APIs.json
APIs.json is an open-source machine-readable format for indexing the surface area of an API project — its operations, OpenAPI files, JSON Schema, JSON-LD contexts, documentation, pricing, status page, and maintainer contacts. It functions as a sitemap.xml for APIs and is the structural backbone of every repository in the API Evangelist network. The current stable revision is 0.20 with a 0.21 draft in flight.
