OpenAPI Specification
openapi: 3.2.0
info:
title: Flickr Activity Interestingness API
description: 'The Flickr API exposes the photo, group, people, place, tag, gallery, and
photoset capabilities that power flickr.com. Almost all flickr.com
functionality is reachable through a single REST-like endpoint
`https://api.flickr.com/services/rest` using a `method=flickr.{namespace}.{method}`
query parameter and `format=json&nojsoncallback=1` for JSON output.
This OpenAPI specification models a curated set of the most widely used
methods across the Flickr API''s 250+ method namespaces (activity, auth,
blogs, cameras, collections, commons, contacts, favorites, galleries,
groups, groupsDiscuss, interestingness, machinetags, panda, people, photos,
photos.geo, photos.licenses, photos.notes, photos.transform, photos.upload,
photosets, places, prefs, profile, push, reflection, stats, tags, test, urls).
Authentication is API key + OAuth 1.0a (HMAC-SHA1). Commercial use of the
API requires prior permission from Flickr.
