description: >-
  Client-side and embeddable surfaces Adobe ships, distinct from the server-side SDKs in
  packages/. Adobe's component story is unusually large for an API provider because Spectrum is a
  full public design system, and because PDF Embed is a hosted viewer rather than a library.

families:

- family: PDF Embed API
  kind: hosted embeddable viewer
  docs: https://developer.adobe.com/document-services/docs/overview/pdf-embed-api/
  loader: https://acrobatservices.adobe.com/view-sdk/viewer.js
  registry: cdn
  version: null
  version_note: >-
    The loader URL is unpinned and floats to whatever Adobe currently serves — there is no version
    in the path and no CDN metadata endpoint to query. A consumer cannot tell which build they are
    getting, which is itself the finding.
  free: true
  credential: client ID from the Adobe Developer Console, domain-bound
  embed_modes: [full-window, sized-container, in-line, lightbox]
  capabilities:
  - High-fidelity PDF rendering in a web page
  - Annotation and commenting APIs
  - Analytics events for document interaction
  - Search-engine-indexable rendering
  - Modern viewer UI variant
