Provider: Azure OpenAI

Use Respan Gateway to call Azure OpenAI deployments (gpt-5.5, gpt-5, gpt-5-mini, o3, and the rest) while keeping unified observability (logs, cost, latency, reliability) in Respan.

Quick setup

Send your first request

Pick the integration that matches your stack. The base URL is https://api.respan.ai/api and the only key needed is your RESPAN_API_KEY. Use the azure/ prefix plus your deployment name (or any Azure-compatible model ID) as the model.

1
from openai import OpenAI
2
3
client = OpenAI(
4
    api_key="YOUR_RESPAN_API_KEY",
5
    base_url="https://api.respan.ai/api",
6
)
7
8
response = client.chat.completions.create(
9
    model="azure/gpt-5.5",
10
    messages=[{"role": "user", "content": "Hello, Azure OpenAI!"}],
11
)
12
print(response.choices[0].message.content)

More integrations

Azure OpenAI models work with every Respan gateway integration:

• OpenAI SDK
• OpenAI Agents SDK
• LangChain
• LangGraph
• LlamaIndex
• Pydantic AI
• Respan native (OTel)

Switch models

Change the model parameter to call any supported model through the same client. Use the azure/ prefix plus your Azure deployment name (or model ID) to disambiguate when routing across providers. Browse the full list on the Models page.

1
client.chat.completions.create(model="azure/gpt-5.5", messages=messages)
2
client.chat.completions.create(model="azure/gpt-5-mini", messages=messages)
3
client.chat.completions.create(model="azure/o3", messages=messages)
4
client.chat.completions.create(model="openai/gpt-5.5", messages=messages)
5
client.chat.completions.create(model="anthropic/claude-sonnet-4-5-20250929", messages=messages)

Use your own Azure OpenAI key (BYOK)

Credits are the default path. If you’d rather bill Azure directly, attach your own Azure OpenAI credentials.

Override credentials per model (Optional)

Use credential_override when one model on a request should use a different Azure resource than the default.

Log without proxying (Optional)

Already calling Azure OpenAI directly? Send logs to Respan asynchronously to track cost, latency, and performance for those external calls.

1
import requests
2
3
requests.post(
4
    "https://api.respan.ai/api/request-logs/create/",
5
    headers={
6
        "Authorization": "Bearer YOUR_RESPAN_API_KEY",
7
        "Content-Type": "application/json",
8
    },
9
    json={
10
        "model": "azure/gpt-5.5",
11
        "prompt_messages": [{"role": "user", "content": "Hello, how are you?"}],
12
        "completion_message": {"role": "assistant", "content": "Hello from Azure OpenAI through Respan."},
13
        "cost": 0.001,
14
        "generation_time": 1.2,
15
        "customer_params": {"customer_identifier": "user_123"},

    },

)
