It’s clear by the running total on the ProgrammableWeb homepage that there are a lot of APIs. In addition to a lot of companies with APIs, there are companies with a lot of APIs. Google has the most–surprised? You may be at some others than make the list, from social networks to online marketplaces.
- Google (113) isn’t surprising, nor is the company’s most popular API, Google Maps.
- Yahoo (57) comes in second, with the Flickr API its most popular
- XIgnite (56) may be a shock if you haven’t heard of the financial data firm before.
- Microsoft (39) has a reasonable place on the list, led by its Bing Maps API.
- Amazon (35) is fueled by its suite of AWS APIs, but its shopping API is tops.
- AOL (32) has only nine AOL-branded APIs. Its MapQuest brand has more than that.
- eBay (25) was a pioneer of web APIs and its listings API is still its most popular.
Notably missing are Facebook (10) and Twitter (4). Of course, quantity does not necessarily imply quality, but the latter is much harder to quantify.
