   [
   \Zfegg\ContentValidation\ContentValidationMiddleware::class,
    function (\Psr\Http\Message\ServerRequestInterface $request) {
        $data = $request->getParsedBody(); // Get valid data.
    }
], 'api.users.create')
->setOptions(['schema' => 'path-to-json-schema.json'])
//->setOptions([  
//   // or set json-schema object. 
//  'schema' => (object) [

        "table": "foo",      // Table name
        "field": "key",      // Field name
        "exists": true       // Check record exists or not exists. Default: false
      }
  }

• DoctrineRecordExistsFilter: Use doctrine/orm to check record exists. The json-schema $filters config:
