# List models

`GET /models`

Lists the models available to your API key.

The response includes model IDs that can be used in chat completion and embedding requests.

By default, this endpoint follows the OpenAI-compatible models-list shape. Doubleword also supports optional query-string extensions for model discovery: `group` filters to comma-separated group UUIDs, `available_for_realtime` filters by whether realtime traffic is allowed for the model, and `include_reasoning_capabilities=true` adds the reasoning efforts supported by every provider behind each model.

## Query parameters

- `group` string
- `available_for_realtime` boolean
- `include_reasoning_capabilities` boolean
