Best When

You need transaction history, ABI lookup, or token transfer data for an Ethereum address without running your own indexer.

Avoid When

You need to write to the blockchain, require real-time streaming, or are working with non-Ethereum chains.

Use Cases

• Fetching complete transaction history for any wallet address
• Retrieving verified smart contract ABI for dynamic interaction
• Monitoring ERC-20/ERC-721 token transfers for a wallet
• Getting current gas price estimates for transaction planning
• Looking up contract verification status and source code

Not For

• Sending transactions (read-only API)
• Real-time streaming of blockchain events
• Non-Ethereum chains (use BSCScan, PolygonScan for other EVM chains)
