Migrate from OpenRouter to TokenRex

Steps

• Create a TokenRex API key and top up in rupees.
• Change the base URL from OpenRouter's to https://tokenrex.ai/api/public.
• Remove the provider prefix from model IDs (openai/gpt-6-sol becomes gpt-6-sol).
• Remove OpenRouter-only headers; they are not needed.

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-sol",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)

Questions

Do old prefixed model IDs still work?

Yes, prefixed IDs are still accepted for compatibility, but short IDs are recommended.

Can I switch back?

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