Microsoft Agent Framework | Doubleword Inference API

The Microsoft Agent Framework is Microsoft's SDK for building AI agents and multi-agent systems. It supports custom OpenAI-compatible endpoints natively.

Install

pip install agent-framework-openai agent-framework-core

Configure

from agent_framework import Message
from agent_framework_openai import OpenAIChatCompletionClient
import asyncio

client = OpenAIChatCompletionClient(
    model="{{selectedModel.id}}",
    base_url="https://api.doubleword.ai/v1",
    api_key="{{apiKey}}",
)

async def main():
    messages = [Message(role="user", contents=["Say hello."])]
    response = await client.get_response(messages)
    for content in response.messages[0].contents:
        if hasattr(content, "text") and content.text:
            print(content.text)

asyncio.run(main())

Batch pricing with Autobatcher

For background tasks where latency is not critical, use Autobatcher to transparently route requests through the Batch API at reduced cost:

pip install agent-framework-openai agent-framework-core autobatcher

from autobatcher import BatchOpenAI
from agent_framework import Message
from agent_framework_openai import OpenAIChatCompletionClient
import asyncio

batch_client = BatchOpenAI(
    api_key="{{apiKey}}",
    base_url="https://api.doubleword.ai/v1",
)

client = OpenAIChatCompletionClient(
    model="{{selectedModel.id}}",
    async_client=batch_client,
)

async def main():
    messages = [Message(role="user", contents=["Say hello."])]
    response = await client.get_response(messages)
    for content in response.messages[0].contents:
        if hasattr(content, "text") and content.text:
            print(content.text)
    await batch_client.close()

asyncio.run(main())

BatchOpenAI is a drop-in AsyncOpenAI subclass that collects requests and submits them as batch jobs automatically, cutting inference costs by up to 90%.

Available clients

The framework provides three client types, all of which accept base_url and api_key:

Client	Endpoint
`OpenAIChatCompletionClient`	`/chat/completions`
`OpenAIChatClient`	`/responses` (Responses API)
`OpenAIEmbeddingClient`	`/embeddings`

The Doubleword API supports all three endpoints.
