Let's continue with the same file structure as before:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

Let's say that now the file `main.py` with your **FastAPI** app has some other **path operations**.

It has a `GET` operation that could return an error.

It has a `POST` operation that could return several errors.

Both *path operations* require an `X-Token` header.

## Client and SDK Generators - Sponsor

There are also some **company-backed** Client and SDK generators based on OpenAPI (FastAPI), in some cases they can offer you **additional features** on top of high-quality generated SDKs/clients.

		`; export CGO_ENABLED=0` +
		`; export GOPROXY=` + os.Getenv("GOPROXY") +
		`; export GOCACHE="` + deviceRoot + `/gocache"` +
		`; export PATH="` + deviceGoroot + `/bin":$PATH` +
		`; export HOME="` + deviceRoot + `/home"` +
		`; cd "` + deviceCwd + `"` +
		"; '" + deviceBin + "' " + strings.Join(os.Args[2:], " ")
	code, err := adbRun(cmd)
	signal.Reset(syscall.SIGQUIT)
	close(quit)
	return code, err
}
