EZR KOS Open Platform is one of 2 APIs that [EZR](https://apis.io/providers/ezr/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include SCRM, Retail, Social Selling, and WeChat. The published artifact set on APIs.io includes a getting-started guide and authentication docs.

The KOS (Key Opinion Sales) open platform — EZR's separate integration surface for guide/associate-led social selling, documented in its own developer guide with its own hosts. It uses the same AppId / Sign / Timestamp / AppSystem signed-request scheme as the main Open Platform. EZR publishes the access model and request paths but no per-interface reference on the public portal.
