  detail: >-
    3721zh.com markets "API接口" (API interfaces) on its own About page as one delivery mode of its
    merchant SaaS and runs a live first-party gateway at gw.3721zh.com, but publishes no developer
    portal, reference or spec anywhere; the only route to an integration is the 商户入驻
    merchant-onboarding lead form and the 400-720-0000 sales line.
