The complete API for MegaETH data
Query MegaETH balances, transactions, tokens, contracts, and logs using the same Etherscan API that powers MegaETH Etherscan, with one API key and chainid=4326.
Why teams choose Etherscan API for MegaETH data
Explorer-grade blockchain data for teams that need accuracy, coverage, scale, and a clear path to multichain data from day one.
The first-choice API for MegaETH data
When teams need blockchain data they can defend in front of users, finance, or compliance, they start with the Etherscan API.
The reference layer for onchain data
Built with MegaETH Etherscan data, the API is used as a reference point to verify balances, transfers, internal transactions, and contract activity on MegaETH.
Accuracy that holds up under scrutiny
Capture edge cases many providers miss and reduce time spent reconciling mismatched records across tools.
One integration, 60+ chains
Same endpoints, same structure, one API key across MegaETH and other chains. Just set chainid=4326 for Mainnet or chainid=6343 for Testnet.
MegaETH data through a familiar API
Use the same request parameters, response formats, and API conventions that power MegaETH Etherscan and other Etherscan-supported explorers.
The default for mission-critical data
If blockchain data is mission-critical, Etherscan API is the default choice for teams that need accuracy and reliability.
How to start querying MegaETH with Etherscan API
Get an API key, set the MegaETH chain ID, and call the same endpoint structure used across 60+ EVM chains.
Get your API key
Create an Etherscan API key and use it for MegaETH Mainnet, Testnet, and other supported chains.
Set the MegaETH chain ID
Pass chainid=4326 for MegaETH Mainnet or chainid=6343 for MegaETH Testnet in Etherscan API requests.
