Arazzo is a new specification developed by the OpenAPI Initiative to facilitate the description and documentation of complex API workflows involving multiple operations or endpoints. Named after the Italian word for "tapestry," Arazzo aims to weave sequences of API calls into cohesive workflows, providing a clear framework for delivering specific outcomes. Developed by a special interest group within the OAI, Arazzo caters to diverse use cases, including testing, documentation, and AI, by offering a declarative format that connects operations through inputs and outputs. The specification allows for the creation of structured documentation and guides that overcome the limitations of traditional API reference documentation, which often lacks clarity on the necessary sequence of operations. Similar to OpenAPI, Arazzo uses JSON Schema for input definition and introduces a new referencing mechanism to maintain compatibility with existing standards while offering enhanced functionality. Tooling vendors are already working on supporting Arazzo, with early prototypes like the arazzo-runner available to test and build workflows before more comprehensive tools are developed.
