Essevin ResourcesChoose How to Use Essevin
Choose one of two paths: connect a coding tool with CC Switch, or generate product images in Creative Studio.
The first time you use Essevin, just choose one path — see the table below for how they differ. For other integration methods (SDKs, editors, third-party clients), see the docs home.
| Path | Best for | API key | Installation |
|---|---|---|---|
| 1 · Coding tools | Write code in Codex App, Codex CLI, or Claude Code | Required; the group depends on the tool | CC Switch and the target client |
| 2 · Creative Studio | Generate product images in the browser | Not required | Not required |
Path 1: use Codex or Claude Code (3 steps)
This path needs an API key from the correct plan group. CC Switch imports and switches provider settings, but it does not install the target client.
Prepare the target client
For Codex CLI or Claude Code, install the LTS version of Node.js from nodejs.org. Skip Node.js if Codex App is already installed.
Codex CLI: npm install -g @openai/codex
Claude Code: npm install -g @anthropic-ai/claude-code
Install only the client you plan to use. An installed Codex App does not require a second CLI installation.
Create a key from the correct plan group
Open the console's API Keys page and click Create Key. Choose the Claude group for Claude Code; choose Codex Plus or Codex Pro for Codex. Never paste a complete key into chat, a support ticket, or a screenshot.
Import into CC Switch and enable
Open the key row's More menu and select Import CCS. Choose Codex CLI for Codex App or Codex CLI; choose Claude Code for Claude Code. Confirm the import when the browser opens CC Switch, select the matching client tab, and choose Enable. See the CC Switch guide for every click. Restart Codex App or open a new CLI terminal after switching.
Path 2: create product images in Creative Studio
After you sign in to the console, open Creative Studio directly. Choose Image, enter a prompt, and set the model, aspect ratio, or size. This path does not require an API key.
