GET /v1/models

The /v1/models endpoint returns all models that your API key has permission to use. Anyone inspects your request headers and returns the model list in the format that matches your client: OpenAI format by default, Anthropic format when Claude headers are present, or Gemini format when Google headers are present.

Authentication

Pass your API key using the header that matches the format you want in the response:

Auth method	Headers required	Response format
OpenAI (default)	`Authorization: Bearer YOUR_TOKEN`	OpenAI model list
Anthropic (Claude)	`x-api-key: YOUR_TOKEN` and `anthropic-version: 2023-06-01`	Anthropic model list
Gemini (Google)	`x-goog-api-key: YOUR_TOKEN`	Gemini model list

You can also pass the Gemini API key as a ?key=YOUR_TOKEN query parameter instead of the x-goog-api-key header.

Response (OpenAI format)

When you authenticate with a Bearer API key and no Claude or Gemini headers are present, the response follows the OpenAI models list format:

string

Always "list".

object[]

Array of model objects.

Show model object properties

string

The model identifier. Use this value in the model field of your requests.

string

Always "model".

integer

Unix timestamp for when this model entry was created.

string

The organization that owns the model. For example, "openai" or "system".

GET /v1/models/:model

Retrieve information about a specific model by its ID.

GET /v1/models/gpt-5.4

Returns a single model object in the same format as an entry in the data array above. When Claude headers are present, this endpoint returns the Anthropic model format instead.

Gemini format endpoint

To list models in Gemini format, you can use either of the following paths:

GET /v1/models with x-goog-api-key header
GET /v1beta/models with any valid API key

Example

curl https://api.anyone.ai/v1/models \
  -H "Authorization: Bearer YOUR_TOKEN"

curl https://api.anyone.ai/v1/models \
  -H "x-api-key: YOUR_TOKEN" \
  -H "anthropic-version: 2023-06-01"

curl "https://api.anyone.ai/v1/models?key=YOUR_TOKEN"

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_TOKEN",
    base_url="https://api.anyone.ai/v1",
)

models = client.models.list()
for model in models.data:
    print(model.id)

Example response (OpenAI format)

{
  "object": "list",
  "data": [
    {
      "id": "gpt-5.4",
      "object": "model",
      "created": 1715367049,
      "owned_by": "openai"
    },
    {
      "id": "claude-sonnet-4-6",
      "object": "model",
      "created": 1715367049,
      "owned_by": "anthropic"
    },
    {
      "id": "gemini-3.1-pro-preview",
      "object": "model",
      "created": 1715367049,
      "owned_by": "google"
    }
  ]
}

The models returned reflect what your specific API key is authorized to use. If you expect a model to appear but it does not, ask your Anyone administrator to grant access via the API key settings in the dashboard.
