Free tier	Unlimited total storage on the free 普通版: '无限制的总存储空间，分享免登录，不限制下载流量，不限速，不限制下载次数'. Per-file cap is the binding constraint, and it is tier-set in 个人中心 → 文件升级. unit unlimited; metered on stored-bytes
Price	none stated
Per-object cap	Per-file cap widely reported at 100 MB (100000000 bytes)
Retention	not stated
Egress	Explicitly unmetered: no download traffic limit, no speed limit, no download-count limit, and shares download without login.
Identity	institution derived from the record's prose, not from an identity field, and no signup was executed: r, which is the hardest registration gate in this slot. No API means any large-scale use depends on an unofficial wrapper that breaks when the web form changes. Unlimited total x 100
Limits	per-object-cap Per-file cap widely reported at 100 MB source Per-file cap widely reported at 100 MB for free (raised per-account via the 文件升级 setting; Share links are public by design. Registration requires 手机号 + SMS code.
Binding	per-object-cap the per-object cap sets the shard size and therefore the object count; it bounds the total more tightly than any headline quota
Interface	unknown wrapper-only
Tooling	No official API. Community wrappers exist (lanzou uploader scripts, `lanzou-api` style repos); the browser upload form is the only documented path.
Composes with	Unlimited total x 100 MB per object is the pure 'per-record unlimited' shape the brief asks about: 20 TiB = ~210k objects. Registration needs a mainland phone number, so chaining is bounded by SIM supply, not by quota.
Reliability	Registration is SMS-gated on a Chinese mobile number, which is the hardest registration gate in this slot. No API means any large-scale use depends on an unofficial wrapper that breaks when the web form changes.
Notes	Unlimited total storage on the free 普通版: '无限制的总存储空间，分享免登录，不限制下载流量，不限速，不限制下载次数'. Per-file cap is the binding constraint, and it is tier-set in 个人中心 → 文件升级.

Free tier	Unlimited total storage on the free tier: '拥有无限制的总存储空间'. The per-file cap is 100 MB, and share links are permanent unit unlimited; metered on stored-bytes
Price	none stated
Per-object cap	100 MB per file on the free tier: '不限空间大小，不限下载速度，只是限制文件大小，最大不超过100M/个文件' (100000000 bytes)
Retention	Share links are stated to be permanent: '分享文件地址永久有效'. Account retention is not published
Egress	Free and explicitly unmetered: '下载不限速度，不限流量，不限次数，免登录下载'. The free product is ad-funded and the FAQ states 我们对下载速度不做任何限制 free_allowance: unlimited
Identity	country-phone registration moved to accounts.woozooo.com and asks for 手机号 plus an SMS code with no email path and no documented foreign-number path
Limits	per-object-cap 100 MB per file on the free tier source request-rate no WebDAV on a free account; access is only through direct-link extraction source
Binding	per-object-cap The total is genuinely unlimited and the egress is genuinely free, so nothing about capacity or traffic binds. 100 MB per object over a 10 TiB working set is 105,000 objects, which makes the file count the problem before the bytes.
Interface	rest
Tooling	no official API. A mature unofficial Python wrapper, zaxtyson/LanZouCloud-API with 811 stars and PyPI lanzou-api 2.6.10, does login, list, upload, download, delete, move, folder operations and direct-link extraction, and its README claims it works around both the file-type and the per-file size limits by splitting
Composes with	Unlimited total times 100 MB per object is the pure per-record-unlimited shape: 20 TiB is about 210,000 objects, all inside one free account's allowance. The gate is that registration is SMS-only on a mainland number
Reliability	Domains rotate constantly, across lanzou.com, lanzoue, lanzouj, lanzoux and lanzoul, and a share link that works on one suffix 404s on another, so a script must carry a domain list. The CDN host itself is geo-flaky. Two seed waves disagree on the free total, one saying unlimited and another 5 to 10 GB
Notes	The cleanest example in the corpus of the per-record-unlimited pattern, and the per-file cap is the entire cost. Two seed waves disagreed on the total, one saying unlimited and another 5 to 10 GB; the vendor's own page says unlimited and that is what is recorded, with the disagreement named.
