  version: "1.0"

paths:
  /format-money:
    get:
      summary: Get some money
      operationId: api.convert_to_money
      parameters:
        - name: value
          in: query
          type: integer
      responses:
        200:
          description: OK
          schema:
            type: string
            format: money
