定价与积分 / Pricing

一次性付款，不是订阅，不自动续费或充值；购买的积分不过期。付款由 Waffo（Waffo.com Limited，经销商及记录商户）处理，税费以收银台显示为准。
One-time payments, not subscriptions; nothing renews or tops up automatically and purchased credits do not expire. Payments are processed by Waffo (Waffo.com Limited, reseller and merchant of record); taxes are shown at checkout.

积分包 / Credit packs

登录后在账户菜单的「购买积分」中购买，付款完成后积分自动到账。注册本身不收费，新账号默认没有使用额度。
Buy from "Buy credits" in the account menu after signing in; credits are added automatically once payment completes. Registration is free and new accounts start with no credits.

如何扣减 / How credits are used

1 积分相当于 1 美元的 OpenRouter 实际模型费用。论文写作、编辑、文献处理等使用模型的操作按实际模型费用扣减，具体消耗因任务、输入输出长度和模型而异。系统可能先预留积分，任务结算以实际费用为准；一次任务所需积分并非固定值。
One credit covers US$1 of actual model costs reported by OpenRouter. Writing, editing and other model-powered tasks use credits according to their actual costs. Usage varies by model, task and input/output length; an estimated amount may be reserved before settlement.

实验加购 / Experiment add-on

实验功能预计不另收固定加购费；实验及结果回填所产生的实际模型费用，按同样规则从积分余额扣减。实验任务所需积分因任务而异。检索、邮件及沙箱费用目前未按用户单独计量；若未来收费方式变化，我们会在购买前说明。
No separate fixed experiment fee is planned. Experiment and results backfill model costs use credits at the same rate. Search, email and sandbox costs are not currently metered separately to users; future changes will be disclosed before purchase.

退款与联系 / Refunds and support
