This is exactly my point. Sorry if I was not clear on my OP.

We are using Seller API to get different product information, while their API provides base work for communicating with their endpoint, you'll have to implement your own system to use that, and handle the absurd unreliability of their API's rate limiter, and the spider web of API callbacks to get information that you require.
