Example mentioned at [Calling Deployments via HTTP and Python — Ray v1.9.0](https://docs.ray.io/en/latest/serve/http-servehandle.html#fastapi-http-deployments), does not seems to be working for me.

Here is how I am running.

```auto
#main.py
import ray

from fastapi import FastAPI
from ray import serve

app = FastAPI()
ray.init(address="auto", namespace="summarizer")
serve.start(detached=True)

@app.get("/")
def f():
    return "Hello from the root!"

@serve.deployment(route_prefix="/api1")
@serve.ingress(app)
class FastAPIWrapper1:
    @app.get("/subpath")
    def method(self):
        return "Hello 1!"

@serve.deployment(route_prefix="/api2")
@serve.ingress(app)
class FastAPIWrapper2:
    @app.get("/subpath")
    def method(self):
        return "Hello 2!"

FastAPIWrapper1.deploy()
FastAPIWrapper2.deploy()

```

I am starting ray with `ray start --head`

Here is the output from post deployment

```auto

```

After deployment, here is successful `curl` calls

```auto
❯ curl http://127.0.0.1:8000/api1/subpath
"Hello 1!"%
❯ curl http://127.0.0.1:8000/api2/subpath
"Hello 2!"%

```

But when I try to run `curl` to root, its failing.

```auto
❯ curl http://127.0.0.1:8000/
Path '/' not found. Please ping http://.../-/routes for route table.%

```

I am trying to assess if any endpoints that are available via FASTapi would still be available or not. Please let me know if I am missing something here.

Got it, path `http://127.0.0.1:8000/` is not directly accessible. Due to ingress, its under the route where it is part of.

Changed path as below

```auto
@app.get("/fastapi")
def f():
    return "Hello from the root!"

```

Now I can call

```auto
❯ curl http://127.0.0.1:8000/api1/fastapi
"Hello from the root!"

```
