Buy a license by duration

按时长购买授权卡

You receive a license key instantly after payment. The timer starts only on first activation; one device at a time, and you can re-activate on a new device to transfer it.

付款后立即获得卡密（授权卡）。卡密首次激活才开始计时，同一时间绑定一台设备，换机可在新机激活接管。

Before buying: OpusChat works with Cursor's official API path, and usage/billing is real. For heavy sessions, prepare a dedicated Cursor Pro account that you do not rely on for normal daily work. If you do not have one, support can provide a dedicated Pro account for $15/month. 购买前准备：OpusChat 调用的是 Cursor 官方 API 路径，使用与计费都是真实发生的。重度使用时，建议准备一个后续不再依赖的专用 Cursor Pro 账号，不要用自己日常还要继续使用的主账号。如果没有，可联系支持提供专用 Pro 账号，价格为 $15/月。
