大家开发完 OpenAI 的产品后经常需要关注费用情况，也有很多网站支持输入 api_key 查询余额。
但是，你真的敢用么？

这里教大家自己用 python 写一段查询 openai key 的代码，如下：

import datetime# 用您的 API 密钥替换以下字符串
import requests
import settingssubscription_url = "https://api.openai.com/v1/dashboard/billing/subscription"def getUsage(apikey):headers = {"Authorization": "Bearer " + apikey,"Content-Type": "application/json"}subscription_response = requests.get(subscription_url, headers=headers)if subscription_response.status_code == 200:data = subscription_response.json()total = data.get("hard_limit_usd")else:return subscription_response.text# start_date设置为今天日期前99天start_date = (datetime.datetime.now() - datetime.timedelta(days=99)).strftime("%Y-%m-%d")# end_date设置为今天日期+1end_date = (datetime.datetime.now() + datetime.timedelta(days=1)).strftime("%Y-%m-%d")billing_url = f"https://api.openai.com/v1/dashboard/billing/usage?start_date={start_date}&end_date={end_date}"billing_response = requests.get(billing_url, headers=headers)if billing_response.status_code == 200:data = billing_response.json()total_usage = data.get("total_usage") / 100daily_costs = data.get("daily_costs")days = min(5, len(daily_costs))recent = f"最近{days}天使用情况  \n"for i in range(days):cur = daily_costs[-i-1]date = datetime.datetime.fromtimestamp(cur.get("timestamp")).strftime("%Y-%m-%d")line_items = cur.get("line_items")cost = 0for item in line_items:cost += item.get("cost")recent += f"\t{date}\t{cost / 100} \n"else:return billing_response.textreturn f"\n总额:\t{total:.4f}  \n" \f"已用:\t{total_usage:.4f}  \n" \f"剩余:\t{total-total_usage:.4f}  \n" \f"\n"+recentprint(getUsage(settings.Config.chat_gpt_key))
