In addition, I dont see that gau is using the apikey I provided.

the tool not working after installing it with this cmd

go install github.com/lc/gau/v2/cmd/gau@latest

WARN[0000] error reading config: open /home/duraid/.gau.toml: no such file or directory

how did you resolve this? Im with the same issue

Fix this crap

Just add the missing file in the PATH that is needed, with the default settings:
https://github.com/lc/gau/raw/master/.gau.toml

verbose = false

providers = ["wayback","commoncrawl","otx","urlscan"]

[urlscan]
  apikey = ""

@deljilal your error indicates that the file .gau.toml in your home directory /home/zabiiiiii is missing. Create the file .gau.toml and paste the content of thezakman's answer above into the file.
