API for obtaining the technical characteristics of phones and portable electronics, How?

Question

PHP

There is an online store selling smartphones, tablets, accessories.
For each item in Yandex.Market, there is a detailed technical description of the product.
There is a task - to automatically pull all this data through the API or in some other way.
Issue: Yandex replied that "For online stores, it is possible to use the content API only for the purpose of receiving reviews for the store and reviews for products."
Problem number 2: writing a parsing robot that will pull together all this information and the accompanying hemorrhoids is comparable in time to manual copy-paste, and the information, in fact, needs to be obtained one-time.
Who faced? Who can advise what?
