# Universal API

> Obiguard Universal API provides a unified interface for accessing multiple LLM providers, simplifying integration and management.

Instead of building and maintaining separate integrations for each multimodal LLM,
you can use a single, unified API to access models from OpenAI, Anthropic, Meta, Cohere,
Mistral, and over 100 models across 15+ providers.

## Obiguard Uses the OpenAI API Standard

The Obiguard API leverages its robust open-source AI Gateway to translate all
incoming requests into the OpenAI API format, ensuring responses are fully OpenAI-compatible.

## Seamlessly Switch Between Providers

<Tabs>
  <Tab title="Python SDK">
    ```python theme={null}
    from obiguard import Obiguard

    # Calling OpenAI
    client = Obiguard(
      provider = "openai",
      Authorization = "sk-xxxxx"
    )

    response = obiguard.chat.completions.create(
      messages = [{ "role": 'user', "content": 'Hello' }],
      model = 'gpt-4'
    )

    # Switching to Anthropic
    client = Obiguard(
      provider = "anthropic",
      Authorization = "sk-ant-xxxxx"
    )

    response = obiguard.chat.completions.create(
      messages = [{ "role": 'user', "content": 'Hello' }],
      model = 'claude-3-opus-20240229'
    )
    ```
  </Tab>
</Tabs>

## Integrating Local or Private Models

Obiguard can connect to and monitor your locally or privately hosted LLMs,
provided the model is compatible with one of the 15+ providers supported by Obiguard and its URL is accessible.

Just set the `custom_host` parameter along with the provider name,
and Obiguard will manage communication with your local model.

<Note>
  When using `custom_host`, make sure to include the version segment (e.g., /v1) in the URL.
  Obibuard will automatically add the correct endpoint path (`/chat/completions`, `/completions`, or `/embeddings`).

  For Ollama models, this process is different. See documentation for details.
</Note>

### Multimodality

Obiguard offers seamless integration with multimodal models using the same unified API, enabling support for vision, audio, image generation, and additional advanced capabilities across multiple providers.
