Is there any interest in a SECURE 0-Confirm Bitcoin payment solution for playerup?

Hello!

I was reading this thread about people who were super confused as to how their Bitcoin Transactions got reversed. Is there an interest in a tool (sold to sellers for probably around $15 for basic functionality) where you enter a txid and it does some basic double spend checks/gives a breakdown of how risky accepting the transaction before confirmations is?

This is similar to what BitPay does to make sure that their Zero Confirm system doesn't get doublespent, and it would protect sellers using the tool from getting scammed.

I could probably write it as a webapp accessible over Tor, or an electron app.
