Hello again,
Version 1.0.2 is out now. The problem should be resolved. Thank you again for posting and apologies for the delay.
If you set API memoizing to 0 (not memorizing), then it might impact performance, the option is there only because some people experience non-expiring transients for unknown reasons. If you are not facing any issues then it’s best to leave the value at its default. This caches the public outputs of the API so that multiple requests do not slow down your system too much (But, in any case, this should not be your only protection against DoS attacks).
with regards
