Example Code

@app.get("/", dependencies=[Depends(RateLimiter(times=2, seconds=5))])
async def index():
    return {"msg": "Hello World"}

Description

There is no official way to add ratelimit in path operation functions , it would be good if we could limit requests to a specific rate , for example: a client can only request to "/" path 3 times in 60 seconds.
NOTE: Im aware of libraries made for handling this , but they are not trustable and useful enough.

Wanted Solution

i would like a dependency class to handle ratelimits , Both for HTTP And WEBSOCKET Requests

Wanted Code

@app.get("/", dependencies=[Depends(RateLimiter(times=2, seconds=5))])
async def index():
    return {"msg": "Hello World"}

What isn't trustable about them?
They're both literally open-source. You can go ahead and read the code line-by-line if you wanted to to make sure they aren't doing anything nefarious. Which I doubt they are.

You managed to find a solution which support websockets

I think this features should be built into FastAPI.

Dude, did you go through the documentation of fastapi-limiter? 'cause it does support websocket.
