RF OpenAI endpoint

Supported route

MVP integration steps

  1. RF operations creates a downstream customer config with API key, model allowlist, markup, and monthly RMB limit.
  2. Customer replaces only the OpenAI base URL and Authorization key.
  3. RF forwards to Tencent Cloud TokenHub with the supplier key stored only on the server.
  4. Non-streaming calls are billed from upstream usage; streaming calls are captured when usage is present or marked for reconciliation.
