| Free tier | No separate quota — it is a free image server over items you already hold, one image per item. Capacity therefore follows the 1TB/item rule. unit mixed; metered on unstated |
|---|---|
| Price | none stated |
| Limits | One 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. |
| Identity | institution (placeholder) inferred from the category 'academic'; the source record states no identity cost, so this is a class assumption, not evidence |
| Egress | Free, 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 |
| Per-object cap | 1TB/item (1000000000000 bytes) |
| Retention | One 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) |
| Interface | rest, rclone rest |
| Tooling | IIIF Image API v2 and v3 (Cantaloupe server); any IIIF viewer or plain GET on /iiif/<identifier>/info.json; no rclone backend |
| Composes with | Multiply by unlimited items. |
| Reliability | Third-party workshop doc, not IA's own page. |
