Blockscout

About Blockscout

Blockscout provides blockchain explorer APIs, including a PRO API for querying on-chain data across multiple chains, as well as REST, JSON RPC, and GraphQL endpoints. The documentation covers API references for domains, metadata, cluster and aggregator services, and chain-specific endpoints for networks such as Arbitrum, Optimism, zkSync, Celo, Scroll, Shibarium, Stability, and Zilliqa, along with categories like addresses, blocks, smart contracts, tokens, transactions, and withdrawals.

The documentation includes a migration guide for developers moving from Etherscan's API, and a dev portal for obtaining API keys and managing usage. It also describes a separate endpoint for AI agents to set up data workstreams, and references additional services including a Merits API and a verification API.

This resource is aimed at developers building applications that need programmatic access to blockchain data, including those transitioning from Etherscan's API to Blockscout's offering.
