Prompt API is a curated API marketplace with high scalability and security for developers. It differentiates from large and uncurated API marketplaces like rapid API by its selection process and hosting options. Prompt API handpicks high-quality API applications from developers and hosts them in its servers for high availability and scalability (unlike many other API marketplaces). It also provides a single SDK to connect all APIs in the marketplace to solve vendor lock-in problem. Our customers can freely change vendors without the hastle of manuel development. Moreover, Prompt API provides full featured “headless app backends” for building up new white-labeled products and all APIs have a rate limited free plan to try out.
