For the second week in a row, over 30 different APIs were used to build new apps in our mashup directory. Those 20 mashups used 31 different APIs. And once again not all of those APIs are the usual suspects. Less common ones used include Formula 1 Racing data API Ergast, the new Etsy API and Twilio API, the ecommerce pay-per-action LinkShare API, the Zemanta API, the Sunlight Labs API, and short URL expander LongURL. And in what's clearly the new number one, the Twitter API was used in 4 of this week's mashups. The list below shows which APIs were used by which mashups:
