Hello all and thank you for the reply,
I think I know the issue. I am doing a bulk request, which is not recommended. In addition, I do not think I spread my request across time and may have broken the 1 second limit between each request. Finally, and I doubt this is the case since the block of code failed, but I should be caching my responses.
Again, block of code failed on first request and so need to check to see if my IP has been blocked for breaking the policy on the first two points. I will review the policy (should have done that first), and then alter my app to manage requirements. Once done, do either of you know how to get my IP unblocked lol?
Thanks again for the input, very helpful to see the policy of usage.
PS. Also did not follow some of the requirements and so maybe not blocked, will have to try again
