openapi-directory

Directory of API definitions in OpenAPI(fka Swagger) 2.0 and 3.x formats.
API access to collection: Go! - We also have RSS feeds for added and updated APIs.

Our goal is to create the most comprehensive, standards-compliant and up-to-date directory of machine-readable API definitions, with the following principles:

Open source, community driven project.
Only publicly available APIs (free or paid).
Anyone can add or change an API, not only API owners.
All data can be accessed through a REST API.

If you want to reference this project and you need an icon or even a banner, check our branding guide.

The project was started by Ivan Goncharov of APIs.guru, it is now maintained by Mike Ralphson of Mermade Software. Check out our other OpenAPI-related projects.

APIs.guru provide services and consultancy around the GraphQL and OpenAPI specifications and APIs in general. You can contact us at founders@apis.guru / mike.ralphson@gmail.com

The OpenAPI Directory is sponsored by Speakeasy - Your API: Enterprise ready in a click.

What does APIs.guru do?

Filter out private and non-reliable APIs
Convert non-OpenAPI formats into OpenAPI 3.x
Fix mistakes, ~80% of definitions have some
Add additional data, like: logo, categories, …
Update definitions on at least a weekly basis

API definition acceptance criteria

Public - anyone can access it as long as they follow some clearly defined steps (subscribe, pay fees, etc.).
Persistent - API is made with long-lived goal, and not for a particular event (conference, hackathon, etc.).
Useful - API should provide useful functionality not only for its owner.

Update procedure

All definitions are automatically updated from their original source. You can see this in the x-origin property within each openapi.yaml or swagger.yaml file. We run our update script at least weekly and automatically revalidate before committing. If you see some APIs are not updated for more than 2 weeks please open an issue.

@seriousme kindly runs a backup validation process based on the official OpenAPI-Specification JSON Schemas here.

Own-Label API Directory
