# Migrate from OpenAI or OpenRouter

> Point an existing OpenAI-compatible integration at RedPill: a new base URL, a new key, and provider-prefixed model ids.

RedPill is OpenAI-compatible, so a migration is a base URL and a key. Model ids carry a provider
prefix, the same format OpenRouter uses.

  ```python Python theme={null}
  import os
  from openai import OpenAI

  client = OpenAI(
      api_key=os.environ["REDPILL_AI_API_KEY"],
      base_url="https://api.redpill.ai/v1",
  )
  response = client.chat.completions.create(
      model="openai/gpt-5",
      messages=[{"role": "user", "content": "Hello"}],
  )
  ```

  ```javascript JavaScript theme={null}
  import OpenAI from "openai";

  const client = new OpenAI({
    apiKey: process.env.REDPILL_AI_API_KEY,
    baseURL: "https://api.redpill.ai/v1",
  });
  ```

Streaming, function calling, vision, and error shapes are unchanged. What RedPill adds: every
response carries an `x-receipt-id` you can [verify](/guides/verify-a-response), and confidential
(`is_tee`) models run on a verified upstream enclave. See [Models](/get-started/models).
