OpenAPI.
A standard file that describes every route of an API: its paths, inputs and answers. An agent can read it to learn the API without reading the docs.
Also called OpenAPI spec, Swagger.
In our drives.
Each drive records whether the product publishes one, and whether the API answered the way its docs say.
How many sites publish one, month by month
