SABnzbd API compatibility1.x

infinidysk implements the SABnzbd-compatible operations used by Sonarr, Radarr, and similar download clients. It is not a complete replacement for SABnzbd’s administrative API.

Supported operations

Every operation is a mode= value on /api:

• version, status, fullstatus, get_config, and get_cats
• server_stats and warnings since 1.1.0
• addfile and addurl
• queue listing, plus name= actions delete, pause, resume, priority, and move since 1.1.0
• switch for placing one queued job at another job’s position or an absolute queue index since 1.2.0
• pause, resume, and speedlimit since 0.9.0
• change_cat for per-job category changes on queued items since 1.1.0
• retry for failed history re-queue (single or bulk) since 0.9.0
• history listing and history&name=delete

Other modes and queue actions are not implemented.

Queue and history filters accept both cat and category. The default category sentinel returned by get_cats is *.

Queue and history search since 1.2.0

Queue and history listing accept a literal, case-insensitive search term over both the job name and NZB filename. Search is not regular-expression syntax. They also accept one cat/category and one status; comma-separated filter lists are not supported. Queue statuses are Downloading, Queued, and Paused; history statuses are Completed and Failed. History additionally accepts failed_only=1 as shorthand for status=Failed.

The admin UI uses infinidysk-specific sort and dir=asc|desc parameters for display-only ordering. Queue supports name, category, status, and size; history also supports completed. Text sorting is case-insensitive. Unknown sort values retain the endpoint’s normal order. Queue display sorting never changes download priority or physical queue order.

Pause, resume, and speed limit since 0.9.0

mode=pause / mode=resume stop and restart new queue dequeues. Workers already downloading finish naturally unless a per-job pause cancels them. WebDAV mounts keep serving — pause does not interrupt playback. Queue JSON reports paused accurately. Items added with SAB priority -2 (Paused) are skipped until their priority changes; queue slots report status: Paused for those jobs.

Per-job pause and resume accept UUID(s) via value (comma-separated or repeated) or a JSON body {"nzo_ids":["…"]} on mode=pause, mode=resume, and the queue&name=pause / queue&name=resume aliases. Without ids, pause/resume applies to the whole queue coordinator (legacy global behavior).

mode=queue&name=priority sets priority for one or more jobs. Pass the SAB priority code as value2 (or priority): -2 Paused, -1 Low, 0 Normal, 1 High, 2 Force. Paused uses the same per-job pause path as queue&name=pause.

mode=switch&value=<nzo_id>&value2=<nzo_id-or-index> moves one queued job to the target’s original position and returns {"result":{"position":N,"priority":P}}. Moving across priority bands adopts the target priority. Moving a paused job into a non-paused band resumes it by clearing its scheduled retry delay. The infinidysk-specific queue&name=move&value2=0|top bulk action remains the shortcut for move-to-top.

mode=change_cat sets category for queued jobs (not actively downloading). Pass cat / category plus job id(s) in value or nzo_ids. Categories must match configured API categories.

mode=retry re-queues failed history items. Accepts a single value id or multiple ids (comma-separated / repeated value, or nzo_ids JSON). Bulk retry returns nzo_ids for successes and a failed array with per-item errors when some items cannot be retried. History bulk actions in the admin UI do not change category on retry (category is copied from the history row).

mode=speedlimit is accepted and stored and reflected in queue JSON (speedlimit / speedlimit_abs). Byte-accurate download throttling is not enforced yet — that work is tracked in #375.

Queue JSON reports live throughput for in-progress jobs since 1.1.0: per-slot timeleft (H:MM:SS, or D:HH:MM:SS past 24h), plus queue-level timeleft, kbpersec (KB/s), and speed (human units such as 1.3 M). Queued and paused slots report 0:00:00. status / fullstatus include paused, speedlimit, and speedlimit_abs; live speed stays on mode=queue.

Intentional differences

• Job identifiers are UUIDs rather than SABnzbd_nzo_* strings. Treat them as opaque values.
• Responses are JSON. The output=xml option is not implemented.
• Queue and history roots contain the fields needed by supported download clients rather than every SABnzbd UI field.
• History has no separate archive tier. history&name=delete permanently removes matching history rows.
• Ignore SAB history limit can ignore a client’s limit; infinidysk still enforces a server-side maximum page size.
• Authentication failures use HTTP error status codes instead of always returning HTTP 200 with an error body.
• Active queue workers stay pinned at the front and are never preempted. A switch targeting that pinned prefix lands at the first waiting job; active sources cannot be moved. Negative queue indexes are rejected.
• server_stats aggregates provider bandwidth from retained ProviderHourly rollups (plus folded lifetime totals for all-time bytes). The per-server daily map and article counters are bounded by the hourly retention window — pruned buckets are not reconstructed.
• warnings returns recent Warning-and-above log entries from the in-memory buffer. name=clear is accepted for SAB client compatibility but does not clear the buffer (support packs rely on it). Use Settings → Support to collect the full warning log.

addurl and private / LAN hosts since 0.8.0

mode=addurl fetches the NZB from the URL the download client supplies. Before each hop (including redirects), infinidysk rejects destinations that resolve to a non-public IP — an SSRF guard that also blocks Docker DNS / RFC1918 indexers unless allowlisted.

Allow destinations under Settings → SABnzbd → Trusted local hosts (api.addurl-trusted-hosts):

Entry	Meaning
prowlarr / hydra.lan	Hostname match (case-insensitive)
192.168.1.50	Exact IP
192.168.1.0/24 / fd00::/8	CIDR for resolved addresses
*	Trust any non-public address (disables the guard)

Only list hosts you control. Prefer mode=addfile when the client can upload the NZB itself.

The same allowlist can be set with TRUSTED_INTERNAL_HOSTS when the UI setting is empty — Environment variables.

Delete behavior

Queue delete accepts UUID(s), repeated value parameters, value=all, or value=all with cat / category to clear only that category. SAB del_files=1 has no extra effect (no incomplete-download directory).

History delete accepts UUIDs, value=all, or value=failed. The admin UI can delete mounted content for completed jobs with infinidysk-specific del_completed_files=1 — download clients should not send this after importing a symlink/STRM, or playback sources disappear. The history UI also offers Clear failed and Clear all actions that call history&name=delete with value=failed or value=all.

A History row vanishing after a successful Arr import is expected SAB-client cleanup, not a missing mount. Typical triggers: the Arr’s Remove Completed download-client option, infinidysk Automatic Queue Management rules (those send removeFromClient=true, independent of Remove Completed), or a WebDAV DELETE of a /completed-symlinks/<category>/<release> folder. Those paths remove the history row and clear HistoryItemId; the WebDAV files stay.
