/// note | Technical Details

You could also use `from starlette import status`.

**FastAPI** provides the same `starlette.status` as `fastapi.status` just as a convenience for you, the developer. But it comes directly from Starlette.

///

## Changing the default { #changing-the-default }

# Additional Status Codes { #additional-status-codes }

By default, **FastAPI** will return the responses using a `JSONResponse`, putting the content you return from your *path operation* inside of that `JSONResponse`.

It will use the default status code or the one you set in your *path operation*.

## Additional status codes { #additional-status-codes_1 }

# Response - Change Status Code { #response-change-status-code }

You probably read before that you can set a default [Response Status Code](../tutorial/response-status-code.md){.internal-link target=_blank}.

But in some cases you need to return a different status code than the default.

## Use case { #use-case }

For example, imagine that you want to return an HTTP status code of "OK" `200` by default.

        // Enum instances are singletons
        CrawlerStatus status1 = CrawlerStatus.INITIALIZING;
        CrawlerStatus status2 = CrawlerStatus.INITIALIZING;

        // Should be the same instance
        assertSame(status1, status2);
        assertTrue(status1 == status2);

        // valueOf should return the same instance
        CrawlerStatus status3 = CrawlerStatus.valueOf("INITIALIZING");

		switch bktStatus {
		case ResyncCompleted:
			st.BucketStatuses[o.bucket] = ResyncCompleted
			st.Status = siteResyncStatus(st.Status, st.BucketStatuses)
			st.LastUpdate = UTCNow()
			sm.resyncStatus[o.resyncID] = st
		case ResyncFailed:
			st.BucketStatuses[o.bucket] = ResyncFailed
			st.Status = siteResyncStatus(st.Status, st.BucketStatuses)
			st.LastUpdate = UTCNow()
			sm.resyncStatus[o.resyncID] = st
		}
	}
}

  status->status = c.construction_status();
  if (!status->status.ok()) return;

  if (op_reg_data->shape_inference_fn == nullptr) {
    status->status =
        InvalidArgument("No shape inference function exists for op '",
                        node_def.op(), "', did you forget to define it?");
    return;
  }

  status->status = c.Run(op_reg_data->shape_inference_fn);
