Migrate from the OpenAI API to TokenRex

Steps

• Create a TokenRex API key and add wallet balance.
• Change the base URL to https://tokenrex.ai/api/public.
• Replace your OpenAI key with the TokenRex key.
• Keep your model IDs, or try Claude and Gemini by changing only the model ID.

What to check after switching

• Run your existing test prompts and compare replies.
• Check the usage field in responses to confirm token counts and costs.
• Short model IDs are used on TokenRex, for example gpt-6-sol rather than openai/gpt-6-sol.

Example

from openai import OpenAI

client = OpenAI(api_key="YOUR_TOKENREX_KEY", base_url="https://tokenrex.ai/api/public")

resp = client.chat.completions.create(
    model="gpt-6-astra",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)

Questions

Can I switch back?

Yes. Nothing is locked in: change the base URL and key back and your code keeps working.
