What you get#
Onekey exposes Steam as 14 endpoints behind one API key: 4 endpoints return one record (data is an object) and 10 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 Steam also works for the rest of the gaming category.
