# How to integrate RouterLink in a self-hosted environment

**Step1:** Go to the model details page and find the Integration Guide field.

**Step2: Click the "Copy" button** on the right under Integration Guide to copy the Endpoint and Python code (This operation uses GPT-5.2 as an example).

**Step3:** Open a program on your computer that can run Python code (e.g., Cursor, VS Code, PyCharm). This example uses PyCharm.

**Step4:** Paste the **copied Endpoint** and **Python code** into PyCharm.

**Step5:** Replace the content of the field api\_key="\<ROUTER\_LINK\_API\_KEY>" with the previously generated API Key, as shown in the image below.

**Note:** This operation is relatively simple and suitable for users with Python development experience. It is mainly used to quickly verify whether the RouterLink API is configured successfully, or to integrate it into existing backend services, scripts, or automated tasks.
