Free tier	anonymous guest read of the whole mount list, and a write on one path; no account, no payment, no published quota unit unlimited; metered on none
Price	none stated
Per-object cap	between 100 MiB (200) and 110 MiB (413 from the Cloudflare front); the operator publishes no cap
Retention	until the operator's disk or Cloudflare account fails; no TTL, no SLA, no notice
Egress	served through Cloudflare; the reader pays nothing and the operator pays nothing per byte
Identity	anonymous no registration, no token, no cookie; /api/me returns a guest session with role 1 and permission 256
Limits	write-gated writable on the guest path only; /api/fs/remove returns 403, so nothing can be deleted per-object-cap 413 from Cloudflare between 100 MiB and 110 MiB per-ip-shaping ~1.9 MB/s up, ~1.0 MB/s down on a home uplink
Binding	write-gated The write is real but undeletable, capped by the CDN body limit, and rate-limited by one home uplink, so the binding constraint is the gate on writing at all, not a quota.
Interface	rest, webdav rest endpoint: https://data.yanshiqwq.cn/api/fs/put
Tooling	OpenList v4.2.7 REST (/api/fs/*) and its WebDAV endpoint; rclone's alist backend speaks the same REST
Composes with	the only verified write in 170 hosts: a 4 KiB PUT, a GET, and a SHA-256 match. Useful as a one-object staging area, not as capacity. One instance on one operator's disk, so a second account carries no second allowance here. The composition angle is the pattern and not this host: a public OpenList that returns write true is the candidate class, and the index lists are where the census finds them
Reliability	One volunteer's home disk behind Cloudflare. No quota, no SLA, no delete, and the bytes are world-listable once written.
Notes	The only host of 170 that accepted a write and gave the bytes back. It passes the zero-byte oracle with 'file exists', reports permission 256 with no bit 3, and is writable only because a per-path meta overrides the role. Probes left 32-byte files named *-r6probe.bin in its root, because delete is denied.

Evidence (4)

date	source	what it proved
2026-10-22	probe:https://data.yanshiqwq.cn/api/fs/list	HTTP 200, code 200, 27 root entries, write:true and write_content_bypass:true, provider:unknown
2026-10-22	probe:https://data.yanshiqwq.cn/api/fs/put	PUT of 32 bytes returned {"code":200,"message":"success"} and GET /p/ returned the same 32 bytes with a matching SHA-256
2026-10-22	data.yanshiqwq.cn/api/public/settings	OpenList v4.2.7, build 2026-10-15, allow_indexed false, allow_mounted false
2026-10-22	probe:https://data.yanshiqwq.cn/api/me	guest session, role 1, permission 256 = bit 8 (WebDAV read) only, with no bit 3; the write is granted by a per-path meta, not by the bitmask
