It will ask for
no credential variables read in the code
Where it talks to
no vendor host named in the codeAlso algolia.com — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · no network
What we could not test
what the tools do when called with real credentials

Connect it under the guard; read the third-party hosts first. The code names algolia.com as well as its own vendor. The guard pins the network to the hosts the honeypot saw.
