What Is Postman AI Agent Builder?

Postman AI Agent Builder is a no-code and low code platform that helps users build intelligent agents by combining APIs, large language models (LLMs), and visual workflows. At Add AI Directory, we feature Postman AI Agent Builder for its smooth integration of LLMs like OpenAI, Claude, and Gemini into Postman's trusted API infrastructure.

Using Postman Flows, users can visually design, test, and deploy AI-powered automations without writing boilerplate code.
