Price plus shipping
Every sale has the price the buyer paid, with the 1% buyer's premium, and the shipping they paid when the seller charged it, so you see the full cost.
Sold slabs with shipping paid
MySlabs sold prices through one API.
Short answer: MySlabs has no public API for sold data, so use GET /v1/myslabs/sold. One keyword returns up to 72 recent MySlabs sales with the price the buyer paid (MySlabs' 1% buyer's premium included), the shipping they paid, the sold date, whether it sold at a fixed price or at auction, grading company, grade and a link to the slab. Add deep=true for a few hundred sales of the same keyword in one call.
