assets

Update an asset

Edits the user-editable metadata for a single asset — description, GPS coordinates, and original capture datetime. Only fields included in the request body are changed; others are left untouched. Passing null for a field removes a previously-set value; the response then falls back to the value embedded in the file when present. latitude and longitude must be set together (both written or both cleared).

Setting or clearing GPS coordinates re-enqueues reverse geocoding so location names refresh against the new effective coordinates.

For editing multiple assets in one round trip, prefer bulk_update_assets.

patch/api/assets/{asset_id}

Path parameters

asset_idstring required

Asset ID (with asset_ prefix) of the asset to update.

Request body

descriptionstring nullable

User-set description for the asset. Pass null to remove a previously-set value (the response then falls back to the description embedded in the file, if any). Omit to leave unchanged. Distinct from the AI-generated description field on the response — this writes to metadata.description.

latitudenumber nullable

GPS latitude in decimal degrees, [-90, 90]. Must be set together with longitude. Pass null (along with longitude=null) to remove a previously-set value; omit to leave unchanged.

longitudenumber nullable

GPS longitude in decimal degrees, [-180, 180]. Must be set together with latitude. Pass null (along with latitude=null) to remove a previously-set value; omit to leave unchanged.

original_datetimestring date-time nullable

When the asset was originally captured. Aware values store the offset from utcoffset() alongside; naive values store NULL offset. Pass null to remove a previously-set value — the response then falls back to the datetime embedded in the file when present, otherwise to the file's upload timestamp. Omit to leave unchanged.

Response

Successful Response

idstring required

Unique asset identifier with 'asset_' prefix

mime_typestring required

MIME type of the file (e.g., 'image/jpeg', 'video/mp4')

original_file_namestring required

Original filename when the asset was uploaded

local_datetimestring date-time required

When the photo/video was taken, in the device's local timezone

created_atstring date-time required

When this asset record was created in the database

updated_atstring date-time required

When this asset record was last updated

metricsobject nullable

ML-generated quality scores and other metrics. null when not requested via include=metrics.

asset_urlsobject nullable

Named asset variants. Images: 'original', 'thumbnail', 'small', 'preview', 'fullsize'. Videos: 'original', plus 'thumbnail_image', 'small_image', 'preview_image', 'fullsize_image' pointing at the extracted still. 'original' is served with a Content-Disposition attachment header (signed 'dl' filename param) so a top-level navigation saves it to disk, while inline subresource loads (<video>, fetch) still render it. Variant URLs are stable: a derived variant may briefly 404 until its artifact is generated, then serve from the same URL.

descriptionstring nullable

AI-generated description of the asset's content, quality, and composition. null means description generation has not yet run; empty string means the model refused to describe the asset. Distinct from metadata.description (camera-embedded EXIF metadata).

thumbhashstring nullable

Base64-encoded ThumbHash placeholder (~28 chars). Clients decode with the thumbhash library (JS / Swift / Kotlin) to render an instant blurred preview before the CDN thumbnail arrives. null while generation is pending.

widthinteger

Width of the asset in pixels

heightinteger

Height of the asset in pixels

durationnumber nullable

Video length in seconds. null for images and for videos whose duration has not been extracted yet.

trashed_atstring date-time nullable

When this asset was moved to trash (ISO 8601, UTC). null for live assets. Trashed assets are excluded from default list/search results and are purged after the configured retention window.

stack_idstring nullable

ID of the stack this asset belongs to (asset_stack_ prefix), or null when the asset is not part of a stack. Group assets by this value to collapse a stack into a single tile; the stack's own cover and member count are not carried on the asset. Distinct from metadata.auto_stack_id, which is the camera's in-EXIF MakerNotes:AutoStackID string — this is the server-assigned foreign key to the asset's stack.
