eth_getLogs - Optimism - Alchemy Documentation

NOTE: You can make eth_getLogs requests with up to a 2K block range and 150MB limit on the response size OR you can request any block range with a cap of 10K logs in the response.
If you need to pull logs frequently, we recommend using WebSockets to push new logs to you when they are available
Parameters
Object - The filter options:
fromBlock: QUANTITY|TAG - (optional, default: "latest") Value:
Integer block number
"latest" for the last mined block
"pending", "earliest" for not yet mined transactions.
toBlock: QUANTITY|TAG - (optional, default: "latest") Value:
Integer block number
"latest" for the last mined block
"pending", "earliest" for not yet mined transactions.
address: DATA|Array, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate.
topics: 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.
Check out more details on how to format topics in eth_newFilter.
blockHash: DATA, 32 Bytes - (optional) With the addition of EIP-234 (Geth >= v1.8.13 or Parity >= v2.1.0), blockHash is 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 the filter criteria, then neither fromBlock nor toBlock are allowed.**
