What you get#
Onekey exposes AliExpress as 9 endpoints behind one API key: 1 endpoint return one record (data is an object) and 8 endpoints return a list (data is an array). Every answer uses the same envelope (success, data, metadata, error), the cost is reported in metadata.credits_charged, and fields are mapped onto the unified schema so the code you write for AliExpress also works for the rest of the e-commerce & marketplaces category.
