that fetches user data based on filters, how would you ensure that the filtering process is efficient and explain the potential time complexities involved?

To ensure efficient filtering in an API, I would use indexed queries if interacting with a database, targeting specific columns for filtering. The time complexity for indexed lookups is generally…

How would you design a REST API endpoint to implement pagination for a large dataset returned from a database, and what considerations should you take into account?

To implement pagination in a REST API, I would typically use query parameters like ‘limit’ and ‘offset’ to control the number of records returned and the starting point. Considerations include…

How would you design an API for an AI agent to manage multi-agent workflows, ensuring scalability and responsiveness to real-time inputs?

The API should adopt a RESTful design that allows agents to register tasks and manage workflows asynchronously. Using WebSockets or Server-Sent Events for real-time communication can enhance responsiveness, while implementing…

How would you design a simple API endpoint to retrieve a list of users from a database based on a given set of filtering criteria?

First, I would define the API endpoint with a clear URL and method, such as GET /users. Then, I would allow query parameters for filtering, such as ?age=30&role=admin, and ensure…

Can you explain what JWT is and how it is used in API authentication?

JWT, or JSON Web Token, is a compact way to securely transmit information between parties as a JSON object. It is commonly used in API authentication to verify the identity…

Can you explain how you would handle versioning an API when making backward-incompatible changes and how you would manage that in Git?

To handle backward-incompatible changes in an API, I would use versioning in the URL, such as /v1/resource and /v2/resource. In Git, I would create a new branch for the new…
