REST API documentation and publishing using the Open API v3.0 spec

My REST API documentation experience is with material covered by NDA’s. Here are two versions of a self-created API docs sample utilizing the Open API spec:

1) Stoplight, with a more-readable, contemporary 3-panel design.

2) Swaggerhub, an older interface design with a working Try-it feature where the reader can make a live API call.

• This API example brings an under-documented public API up to current standards for API docs.
• I implemented three endpoints in the OpenAPI spec from the API of 511.org, a San Francisco Bay Area transit organization.
• I created an abbreviated developer guide or quick start with code samples, procedural instructions and some partial reference content.

Note: This demo was created by me without the assistance of any subject matter experts at 511.org.
