After preparing your API Key and selecting a model, you can start making API calls. Here are examples using curl, Python SDK, and Java SDK:

When using GLM Coding Plan, please follow the tutorial to configure your dedicated endpoint.

cURL

Official Java SDK
OpenAI Python SDK
OpenAI NodeJs SDK
OpenAI Java SDK

curl -X POST "https://api.z.ai/api/paas/v4/chat/completions" \
-H "Content-Type: application/json" \
-H "Accept-Language: en-US,en" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{
    "model": "glm-5.2",
    "messages": [
        {
            "role": "system",
            "content": "You are a helpful AI assistant."
        },
        {
            "role": "user",
            "content": "Hello, please introduce yourself."
        }
    ]
}'

Install SDK

# Install latest version
pip install zai-sdk

# Or specify version
pip install zai-sdk==0.2.3

Verify Installation

import zai
print(zai.__version__)

Usage Example

from zai import ZaiClient

# Initialize client
client = ZaiClient(api_key="YOUR_API_KEY")

# Create chat completion request
response = client.chat.completions.create(
    model="glm-5.2",
    messages=[
        {
            "role": "system",
            "content": "You are a helpful AI assistant."
        },
        {
            "role": "user",
            "content": "Hello, please introduce yourself."
        }
    ]
)

# Get response
print(response.choices[0].message.content)
