Steps
Complete StockX developer onboarding to get an approved application with an auto-generated x-api-key
Call the v2/catalog/search endpoint against the api.stockx.com/v2 base URL to search products by keyword
Include both an OAuth Bearer access token and the x-api-key header on every request
Retrieve product variants (sizes) for a matched product to get variant-level identifiers needed for listings and orders
Respect the published rate limits when paging through large catalog searches
Known gotchas
Both the Bearer access token and the x-api-key header are required together; supplying only one results in an authentication failure
Some catalog sub-resources, such as market data, have been reported as unreliable in practice, so validate responses before depending on them in production
