The API's focus on decentralized exchange data makes it relevant for projects aiming to interact with or display DeFi market information.

While the API does not require authentication, users should be aware of typical API usage best practices. The straightforward REST interface allows easy integration into various programming environments, although no official SDKs are indicated from the provided information.
