GPTZZZ 是面向开发者的独立第三方 AI API 中转与多模型网关，提供 OpenAI 兼容接口和 Claude Messages 接口，帮助应用与编程工具通过对应协议接入模型。服务采用共享预付余额、按实际用量计费的方式，不代表任何模型厂商。 开发者可为所需分组创建 API Key，并在兼容客户端中配置服务地址。每个密钥对应一个分组，同一账户下的余额共用。公开价格页展示模型、分组与调用价格，具体可用范围和扣费以控制台实时信息为准。 网站提供中文接入文档、集成指南、错误码参考和公开服务状态页，便于核对配置、处理调用问题及了解运行状态。服务面向需要在应用和编码流程中调用模型的用户，与 ChatGPT 会员购买分别管理。 现行公开规则支持支付宝充值，单笔人民币十元至两千元，无充值手续费，未使用的余额可申请退款。充值金额是预付余额，不是固定月费；最低充值额也不等于单次调用价格。
