Flickr is the long-running photo, group, people, place, tag, gallery, photoset, and Commons platform now owned by SmugMug. Its REST-like API dispatches every operation through a single endpoint (https://api.flickr.com/services/rest?method=flickr.{namespace}.{method}), spanning ~250 methods across 30 namespaces — covering activity, auth, blogs, cameras, collections, commons, contacts, favorites, galleries, groups, group discussions, interestingness, machine tags, panda, people, photos (plus photos.geo / photos.licenses / photos.notes / photos.transform / photos.upload), photosets, places, prefs, profile, push, reflection, stats, tags, test, and URLs. Authentication is API key + OAuth 1.0a (HMAC-SHA1). Commercial use requires a permission-granted commercial key.
