Etherscan

As a means to provide equitable access to blockchain data, we've developed the Etherscan Ethereum Developer APIs to empower developers with direct access to Etherscan's block explorer data and services via GET/POST requests. Etherscan's APIs are provided as a community service and without warranty, so please use what you need and no more.     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 Ethereum mainnet, and not supported on testnets.   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.
