APIs.json

APIs.json is a machine-readable metadata format used to describe APIs (Application Programming Interfaces) and their associated resources. It acts as a discovery format similar to how robots.txt helps search engines discover web pages. The goal of APIs.json is to simplify the process of finding, cataloging, and integrating APIs by providing a standardized way to document the follow details.

  • Technical - With APIs.json you can index OpenAPI, but also Postman or Bruno collections, and any other machine-readable artifact that defines the surface area of individual APIs.
  • Business - With APIs.json you can index the aspects of API operations that business stakeholders will care most, like discovery, onboarding, billing, and areas more aligned with business.
  • Common - Using APIs.json, you can define the technical and business details of each individual API, but also the shared properties available across many APIs in a standardized way.

APIs.json can provide an index for an entire API portal, or a single API in a GitHub repository. APIs.json can be indexed to provide search and discovery for APIs, but also a machine-readable artifact that can be used to govern the operations surrounding APIs. APIs.json is designed to do for API operations, what OpenAPI has done for APIs.

Providers that carry APIs.json 2

These providers' own APIs.json profiles carry APIs.json as a tag — the provider's statement that the standard is part of what it does. APIs.io has not verified the implementation on this page; the de facto profiles on this site are where that measurement exists. Ordered by Kin Score.
