# API reference overview

> OmniMux gateway OpenAPI — protocol entrypoints and auth.

Call the gateway with a **Bearer token**. Default Base URL:

```text theme={null}

```

## Main entrypoints

| Capability       | Method         | Path                                     |
| ---------------- | -------------- | ---------------------------------------- |
| Chat Completions | `POST`         | `/v1/chat/completions`                   |
| Responses        | `POST`         | `/v1/responses`                          |
| Claude Messages  | `POST`         | `/v1/messages`                           |
| Gemini           | `POST`         | `/v1beta/models/{model}:generateContent` |
| List models      | `GET`          | `/v1/models`                             |
| Images           | `POST`         | `/v1/images/generations`                 |
| Video (async)    | `POST` / `GET` | `/v1/video/generations`, `/v1/videos`, … |

Endpoint pages in the sidebar are generated from `openapi/relay.json` and support try-it playgrounds where enabled.

## Authentication

```http theme={null}
Authorization: Bearer sk-xxxxxxxx
```

See [Authentication](/en/guides/authentication).

## Async tasks

Image and video APIs often return a `task_id` first; poll for status and results. Field names follow each endpoint schema.

<Tip>
  Unimplemented placeholder ops are stripped from the public spec. If a model appears in the console but not here, trust live `GET /v1/models` and channel config.
