Watsonx (gateway)

Route Watsonx calls through the Respan gateway with an OpenAI-compatible client. This setup uses your RESPAN_API_KEY; your application does not need to manage IBM Watsonx credentials directly.

Use a Watsonx model ID from your Respan model list. If your workspace uses a custom Watsonx deployment, use the model name shown in the platform.

Setup

pip install openai

export RESPAN_API_KEY="YOUR_RESPAN_API_KEY"

import os
from openai import OpenAI
client = OpenAI(
    api_key=os.environ["RESPAN_API_KEY"],
    base_url="https://api.respan.ai/api",
)
response = client.chat.completions.create(
    model="YOUR_WATSONX_MODEL_ID",
    messages=[{"role": "user", "content": "Say hello in three languages."}],
)
print(response.choices[0].message.content)

Switch models

Change the model parameter to use 1000+ models from different providers through the same gateway.

response = client.chat.completions.create(model="YOUR_WATSONX_MODEL_ID", messages=messages)
response = client.chat.completions.create(model="openai/gpt-6-sol", messages=messages)
response = client.chat.completions.create(model="anthropic/claude-opus-5-5", messages=messages)
