| Free tier | Free: 50 GB of 专业空间 (own uploads, no deduplication) plus 2 TB of 标准空间 (files saved from other people's shares, deduplicated) for accounts registered before 2026-09-24 14:30. New accounts get 50 GB plus 50 GB until real-name verification, then 2 TB standard unit TiB; metered on stored-bytes; the quota regime changed twice in twelve months, so the date qualifier is part of the fact |
|---|---|
| Price | none stated |
| Limits | |
| Binding | per-ip-shaping The capacity is real and large, so the quota is not what stops a plan. |
| Identity | country-phone the login page offers app or WeChat QR login, or a phone-or-email password login, but the signup path terminates at +86 SMS. A 2026 guide states 'mainland +86 number only, email sign-up stops at phone binding' |
| Egress | Uploads and downloads are stated as unlimited in speed (上传下载不限速) with CDN direct links, but a free account is capped at 10 GB of extraction traffic per month across all clients, quoted at CNY 0.05/GB beyond. Since 2025-11-26 every share download requires a login free allowance: 10 GB per month price per tb: CNY 0.05/GB beyond the allowance |
| Per-object cap | 10 GB per file in 标准空间. Files over 10 GB, multi-volume archives, direct-link and image-host output are billed to the 50 GB 专业空间 instead (10000000000 bytes) |
| Retention | Share links expire; live keys returned 5104 分享已过期. Account retention is not published |
| Interface | rest, webdav |
| Tooling | an official Open Platform at open-api.123pan.com with client id and key and a refresh-token flow; the OpenList '123 Open' driver; WebDAV at webdav.123pan.cn/webdav with app passwords, up to ten per account; the Python client ChenyangGao/p123client |
| Composes with | The one interesting shape is the deduplicated 标准空间: saving an already-present blob costs no quota, so a shared corpus can be mirrored into many accounts at no storage cost |
| Reliability | Two independent failure modes seen on the same day: 5104 分享已过期 on most public keys, and 5112 分享方提取流量包不足 on live ones. The sharer's traffic pack is the binding constraint, so a valid share with an exhausted pack is unusable by anyone including a logged-in user. The quota regime changed in 2025-11 and again in 2026-09 and the operator blames bulk registration |
| Notes | The site's own headline still advertises 免费用户高达2TB容量, VIP享20TB容量, SVIP享100TB容量, which is the offer before the 2026-09 split. |
