The problem it solves

If you sell a digital product with license keys, you need a fast way to confirm a key is real before granting access. Checking each one by hand isn't practical once you have more than a handful of customers.

Who it fits

Digital product creators and software sellers using Gumroad who need to gate access by license key.

How it works

  1. A request comes in with a license key and product ID
  2. Gumroad is asked to confirm whether that key is valid for the product
  3. A response is sent back saying whether the key is valid
What you get

License checks that happen instantly

Every license key gets checked against your Gumroad records in an instant, so access to your product stays tied to the right customer.

What you get

An instant valid or invalid response for any license key submitted.

What you need

A Gumroad seller account.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
