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.

What the API provides

## Marketplace evidence without building another scraper

### 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.

### Deep searches in one call

deep=true combines every sort order and price range for your keyword into one deduplicated list: 170 distinct sales for charizard psa 10 in our test.

### One key for every house

The same key returns Goldin, Fanatics Collect and Pristine Auction results in the same format, plus eBay sold listings and PSA data.

Request filters

## Start with a keyword, then narrow the page

Authentication uses the same CompSniper API key as every other endpoint. No MySlabs account is needed.

Important limitations

- MySlabs returns one page per search (up to 72 sales). Use deep=true for more, or narrow the keyword.
- Sold dates are days, not times.
- Deep searches take about 10 seconds and are limited to about 3 per minute per account.
- MySlabs matches keywords loosely: check the title and grade before using a price as a comp for one exact card.

Common workflows

## Built for resale tools and repeatable research

### Slab marketplace comps

MySlabs is a slab-only marketplace with low fees. Compare its sold prices with eBay to see where a card sells best after fees and shipping.

### Pricing your own listings

Check what the same card and grade recently sold for on MySlabs before you list there.

### Cross-house research

Pull MySlabs, Goldin, Fanatics Collect and Pristine results for one card and compare them in one format.
