AMTE Business Object OpenAPI (H3 Yun / 氚云 low-code BPM platform) is published by [Advanced Materials Technology & Engineering](https://apis.io/providers/advancedmaterialstechnologyengineering/) on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Low Code, Business Process Management, Workflow, Enterprise Integration, and Semiconductors. The published artifact set on APIs.io includes an OpenAPI specification and authentication docs.

A single anonymously-readable OpenAPI 3.0.1 document served from AMTE's own openapi.amteglobal.cn subdomain, describing one operation — POST /api/Object/LoadBizObjects — that pages business-object (form) records out of a low-code BPM/workflow engine. The parameter vocabulary (EngineCode, EngineSecret, SchemaCode, pageIndex, pageSize) and the MyResult/JsonResult envelope are the published integration contract of the Chinese low-code BPM platform H3 Yun (氚云, Aozhe/H3), so this is a vendor platform AMTE OPERATES as a tenant, not an API AMTE designed or markets. There is no developer portal, no signup, no documentation page and no publicly advertised program behind it: the contract was found only by resolving the openapi.* subdomain during STEP 0b contract discovery. Auth is a JWT bearer token declared in components.securitySchemes and applied globally; the Swagger UI at the host root is additionally wrapped in a username/password overlay, which no artifact here attempts to pass.
