Its technical architecture is implemented in Node.js, which realizes an end-to-end conversion link from API documents to AI executable operations by providing CLI tools, sample servers and programmatic conversion modules. The project especially targets the scenarios where developers need to frequently test API interfaces and AI engineers build intelligent workflows, providing out-of-the-box Petstore API examples, which dramatically reduces the technical threshold of traditional API access to AI systems.
