Here is a 1-paragraph summary of the provided text: Mock APIs provide predefined API responses for client applications, allowing developers to design, develop, and ship code efficiently without setting up a backend. Mock APIs can be created locally or externally, with local ones being part of the code repository and maintained by developers, while public mock APIs are accessed over the network and can be automatically generated from an API design specification using tools like OpenAPI Specification. Creating a mock API is straightforward, involving adding a new endpoint, specifying a response, and toggling on mock response, making it easy for teams to get started with API integration and testing.
