[VoiceOps] LRN API Source

Greetings all,
 We've got an internal tool that lets my NOC staff query extended LRN on 
numbers. They use this for checking the numbers current carrier, Verifying 
a number after it ports (In or out)..etc. This same tool also pulls CNAM 
from a few sources so they can easily test "Wrong caller ID" tickets.
 Does anyone have any good leads on someone that has a good non-cached LRN 
 We've tried two thus far with poor results.
 1. "CallWithUs", Real time results, But cached for 24 hours after the 
first request. So if we wanted to check a number more then once a day, We 
get the same results.
 2. ThinQ. Results returned are either cached, Or perhaps outdated. 
Querying a number after it ports returns the old LRN. Results do not update 
until 24 hours after port. Since we have a decent bit of traffic on ThinQ, 
And a decent relationship with them I opened a ticket to see if it could be 
a adjusted. First was told that LRN takes 24 hours to update. And that was 
normal. I pushed back on the obvious canned and incorrect response and they 
"made some changes" which did nothing. Finally they admitted they could not 
return real-time results.
 Many of my upstream carriers are using Syniverse as their LRN source. So I 
reached out to them. Found my volume (~20 queries a day) is too low for 
them. And they don't offer any type of HTTP API, Understandably on both 
 Example output of our internal tool. (Queried 13212051100)
