Looks like this is related to the discontinuation of the Censys free plan after the first 60 days: https://support.censys.io/hc/en-us/articles/360042832492-Create-a-Free-Censys-Search-Account

Will add a warning to the readme. If you need to use it, you'll need to pay for a pro account or create a new free accounts (and your API key will work for the first 60 days only)

As the repository owner replied above, the reason why API Key is invalid seems to be more than 60 days after the creation date of the Censys Free plan account.

I had the same issue, so just now I created a new account and tested it, and the valid result was returned.
