By classifying operations as atomic, workflow, asynchronous, introspective, discovery, reactive, bulk, or simulated, you create a predictable map that helps machines navigate APIs safely.—The Taxonomy of API Operations

Inferred API operation categories. This is the distribution of API operation categories after analyzing more than 50k OpenAPI documents from public GitHub repositories. I inferred a taxonomy by comparing the morphology of each API operation with a set of pre-established heuristics.
