from fastapi.security import OAuth2PasswordBearer

app = JustAPIApp()
oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")

async def get_current_user(token: str = Security(oauth2_scheme)):
    # Decode JWT and return user
    user = decode_token(token)
    if user is None:
        raise HTTPException(status_code=401, detail="Invalid token")
    return user

@app.get("/users/me")
