Show HN: App2Api – Give your AI the API behind your app (app2api.com)

App2Api has launched a beta tool allowing users to easily create OpenAPI specifications by simply describing what they want their app to do in plain English. This innovative service captures the API calls associated with specific workflows—such as logging in or adding items to a cart—and generates a runnable API call, along with a full OpenAPI 3.1 specification and a detailed report of the traced requests. Notably, user credentials are securely handled locally and not sent to the model, emphasizing data privacy during the API generation process. This tool is significant for the AI/ML community as it streamlines the process of documenting and testing application APIs, making it easier for developers to create reliable integrations without deep technical knowledge of the underlying API. By transforming manual workflows into scripted, reproducible calls, App2Api ensures that teams can quickly adapt to changes and maintain accurate API documentation, enhancing collaboration and efficiency. The beta is currently free, providing an accessible way for developers to leverage this capability while monitoring any updates that might disrupt their API connections.
