The interesting part to me is they are selling their service via mashape.com which is new to me. Its a neat marketplace for "cloud APIs". Some of the APIs are free or freemium. Here is a list of the most popular APIs:
- Facial recognition API
- Yahoo weather API
- Multilingual sentiment analysis of text
- IP utils
- Barcode / QR code generator
- DuckDuckGo Zero-click Info
- Bitly url shortner
- Whois
