# CometAPI

> Learn how to use CometAPI models in Agno.

CometAPI is a platform for providing endpoints for Large Language models.

See all CometAPI supported models and pricing [here](https://api.cometapi.com/pricing).

## Authentication

Set your `COMETAPI_KEY` environment variable. Get your API key from [here](https://api.cometapi.com/console/token).

<CodeGroup>
  ```bash Mac theme={null}
  export COMETAPI_KEY=***
  ```

  ```bash Windows theme={null}
  setx COMETAPI_KEY ***
  ```
</CodeGroup>

## Example

Use `CometAPI` with your `Agent`:

<CodeGroup>
  ```python agent.py theme={null}
  from agno.agent import Agent
  from agno.models.cometapi import CometAPI

  agent = Agent(model=CometAPI(), markdown=True)

  # Print the response in the terminal
  agent.print_response("Explain quantum computing in simple terms")

  ```
</CodeGroup>

`CometAPI` extends the OpenAI-compatible interface and supports most parameters from the [OpenAI model](/concepts/models/openai).

## Available Models

CometAPI provides access to 300+ AI models. You can fetch the available models programmatically:

```python theme={null}
from agno.models.cometapi import CometAPI

model = CometAPI()
available_models = model.get_available_models()
print(available_models)
```
