API Key Setup

Z Code supports the following ways to access AI services:

• Zhipu GLM Coding Plan, BigModel model resource packages, and prepaid balance
• Zhipu Z.AI
• Native subscriptions for Claude Code / Codex / Gemini
• OpenRouter
• Any AI service compatible with the Anthropic / OpenAI protocol, including self-hosted deployments

API Setup Entry

Method 1: Through Connect

This is best when you want to sign in quickly with an account and start using Z Code immediately. After opening the Z Code desktop app, you will see a welcome dialog.

Click Continue with Z.AI to sign in and enter the workspace. If you do not want to sign in yet, you can also click Skip for now and configure API keys later from the model provider page.

Method 2: Through The Model Selector

After entering Z Code, click the model name inside the chat box to open the model selector dropdown, then click Manage Models at the bottom of the list.

This takes you to the Agents Settings / Models panel, where you can manage all AI service providers.

Custom Providers (Anthropic / OpenAI Compatible)

Z Code supports adding any AI service compatible with the Anthropic / OpenAI protocol as a custom provider.

The experience is more complete in the new release. After you choose a known Base URL or enter a compatible API endpoint, Z Code can automatically detect and load the available model list, so you no longer need to type model names one by one.

Setup Steps

1. Open Agents Settings / Models
2. Click Add Provider at the bottom of the provider list
3. Set a custom name for the provider, such as claude or deepseek
4. Choose or enter a Base URL
5. Enter the API Key
6. Load models automatically after the endpoint is confirmed
7. Turn on the enable switch to start using it

For example, using a GLM-compatible endpoint:

• Set the name to BigModel
• Set the Base URL to https://open.bigmodel.cn/api/anthropic
• Fill in the API key
• Add or adjust models if needed
• Save the provider

Verify The Setup

After configuration, select the target model from the model selector in the chat box and test it directly.
