- There is no base URL to call. Every contract-discovery path probed on 2026-09-05
  (/openapi.json, /openapi.yaml, /swagger.json, /v1/openapi.json, /api-docs, /docs, /redoc,
  /graphql, /apis.json, /apis.yml, /llms.txt and the full /.well-known set) returned HTTP 404 on

- No A2A agent card, no MCP server, no AsyncAPI or webhook surface, and no first-party client library on npm, PyPI,
  RubyGems, crates.io, Packagist or NuGet (all six searched for "500net" on 2026-09-05; zero

- The correct route to an integration is the contact form / service@500net.com.tw, not a self-serve
  developer signup.
