Not sure if you meant this sarcastically, I guess you do. However, if such a tool would exist, taking away the hassle of due diligence or at least beforehand (before starting due diligence) prove you are a credible investor it could save a ton of work. If you had some way of knowing that your due diligence work and accompanying costs would not go to waste because of the opposing party not checking out, that would be value. Note it doesn't need to give an accurate, to the dollar net worth as long as it flags you as credible investor.

Not saying anything about the complexity of building such a tool.
