FAQ

Frequently Asked Questions.

Can the same API keys be used across different explorers?

Every block explorer built by zkSync Era Explorer ( 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?

Newly generated keys may take a moment to fully activate, please retry this in a moment! ✨

If the issue still persists after a few minutes or with a previously working key, do reach out for us to have a closer look.
