Our unauthenticated and free endpoints are supported by a wide range of popular SDK and libraries including GDK, LWK and BDK. However, our Enterprise endpoints require an additional authentication step before users can make an API request to the desired endpoints (e.g. get hash of last block, estimate fees, etc.)
Currently, Enterprise customers have to include this authentication step in their applications that, while standard, still requires some small changes on the client side.
- See How to make a REST API request with your API keys to learn more.
At this moment this OAuth2 authentication protocol is included in LWK and we are working on adding built-in authentication within other popular libraries like BDK so users can have a plug-and-play solution.
