Welcome to the Cronoscan APIs documentation 🚀.

As a means to provide equitable access to blockchain data, we've developed the Cronoscan Developer APIs to empower developers with direct access to Cronoscan's block explorer data and services via GET/POST requests.

Cronoscan's APIs are provided as a community service and without warranty, so please use what you need and no more.

Source attribution via a backlink or a mention that your app is "Powered by Cronoscan APIs" is required except for personal/private usage.

API Endpoints

For that you may find a suitable endpoint from our wide range of APIs that you can simply query to provide data while you remain fully focused on building your applications.


There is an overwhelming amount of data 📈 that can be extracted from the Cronos Chain.

We've helped you take the first steps by writing some thorough tutorials on how to query and derive popular blockchain metrics.

For power users, we've also added guides such as how you can programmatically verify contracts through API calls and more advanced use cases of endpoints.
