I am attempting to create an OAS schema for an empty JSON body:

```auto
{ }

```

I am trying to get the documentation to show an empty JSON body, and have that autogenerated.

The API defines this as a POST (yes, it ought to be a GET, the design of the API is in some respects sub-optimal) request, and expects the open/close bracket, and nothing else. I’ve tried

```auto
  …
  content:
    application/json: { }
  …

```

but that doesn’t work (it just shows nothing in the request body), and everything else I’ve tried is invalid. Would appreciate any assistance on this. I have not been able to find any examples or even similar questions (maybe I’m looking in the wrong place?).

Any assistance would be greatly appreciated!

Solved.

```auto
      requestBody:
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/EmptyBody'

# # # # # # 

     EmptyBody:
          type: object
          nullable: true

```

How can I give empty JSON as an “example” at components/schemas of swagger JSON?

I tried this

```auto
"components": { "schemas": { "APIname":{ "type": "object", "properties": {}, "example": {} }}

```

But this example is not executed when I use schemathesis to run test cases.
