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.

Authentication

This recheck confirmed that all three of the following work:

Authorization: Bearer YOUR_API_KEY

x-goog-api-key: YOUR_API_KEY

GET /v1beta/openai/models?key=YOUR_API_KEY

Request examples

curl "https://api.crazyrouter.com/v1beta/openai/models?key=YOUR_API_KEY"

curl https://api.crazyrouter.com/v1beta/openai/models \
  -H "x-goog-api-key: YOUR_API_KEY"

Response example

{
  "object": "list",
  "success": true,
  "data": [
    {
      "id": "gpt-5.5",
      "object": "model",
      "created": 1700000000,
      "owned_by": "openai",
      "supported_endpoint_types": ["openai"]
    },
    {
      "id": "claude-opus-4-8",
      "object": "model",
      "created": 1700000000,
      "owned_by": "anthropic",
      "supported_endpoint_types": ["openai", "anthropic"]
    },
    {
      "id": "gemini-3.1-pro",
      "object": "model",
      "created": 1700000000,
      "owned_by": "google",
      "supported_endpoint_types": ["openai", "gemini"]
    }
  ]

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

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.

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.
