I'm in need of a site which offers random numbers through an API. I've found random.org, which looks nice, but it's missing one feature I really need: The ability for people to verify the random number.
Simple example of what I'm looking for:
Player A has number 0
Player B has number 1
I do an API call for a random number between 0 and 1.
With the random number returned, I have a unique ID I can give to both players. They can then use this to verify that the random number was generated by the site I link, and that the 'winning' number presented is the one generated.
The site must be independent, so while making one would be trivial it needs to be 'trusted' by the people involved. Hosting it myself would offer no guarantee of manipulation.
The number of calls needed would be small.
Any thoughts?
