# Gemini-Compatible OpenAI Model List

# Gemini-Compatible OpenAI Model List

```
GET /v1beta/openai/models
```

This endpoint is a compatibility bridge:

* the auth style can be Gemini-like
* the response shape is still OpenAI-style model-list JSON

This page only documents behavior that was revalidated against Crazyrouter production on `2026-03-23`.

## When to use it

* your client prefers `?key=`
* your middleware already uses `x-goog-api-key`
* you want an OpenAI-style `list + data[]` response rather than native Gemini model metadata

If you are using a normal OpenAI-compatible client, prefer [GET /v1/models](/ru/chat/openai/models).

## Authentication

This recheck confirmed that all three of the following work:

```http theme={null}
Authorization: Bearer YOUR_API_KEY
```

```http theme={null}
x-goog-api-key: YOUR_API_KEY
```

```text theme={null}
GET /v1beta/openai/models?key=YOUR_API_KEY
```

## Request examples

<CodeGroup>
  ```bash cURL theme={null}
  curl "https://api.crazyrouter.com/v1beta/openai/models?key=YOUR_API_KEY"
  ```

  ```bash cURL with Header theme={null}
  curl https://api.crazyrouter.com/v1beta/openai/models \
    -H "x-goog-api-key: YOUR_API_KEY"
  ```
</CodeGroup>

## Current production findings

In the `2026-03-23` production recheck:

* the `?key=` request returned `200`
* the `x-goog-api-key` request returned `200`
* the top-level `object` was `list`
* the top-level `success` was `true`
* the current model count was `541`
* common fields inside `data[]` included:
  * `id`
  * `object`
  * `created`
  * `owned_by`
  * `supported_endpoint_types`

## Response example

```json theme={null}
{
  "object": "list",
  "success": true,
  "data": [
    {
      "id": "gpt-5.5",
      "object": "model",
      "created": 1700000000,

      "object": "model",
      "created": 1700000000,

## Field notes

| Field                      | Type    | Meaning                               |
| -------------------------- | ------- | ------------------------------------- |
| `data[]`                   | array   | Models available to the current token |
| `id`                       | string  | Model identifier                      |
| `owned_by`                 | string  | Upstream source or owner label        |
| `supported_endpoint_types` | array   | Supported API styles for the model    |
| `object`                   | string  | Always `list`                         |
| `success`                  | boolean | Whether the request succeeded         |

<Note>
  Read the path meaning of `supported_endpoint_types` from `supported_endpoint` in `GET /api/pricing`. At the moment, `openai` maps to `POST /v1/chat/completions`, `anthropic` maps to `POST /v1/messages`, and only `openai-response` maps to `POST /v1/responses`. Claude currently exposes `openai` + `anthropic`, not `openai-response`.
</Note>

<Note>
  This endpoint does not return only Gemini models. It returns the OpenAI-style model list visible to the current token, but exposes it through a Gemini-friendly access path.
