The Explorer API is a REST interface that exposes the full breadth of on-chain data from the Fuse blockchain. It follows a module-action query pattern similar to Etherscan: most endpoints accept module and action query parameters that determine the type of data returned. The API covers account balances, transaction history, token transfers, block data, smart contract source code, event logs, and network statistics — making it suitable for analytics dashboards, block explorers, and DApp backends that need rich chain data.

Query pattern

Explorer API endpoints use a module-action structure:
