API Overview

API Base URLhttps://codexapi.asia

Every public model endpoint requires an API key. The recommended header is:

Authorization: Bearer YOUR_API_KEY

Interactive testing

Open the Interactive API Explorer to inspect schemas, switch endpoints, and generate request snippets in several languages. Enter only your own API key; the explorer does not write authentication values into the documentation content.
