OpenRouter

Obiguard provides a robust and secure gateway to facilitate the integration of various Large Language Models (LLMs) into your applications, including OpenRouter. With Obiguard, you can take advantage of features like fast AI gateway access, observability, prompt management, and more, all while ensuring your provider credentials stay in Obiguard and callers authenticate with access keys.

Obiguard SDK Integration with OpenRouter Models

Obiguard provides a consistent API to interact with models from various providers. To integrate OpenRouter with Obiguard:

1. Install the Obiguard SDK

Add the Obiguard SDK to your application to interact with OpenRouter AI’s API through Obiguard’s gateway.

Python SDK

pip install obiguard

2. Initialize Obiguard with an access key

To use OpenRouter with Obiguard, get your API key from here. Add it to Obiguard as a provider credential, then create an access key for the agent or project that will call it.

Python SDK

from obiguard import Obiguard

client = Obiguard(
  obiguard_api_key="ak***",  # Your Obiguard access key
)

3. Invoke Chat Completions with OpenRouter

Use the Obiguard instance to send requests to OpenRouter.

Python SDK

completion = client.chat.completions.create(
  messages= [{"role": 'user', "content": 'Say this is a test'}],
  model= 'mistral-medium'
)

print(completion)

Open Router Tool Calling

Tool calling feature lets models trigger external tools based on conversation context. You define available functions, the model chooses when to use them, and your application executes them and returns results. Obiguard supports Open Router Tool Calling and makes it interoperable across multiple providers.
