# GET /v1/models

> OpenAI-compatible model list endpoint. Returns all models available to the current API key with their supported API formats.

The `/v1/models` endpoint is an OpenAI-compatible interface that returns every model your API key can access. SDKs and clients use this endpoint to auto-discover available models and their supported API formats.

## Quick example

<CodeGroup>
  ```bash cURL theme={null}
  curl https://www.anyfast.ai/v1/models \
    -H "Authorization: Bearer YOUR_API_KEY"
  ```

  ```python Python theme={null}
  from openai import OpenAI

  client = OpenAI(
      api_key="YOUR_API_KEY",
      base_url="https://www.anyfast.ai/v1"
  )

  models = client.models.list()
  for model in models:
      print(f"{model.id} → {model.owned_by}")
  ```
</CodeGroup>

* Omitting the API key returns `401 {"error":{"message":"No token provided"}}`.<script src="/feedback.js" />
