Routescan API documentation

Routescan is a multichain explorer, search, API and analytics platform spanning dozens of EVM chains, Ethereum, Avalanche, Plasma, Blast, Berachain, Mantle, Metis and many more. The Developer APIs expose that indexed on-chain data directly through simple HTTP requests.

We've unified all 70+ supported chains under a single account and API key system. Your app becomes multichain simply by updating the chainid parameter to support all indexed chains.

Start building

Address balance & holdings

Native balance plus full ERC-20 and NFT holdings for any address.

Transactions & transfers

Normal, internal and token transfer history for any address.

Token info & holders

Token metadata, supply, prices and the ranked list of top holders.

Event logs

Query and filter contract event logs by address, topic and block range.

There are two ways to consume the data, both served from the same base URL and sharing the same authentication and rate limits:

  • High-speed REST API, purpose-built endpoints that return indexed results in near real time (balances, token holdings, transfers, transactions and more).
  • Etherscan-compatible API, the familiar module/action query format, so existing Etherscan-based code works against any chain Routescan indexes with minimal changes.
