StockX

StockX is a global online marketplace for sneakers, streetwear, electronics, collectibles, and trading cards, operating on a live bid/ask model similar to a stock exchange. The StockX Public API (v2.0.0) lets approved developers in the StockX Developer Program search the product catalog, read live market data (bids/asks), create and manage seller listings individually or in bulk via asynchronous batch operations, and track sales orders and their shipping documents. Requests authenticate with an x-api-key header plus an OAuth 2.0 bearer token issued by StockX's Auth0 tenant. StockX was surfaced as a portfolio company of Battery Ventures and GV.

StockX publishes 4 APIs on the APIs.io network, including Batch API, Catalog API, Listings API, and 1 more. Tagged areas include Company, Marketplace, E-Commerce, Sneakers, and Streetwear.

StockX’s developer surface includes documentation, API reference, getting-started guide, authentication, changelog, engineering blog, support, and 21 more developer resources.

  description: Batch APIs enable a user to create, update, delete listings in bulk. Batch APIs are asynchronous in nature
    and we provide mechanisms to poll the API so that you can keep track of the batch completion.  Once a batch is successfully
    completed, you can view the status of each individual listing.  We track each individual listing inside a batch separately
    so you can have scenarios where some listings succeed and some fail in a single batch.
