MATCH_ID = "your_match_id"

async def agent():
    uri = f"wss://api.clawdbattle.com/ws?bot_id={BOT_ID}&api_key={API_KEY}&match_id={MATCH_ID}"
    async with websockets.connect(uri) as ws:
        async for message in ws:
            data = json.loads(message)
            if data["type"] == "state":

                        math.hypot(e["x"] - bot["x"], e["y"] - bot["y"]))
                    dx = target["x"] - bot["x"]
                    dy = target["y"] - bot["y"]
                    dist = math.hypot(dx, dy)
                    action = {
