Quickstart
Call any model with the OpenAI SDK.
Create an API key in the customer console, set the hosted base URL, and switch between gpt-5.5, claude-opus-4-7, and deepseek-chat by changing one string.
Recharge
Keep prepaid balance available before running production traffic.
Create token
Generate an API key and store it in your server environment.
Call API
Use api.modelbridgeapi.com/v1 as the base URL.
Python
OpenAI-compatible client
Replace the key with the token created in the console.
# Install the official OpenAI SDK pip install openai from openai import OpenAI client = OpenAI( api_key="YOUR_MODELBRIDGE_API_KEY", base_url="https://api.modelbridgeapi.com/v1" ) # Switch by model name — same SDK, same base URL response = client.chat.completions.create( model="gpt-5.5", # or "claude-opus-4-7", "deepseek-chat" messages=[{"role": "user", "content": "Say hello"}] ) print(response.choices[0].message.content)
REST
Chat completions
The hosted API follows the OpenAI-compatible /v1 shape for supported routes.
curl https://api.modelbridgeapi.com/v1/chat/completions \ -H "Authorization: Bearer YOUR_MODELBRIDGE_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "gpt-5.5", "messages": [{"role":"user","content":"Hello"}] }'
Route policy
Use compliant upstream APIs.
ModelBridge is not designed around account pools, subscription resale, browser reverse engineering, or unlimited-access claims. Every model is backed by an official API or verified partner channel.
