Provider: Moonshot AI

Use Respan Gateway to call Moonshot AI models (kimi-k2, moonshot-v1-128k, and the rest of the Kimi family) 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.

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="moonshot/kimi-k2",
10
    messages=[{"role": "user", "content": "Hello, Kimi!"}],
11
)
12
print(response.choices[0].message.content)

More integrations

Moonshot 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 moonshot/ prefix to disambiguate when routing across providers. Browse the full list on the Models page.

1
client.chat.completions.create(model="moonshot/kimi-k2", messages=messages)
2
client.chat.completions.create(model="moonshot/moonshot-v1-128k", messages=messages)
3
client.chat.completions.create(model="moonshot/moonshot-v1-32k", 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", messages=messages)

Use your own Moonshot AI key (BYOK)

Credits are the default path. If you’d rather bill Moonshot directly, attach your own provider key.

Override credentials per model (Optional)

Use credential_override when one model on a request should use a different Moonshot key than the default.

1
{
2
  "customer_credentials": {
3
    "moonshot": { "api_key": "YOUR_MOONSHOT_API_KEY" }
4
  },
5
  "credential_override": {
6
    "moonshot/kimi-k2": { "api_key": "ANOTHER_MOONSHOT_API_KEY" }
7
  }
8
}

Log without proxying (Optional)

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