## 123pan (123云盘)

- `netdisk-pan/123pan-123` | qualifies-with-caveat | evidence reported | binding per-ip-shaping | category consumer-pan
- needs card no, phone yes, ID no, institution no | verified 2026-10-21 (inherited) | stale on 2026-11-05
- url https://www.123pan.com
- 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 | read on: 2026-10-21 | source: [1] | note: the quota regime changed twice in twelve months, so the date qualifier is part of the fact
- 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 | bytes: 10000000000 | source: [2]
- retention: Share links expire; live keys returned 5104 分享已过期. Account retention is not published | source: [1]
- 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 | metered: yes | free allowance: 10 GB per month | price per TB: CNY 0.05/GB beyond the allowance | source: [3]
- identity: country-phone | detail: 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' | country: 86
- interface: rest, webdav
- limits:
  - per-object-cap: 10 GB per file in 标准空间 [2]
  - per-ip-shaping (binding): 10 GB of extraction traffic per month on a free account, all clients [3]
  - write-gated: share downloads require a login since 2025-11-26 [4]
- binding note: The capacity is real and large, so the quota is not what stops a plan.
- 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.
- extras:
  - access_mode: registration-gated
  - anonymous_read: metadata anonymous, bytes refused
  - free_tier_regime_changed: 2025-11 traffic cut, 2026-09 space split
  - openapi_paid_addon: a 开发者权益包 at CNY 20/month from 2026, reported on linux.do
- evidence:
  - [5] 2026-10-21: '老用户免费配额为专业空间 50GB 加标准空间 2TB'; '大于 10GB 的超大文件、分卷压缩文件组，以及直链、图床、视频转码服务产生的文件，也计入专业空间'
  - [3] 2026-10-21: free users '每月累计提取流量上限为合计 10GB', client downloads bill at half, overage CNY 0.05/GB
  - [4] 2026-10-21: '免登录下载100M内小文件的权益取消了，以后要想下载文件，必须登录'

  - probe:https://open-api.123pan.com/api/v1/user/info 2026-10-21: 200 {"code":401,"message":"token is expired"}, so the Open API is live
  - probe:https://webdav.123pan.cn/webdav 2026-10-21: 401, so the WebDAV endpoint is live and auth-gated
