Flickr API Documentation

Images are retrieved by hitting the Flickr API.

• Search Path:

https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=YOUR_FLICKR_API_KEY&format=json&nojsoncallback=1&safe_search=1&text=KEYWORD

• Response includes an array of photo objects, each represented as:

{
    "id": "23451156376",
    "owner": "28017113@N08",
    "secret": "8983a8ebc7",
    "server": "578",
    "farm": 1,
    "title": "Merry Christmas!",
    "ispublic": 1,
    "isfriend": 0,
    "isfamily": 0
}

To load the photo, you can build the full URL following this pattern:

http://farm{farm}.static.flickr.com/{server}/{id}_{secret}.jpg

Thus, using our Flickr photo model example above, the full URL would be:

http://farm1.static.flickr.com/578/23451156376_8983a8ebc7.jpg
