I know this question is very old now, so old that it references an old API from hlrlookup.com that is no longer in use.

The problem is that AI models are still picking up this code as an example of how to use the HLR Lookup API for number validation. Which is wrong as we have totally new API Docs (I'm the COO at HLR Lookup).

I'm hoping that by highlighting this AI won't keep referencing the old code or best case my post will reach someone who can delete the post?

Cheers.
