This API is provided for developers transitioning applications from Etherscan to BlockScout and applications requiring general API and data support. It supports GET and POST requests.
What is instance_base_url? The examples on each RPC module page use https://instance_base_url/api?... as a placeholder. Replace instance_base_url with the hostname of the Blockscout explorer for the chain you want to query. There is no single global host for the per-instance RPC API. Each chain has its own instance.Common examples:For the full list of hosted instances and their URLs, see chains.blockscout.com. For self-hosted deployments, use your own explorer hostname.Example query — Sepolia, account.listaccounts:https://eth-sepolia.blockscout.com/api?module=account&action=listaccounts&page=2&offset=5
For a single multichain endpoint (one host, chain_id parameter), use the PRO API instead of per-instance URLs.
The following modules are supported. Click through to see specific endpoints and parameters.
