Z.ai API

What is Z.ai API?

Z.ai is the international developer platform for Zhipu AI, offering seamless API access to the highly capable GLM family of foundational models, including GLM-5 and GLM-5.1. Its mission is to inspire Artificial General Intelligence (AGI) to benefit humanity by providing cutting-edge models that excel in reasoning, coding, and complex agentic workflows. The platform serves developers and enterprises by offering standard RESTful APIs alongside specialized GLM Coding Plans tailored for AI coding assistants like Claude Code and Cline. By enabling autonomous task execution over extended periods, Z.ai empowers users to solve complex engineering challenges, build robust tools, and significantly boost their overall productivity.

How to use Z.ai API?

To use Z.ai effectively, users first need to register an account on the platform and generate an API key from the developer dashboard. Developers can integrate the models into custom applications using standard HTTP RESTful APIs or official SDKs available for Python, Java, and Node.js. For software developers utilizing AI coding assistants like Cline or Claude Code, they can subscribe to a GLM Coding Plan, select 'Z AI' as their provider within the tool's settings, and input their API key to leverage advanced model capabilities directly in their IDE.
