Blockscout API Usage

Our Universal Blockscout API is now available, and per-instance API support has been deprecated. Please go to https://dev.blockscout.com/ to get an API key and start exploring.

Note: Your old MyAccount API keys and prior routes will not work with the new Blockscout API. Get a new key and update your routes.
Blockscout v12.0.0 was released on 7 October, 2026 and is rolling out to hosted instances in a gradual fashion. It includes breaking changes for API integrators. Please see the v12.0.0 release page for details.
