eth_getLogs

Returns an array of all logs matching a given filter object.
Parameters
Params - a string array containing (required):
Object - The filter options:
fromBlock(string, optional). QUANTITY|TAG - (optional, default: "latest") integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.
toBlock(string, optional). QUANTITY|TAG - (optional, default: "latest") integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.
address(array of hex string, optional). DATA|Array, 20 Bytes - (optional) contract address or a list of addresses from which logs should originate.
topics(array of hex string, optional). Array of DATA, - (optional) array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with “or” options.
blockhash(hex string, optional). DATA, 32 Bytes - (optional, future) with the addition of EIP-234, blockHash will be a new filter option which restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to fromBlock = toBlock = the block number with hash blockHash. If blockHash is present in in the filter criteria, then neither fromBlock nor toBlock are allowed.
Returns
Array - Array of log objects, or an empty array if nothing has changed since last poll.
For filters created with eth_newBlockFilter the return are block hashes (DATA(hex string), 32 Bytes), e.g. ["0x3454645634534..."].
For filters created with eth_newPendingTransactionFilter the return are transaction hashes (DATA(hex string), 32 Bytes), e.g. ["0x6345343454645..."].
For filters created with eth_newFilter logs are objects with following params:
removed(boolean). TAG - true when the log was removed, due to a chain reorganization. false if its a valid log.
logIndex(hex string). QUANTITY - integer of the log index position in the block. null when its pending log.
transactionIndex(hex string). QUANTITY - integer of the transactions index position log was created from. null when its pending log.
transactionHash(hex string). DATA, 32 Bytes - hash of the transactions this log was created from. null when its pending log.
blockHash(hex string). DATA, 32 Bytes - hash of the block where this log was in. null when its pending. null when its pending log.
blockNumber(hex string). QUANTITY - the block number where this log was in. null when its pending. null when its pending log.
address(hex string). DATA, 20 Bytes - address from which this log originated.
data(hex string). DATA - contains one or more 32 Bytes non-indexed arguments of the log.
topics(array of (hex string)). Array of DATA - Array of 0 to 4 32 Bytes DATA of indexed log arguments. (In solidity: The first topic is the hash of the signature of the event (e.g. Deposit(address,bytes32,uint256)), except you declared the event with the anonymous specifier.)
