In his presentation today at Gluecon, John Musser ofProgrammable Web illustrated how hot APIs have become and how they’ve matured.
Perhaps most illustrative is his “API Billionaire’s Club.”
Members of the club include Google and Facebook with 5 billion AP calls per day. Twitter has 3 billion per day. Ebay has 8 billion per month. NPR gets 1.1 billion calls per month for its API-delivered stories. Saleforce.com gets 50% of its traffic through its API.
According to Musser, it took eight years to get to 1,000 API’s but just 18 months to get to 2,000. This year, the number of API’s are double what they were last year on a month-per-month basis.
