- An open spec for describing REST APIs [ github ]
- Tools for auto-generating
- Documentation
- Code for your API
- Donated to the OpenAPI initiative and renamed OpenAPI in 2015

- Documentation
- An exploration interface for your API
- Apiary and API Blueprint
- Write the API description in a DSL within markdown
