Seems technically possible - example.com/12_3456 would calculate out pi, read 12 digits starting at position 3456, then convert those digits to ascii and you'd have your result. Given how far into the digits pi you'd have to go to find the exact right sequence that matches, eg, https://google.com https://google.com, though, I suspect the resulting position number would be longer than the original url! Also, conceptually, it seems like you're not so much using pi as a database as you are using it as an encoding mechanism: turning "abc.com" into a string of numbers whose length is relative to the original string. At that point you might as well pick an easier encoding, like base64. :)
