API Contracts are agreements between API developers and API consumers. In this video, we explain what that means, and why API Contracts are an important part of building good APIs.

Let me summarize the API contract. It defines the relationship between API developers and API users. While it often exists as a conceptual agreement, it's best documented in writing. Tools like Swagger or OpenAPI can facilitate this. The API contract regulates how clients make and send requests, and how the API responds. The written format is typically in JSON.
