List Models

Retrieve a list of available models from the Unbound gateway.

Endpoint

GET /v1/models

Request Headers

Header	Type	Required	Description
`Authorization`	string	No	Bearer token with your API key. Optional — the endpoint returns the public model catalog without authentication. Pass your key to receive your organization’s filtered model list.

Example Request

curl -X GET 'https://api.getunbound.ai/v1/models' \
  -H "Authorization: Bearer YOUR_API_KEY"

Example Response

The catalog updates frequently — the numbers below are illustrative. Always read the live endpoint for canonical pricing, max_tokens, and capability flags.

{
  "object": "list",
  "data": [
    {
      "id": "anthropic/claude-sonnet-4-20250514",
      "created": 1777913942,
      "pricing": {
        "input_token_price": "…",
        "output_token_price": "…",
        "cache_read_price": "…",
        "cache_write_price": "…"
      },
      "parameters": {
        "context_window": 200000,
        "max_tokens": 8192,
        "supports_prompt_caching": true,
        "supports_computer_use": true,
        "supports_images": true
      }
    }
  ]
}

Don’t hardcode max_tokens, pricing, or the model set from this page. Call GET /v1/models at request time — the gateway exposes ~60 models today and the catalog grows as new providers and model versions ship.
