Question - Could someone help me with WORKING API KEY

[profesionalleet1337]

Hello Friend ! Your tool looks unique, and I would very much like to test it successfully.
I'll try to be brief, I apologize in advance for the bad grammar.

• I looked at how it is set up, a lot of opinions too, but I have the following problem: I use the application from google cloud shell (I did not find any instructions how to set it up from there) BUT everything works as it should, there are no problems with the set-up, BUT when I enter an email for research, after searching it gives me the following message: ,Not compromised no matter what > whatever email I wrote, it gives me no result". I looked at quite a few of the other users' errors, I also noticed that this line with this command "scylla.so error: sample123@gmail.com - Expecting value: line 2 column 1 (char 1)" also appears. Initially it shows that this command "scylla" works, but after research any mail - it saying this eror.
  I've read all the comments and your guidance, and maybe I'm coming to the conclusion that I need to put in some kind of API key, here I'm not clear what I need to do, especially in google cloud shell, where should I put it? I created an account in LOCALHost, it generates an API key for me, but I'm not sure where and what I should replace in the tool itself? I will be extremely grateful if you tell me what exactly and where I should replace/enter so that will gives me a result in the research. (I remind that I use it from Google Cloud Shell).

Update:
I found my mistake, and figured out where I should put this API CODE
-> The problem is that there is no free one anywhere that works and displays any passwords, I tried with the one on intelx.io ( there is a free API ) , after placing it, it still does not display the passwords (And when I tried and checked on the site, it displayed for basic email passwords, for example: johnsmith@gmail.com)

• Well, is there somewhere a free api key with which I can check some passwords, can someone help me with providing one? I looked at all the possible sites, nothing works - anywhere in the tool?
