ETH RPC
The Blockscout ETH RPC API supports 3 methods in the exact format specified for Ethereum nodes, see the Ethereum JSON-RPC Specification for more details. These methods are provided for your convenience. In general, custom RPC methods are recommended.
The following 3 methods are supported:
eth_blockNumber
eth_getBalance
eth_getLogs
In the following examples we use the Ethereum mainnet with the base instance url https://blockscout.com/eth/mainnet
. When sending a request add /api/eth-rpc
to the end of the base url.
eth_blockNumber
Returns the latest block number in the chain in hexidecimal format. No params are needed. Type: POST
Example
eth_getBalance
Returns the balance of a given address in wei. Note the earliest
parameter does not work as expected because genesis block balances are not currently imported. Parameters are required.
Required Parameters
Type
POST
Data (string)
20 Byte address to check balance
Quantity or Tag (string)
Integer value of a block number, or a tag "latest" for the most recent block.
Example
eth_getLogs
Returns an array of logs matching a specified filter object. Params are optional based on data you want to receive. From more information, see this post on eth_getLogs.
Note: Never returns more than 1000 log entries. You can use pagination options to request the next page. Pagination options params: {"logIndex": "3D", "blockNumber": "6423AC"} which include parameters from the last log received from the previous request. These three parameters are required for pagination.
