QuarkIQL is an AI tool for generative testing of computer vision APIs. It allows users to create custom images and requests with just a few clicks. The tool offers powerful image diffusion models, making it easy to generate test images based on user prompts. Quark also simplifies the process of making requests by supporting GET, POST, and other methods. It keeps a log of queries to enable running more experiments without starting from scratch. With QuarkIQL, users can streamline their image API testing workflow and track their testing history. The tool is designed to assist software engineers and developers in testing computer vision APIs effectively. The team behind QuarkIQL consists of experienced software engineers with backgrounds in Operations Research and Mechanical Engineering. Users can sign up to access the image API testing workflow and follow a simple three-step process to generate test images, modify request parameters, and send requests to the API endpoint being tested.
