Any way to find out my Amazon Product API Limits

I was given an Amazon awsAccessKeyId and awsSecretKey,

also our company has affiliated with Amazon, we get a Associate Tag​.

And I was told we may get higher API limits, because we are affiliated.

But I don't have any detailed info about the API limits,

I want to know how many calls i can make in a second

Is there any way I could check our API Key status?

The call i use will be check product info like:

Service=AWSECommerceService
&Operation=ItemLookup&ItemId=[ID]
&IdType=ASIN
.....
