Free tierNo separate quota — it is a free image server over items you already hold, one image per item. Capacity therefore follows the 1TB/item rule.

Pricenone stated
Per-object cap1TB/item (1000000000000 bytes)
RetentionOne image per item for reliable IIIF (multiple images need multiple items); must upload to the 'Community Image' collection or the viewer breaks; test-style uploads can be deleted after 30 days. (30 days)
EgressFree, and it is a rendering endpoint, so one stored master serves arbitrary region/size/rotation/quality requests — the cheapest possible way to serve image bytes at many sizes
Identityinstitution (placeholder) inferred from the category 'academic'; the source record states no identity cost, so this is a class assumption, not evidence

Bindingper-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
Interfacerest, rclone rest
ToolingIIIF Image API v2 and v3 (Cantaloupe server); any IIIF viewer or plain GET on /iiif/<identifier>/info.json; no rclone backend
Composes withStore one large master per item, then let clients request tiles/thumbnails instead of originals — cuts served bytes by orders of magnitude for an image-heavy 500GB-1TiB/day workload. Multiply by unlimited items.
