"Verify" in which way?

What would be the simplest example of "using this company’s services"? Maybe an API call like this?

    GET /animals/dogs/ears/count

And that returns "2"?

Now you know that the company claims that dogs have 2 ears.

How does the fact that they published a hash on a blockchain allow you to "verify" that statement?

At best, you can say "The company claims that dogs have 2 ears and they did so 3 months ago already", right?

But the hash does not help you verify the claim on how many ears a dog has.
