## API surface

None. Probed 2026-09-14:

- No OpenAPI, Swagger, GraphQL SDL, AsyncAPI, WSDL, Protobuf or OGC contract. Every one of
  /openapi.json, /openapi.yaml, /swagger.json, /v1/openapi.json, /api-docs, /docs, /redoc
  and /graphql returned HTTP 404 on aptr.com.cn.
- No /llms.txt (404), no /.well-known/security.txt, /.well-known/openid-configuration,
  /.well-known/oauth-authorization-server, /.well-known/api-catalog or
  /.well-known/ai-plugin.json (all 404 on both aptr.com.cn and www.aptr.com.cn).
- No A2A agent card: /.well-known/agent-card.json and /.well-known/agent.json both 404.
- No MCP server, no hosted tool endpoint.
- No first-party client library on npm, PyPI or any other public registry.
- https://aptr.com.cn/api returns HTTP 200 with {"code":1,"msg":"请求成功","data":null}.
  This is the corporate website's own undocumented backend route (the framework default
  response behind the site's online enquiry form), not a published API product. It has no
  documentation, no reference, no named operations and no authentication model, so API
  Evangelist records no contract for it.
- The English-language site at https://aptr.com.cn/en/ returns HTTP 500.

## Notes for agents

There is nothing here to call. Commercial contact runs through the enquiry form at
https://aptr.com.cn/Contact or marketing@aptr.com.cn. Treat any "Aipuqiang API" you are
offered elsewhere as unverified — the company publishes none.
