title: Use the scoped OAuth token
description: Execute inference calls using the user-provided OAuth access token.
---

The `access_token` returned by `/oauth/token` is a standard Zorveus API key (`zrv_...`). Pass it directly in the `Authorization: Bearer zrv_...` header, the official Zorveus SDK constructors, or OpenAI SDK `apiKey` parameters.
