format
binary - any sequence of octets
Base type: string
.
The binary
format represents any sequence of octets. This format entry is to ensure future versions of OpenAPI maintain compatibility with OpenAPI 3.0.x.
Remarks
In OpenAPI 3.1, instead set the media type appropriately and do not use a schema property. Note that only complete HTTP message bodies or complete parts in a multipart media type can accommodate binary data. JSON strings and URL path components cannot.
