Can the same API keys be used across different explorers?

Every block explorer built by Etherscan ( eg. BscScan, PolygonScan, HecoInfo ) requires a different account to be created and hence a different set of API keys 🗝.

Which networks are API PRO endpoints applicable to?

The additional endpoints available under any API PRO subscription are only available to the Binance Smart Chain mainnet, and not supported on the testnet.

My API keys are not working, what can I do?

A technical glitch may have occurred in the key creation process. In this case, try deleting the key and generating a new one ✨​

If the issue still persists after using a freshly generated key, do reach out for us to have a closer look.
