Cambridge Digital Library IIIF APIs is one of 12 APIs that [University of Cambridge](https://apis.io/providers/university-of-cambridge/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include IIIF, Digital Collections, Library, Linked Data, and Cultural Heritage. The published artifact set on APIs.io includes API documentation.

The Cambridge University Library digital collections platform exposes IIIF Presentation API 2.1 manifests at cudl.lib.cam.ac.uk/iiif/<item-id> and IIIF Image API 2.1 endpoints at images.lib.cam.ac.uk/iiif/<image>.jp2/info.json, both on the institution's own domain. Verified live: the manifest for MS-ADD-03996 (Newton's Trinity College Notebook) returns 247KB of application/json declaring @type sc:Manifest against the IIIF presentation/2 context, and the matching info.json returns application/ld+json with the image/2 context, tile sizes and scale factors. A supporting metadata service at services.cudl.lib.cam.ac.uk serves TEI XML per item. Institution-built and institution-operated — not a vendor discovery layer.
