Why teams choose Etherscan API for Sonic 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 Sonic 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 SonicScan data, the API is used as a reference point to verify balances, transfers, internal transactions, and contract activity on Sonic.

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 Sonic and other chains. Just set chainid=146 for Mainnet or chainid=14601 for Testnet.

Sonic data through a familiar API

Use the same request parameters, response formats, and API conventions that power SonicScan 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.
