List tasks
List background tasks for the authenticated user with optional filtering.
Results are ordered newest first. Returns 404 when library_id names a
library that does not exist or is not accessible to the authenticated user.
Authorizations
Gumnut API key (apikey_...) sent as a Bearer token in the Authorization header. Create and manage keys in the Gumnut app, or with the API key endpoints while signed in to it.
Query Parameters
Restrict results to tasks owned by this library. When omitted, returns tasks across every library the authenticated user owns.
Return only tasks currently in this execution status.
Status of a background task execution: pending (created and awaiting
processing), started (picked up by a worker and not yet in a terminal
state — the task may be executing or awaiting an automatic retry after a
transient failure), success (completed successfully), or failure
(failed and will not be retried).
pending, started, success, failure Return only tasks of this type.
Kind of background processing a task performs: image_quality
(historical only — scored an image's technical quality; this task type is
retired and no longer dispatched, the value appears only on old task
rows), embedding (compute the content embedding that
powers search), face_detection (detect faces in an asset),
face_clustering (group a library's detected faces into people),
asset_description (generate a natural-language description of an asset),
asset_storage_cleanup (remove stored files left behind by a permanently
deleted asset), asset_version_storage_cleanup (remove stored files of a
superseded asset version), reverse_geocoding (resolve an asset's GPS
coordinates to a place name), video_thumbnail_extract (extract a
thumbnail image from a video), video_metadata_extract (recover a
video's capture time, GPS location, and camera details from the file's
own metadata), thumbhash (compute the blurred
placeholder shown while a thumbnail loads), display_proxy_generation
(generate a browser-displayable rendition of an original the image CDN
cannot transform, such as an oversized or over-dimensioned file), or
burst_detection (detect rapid-fire shots of the same moment and stack
them).
image_quality, embedding, face_detection, face_clustering, asset_description, asset_storage_cleanup, asset_version_storage_cleanup, reverse_geocoding, video_thumbnail_extract, video_metadata_extract, thumbhash, display_proxy_generation, burst_detection Maximum number of tasks to return.

Successful Response
Unique task identifier with btask_ prefix
ID of the asset this task processes; null for library-scoped tasks such as face clustering

Also accepted by get_task_status in place of id.
Status of a background task execution: pending (created and awaiting
processing), started (picked up by a worker and not yet in a terminal
state — the task may be executing or awaiting an automatic retry after a
transient failure), success (completed successfully), or failure
(failed and will not be retried).
pending, started, success, failure Result summary produced by a completed task; null until success
Error detail from the most recent failed or retried attempt; not cleared by a later success, so it can be non-null on a task that failed transiently and then succeeded. Null if no attempt has failed
Retry and rescue bookkeeping value for this task. Zero before any automatic retry or stuck-task rescue; not guaranteed to be a cumulative delivery count
When the task record was created (ISO 8601); dispatch to the task queue follows separately, after the creating transaction commits
When a worker most recently began executing the task, or when the stuck-task reaper rescued it back to pending (ISO 8601). Because a rescue can re-enqueue a task no worker ever picked up, a non-null value does not prove a worker has run the task
When the task finished, whether successfully or not (ISO 8601); null until then
