Free tier	1024 MiB per file, no account, no per-account cap — unlimited uploads. Retention 3 to 100 days, scaled by file size via MIN_AGE + (MAX_AGE - MIN_AGE) * (1 - size/max_size)^2, so small files live ~100 days and near-max files ~3 days. unit unlimited; metered on unstated
Price	none stated
Per-object cap	1024 MiB per file (1073741824 bytes)
Retention	Retention 3 to 100 days, scaled by file size via MIN_AGE + (MAX_AGE - MIN_AGE) * (1 - size/max_size)^2, so small files live ~100 days and near-max files ~3 days (100 days)
Egress	free direct HTTPS GET from x0.at, no redirect, no metering; Content-Length served correctly and range requests supported.
Identity	anonymous derived from the record's prose, not from an identity field, and no signup was executed: 1024 MiB per file, no account, no per-account cap — unlimited uploads. Retention 3 to 100 days, scaled by file size via MIN_AGE + (MAX_AGE - MIN_AGE)
Limits	per-object-cap 1024 MiB per file source per-object-cap 1024 MiB/file source retention-clamped Retention 3 to 100 days source 1024 MiB/file; 3-100 day retention driven by size; no accounts so no listing or bulk delete; deletion only by knowing the URL.
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	rest, rclone rest
Tooling	plain curl multipart: curl -F file=@x https://x0.at/ (also -F keep_name=1, -F id_length=N). ShareX and Hupl configs published. Open-source server: github.com/Rouji/filehost2 (37 stars). No rclone backend.
Composes with	unlimited anonymous uploads at 1 GiB each with random IDs; the only chaining needed is a client-side index of returned URLs. 10 TiB hot set = ~10,000 uploads. Retention is the binding constraint, not quota.
Reliability	Longest-lived 0x0 derivative still accepting uploads. Provenance is a hobby VPS; no durability guarantee and expiry is silent and size-dependent. Treat as a 3-8 week cache tier, not archive.
Notes	1024 MiB per file, no account, no per-account cap — unlimited uploads. Retention 3 to 100 days, scaled by file size via MIN_AGE + (MAX_AGE - MIN_AGE) * (1 - size/max_size)^2, so small files live ~100 days and near-max files ~3 days.
