Cursor is a VS Code-based AI coding IDE with built-in AI chat, code completion, and code generation.

​
Setup Steps

1

Open Cursor Settings

Press Cmd/Ctrl + Shift + J in Cursor, or go to File → Preferences → Cursor Settings.
2

Go to the Models Tab

In the settings panel, click the Models tab on the left. Scroll down to the OpenAI API Key section.
3

Enter Your API Credentials

  • OpenAI API Key: Enter your ePhone AI API key (starts with sk-)
  • Override OpenAI Base URL: Enter https://api.ephone.ai/v1
Click Verify to confirm the connection.
4

Add or Select Models

In the Models list, type any model name supported by the platform — for example gpt-4o, deepseek-r1, or claude-opus-4-5-20251101.

​
Notes

Cursor’s third-party API mode currently only supports the Chat feature. Cursor Tab (inline completions) and Agent mode require an official Cursor subscription.
  • Enter the full model name directly, e.g. claude-opus-4-5-20251101
  • For the best stability, set your token’s provider to Official or Enterprise in the ePhone AI console
  • If a model appears unavailable, verify that it’s included in your token’s allowed model list
