# swarms API Documentation

The swarms API provides endpoints to interact with various language models, manage agent configurations, and handle token counting. This documentation covers the available endpoints, input and output models, and detailed examples for each endpoint.

URL: `https://api.swarms.world`

## Key Features

- Dynamic Model Switching: Easily switch between different language models based on user input.
- Token Counting: Efficiently count tokens using the tiktoken library.
- Agent Configuration: Configure and run agents with detailed settings for various tasks.
- CORS Handling: Support for Cross-Origin Resource Sharing (CORS) to allow web-based clients to interact with the API.

## Functions

### count_tokens

The `count_tokens` function counts the number of tokens in a given text using the `tiktoken` library.

**Parameters:**

- `text` (`str`): The text to be tokenized and counted.

**Returns:**

- `int`: The number of tokens in the text.

**Example Usage:**

```python
text = "This is a sample text to count tokens."
token_count = count_tokens(text)
print(f"Token count: {token_count}")
```

### model_router

The `model_router` function switches to the specified language model based on the provided model name.

**Parameters:**

- `model_name` (`str`): The name of the model to switch to.

**Returns:**

- An instance of the specified language model.

**Example Usage:**

```python
model_name = "OpenAIChat"
model_instance = model_router(model_name)
```

## Additional Information and Tips

- **Error Handling**: Ensure robust error handling by catching exceptions and returning meaningful HTTP status codes and messages.
- **Model Selection**: When adding new models, update the `model_router` function and the `/v1/models` endpoint to include the new model names.
- **Token Management**: Keep track of token usage to optimize API costs and manage rate limits effectively.
