Response limit
There is a response limit for each RPC request. Trying to call the eth_getLogs method may increase the content size, which can be brought down by refining the request, such as reducing the block range.
Default limit: 2 Megabytes (MB)
Error code: -32000
Error message: Response size should not be greater than 2097152 bytes
Example:
Usage quota
