Pinterest states that additional partners will continue to be rolled out, as well as eventual permissions for everyone. The API allows Pinterest data to be shown on partner websites. The announcement explains:
“Now, if someone’s looking for Thanksgiving recipes on AllRecipes.com, they’ll see the most Pinned recipes from the site on the homepage. Or, they could go to Zappos.com to see which shoes Pinners covet most. You could use these APIs to show popular products on your homepage or to curate your top articles and other content on Pinterest at any given time. The Pins will regularly update, so you can always see what’s trending.”
The Pinterest API will have a wide variety of benefits for all sites, especially e-commerce and crowd-sourced content (or those with high engagement levels, like BuzzFeed). By pulling Pinterest data to determine the most popular pinned content, website visitors can view the most popular content (or e-commerce products) quickly, while website creators can see what is most popular and continue to create content and products their target audience is interested in.
