  • The problems with APIs… •  Discovery (Endpoints, capabilities, etc.) •  Access (API keys, secrets, etc.) •  RTFM (A pain when you are in hack mode!) •  Data massaging (Conversion, filtering, etc.) •  The more, the merrier, NOT 7 <h#p://en.wikipedia.org/wiki/File:The_Scream.jpg>  
  • YQL #FTW 8 Make data access easy for the web!

  • Finding videos on YouTube… SELECT * FROM youtube.search WHERE query="russell peters" 13
  • 14 Stock quotes, anyone? SELECT * FROM yahoo.finance.quotes WHERE symbol IN ("YHOO", "AAPL", "GOOG", "AMZN”, “FB”);
  • 15 Search craigslist… SELECT * FROM craigslist.search WHERE location="sfbay” AND type="sss” AND query="dj mixer"
  • 16 One-line URL shortener… INSERT INTO yahoo.y.ahoo.it (url, keysize) VALUES ('http://9to5mac.com/', 5)
  • 17 Retrieve my Yahoo! contacts SELECT * FROM social.contacts WHERE guid=me
  • Accessing private data •  Use the endpoint http://query.yahooapis.com/v1/yql •  Requires OAuth for authentication http://developer.yahoo.com/oauth/guide/index.html •  Use one of our SDKs – https://github.com/yahoo 18
  • 19 1000+ APIs
  • How do I get data from YQL into hacks? 20 •  YQL is a REST API in itself and has two endpoints •  Public endpoint requires no authentication: http://query.yahooapis.com/v1/public/yql?q=query&format=format •  The private endpoint requires OAuth credentials: http://query.yahooapis.com/v1/yql?q=query&format=format •  Supported output formats: JSON, XML •  Use your favourite programming language!
  • YQL is open! 21 •  You can get your data tables into our system! •  Just write an XML schema and put it on GitHub - https://github.com/yql/yql-tables •  Example: craigslist search table - https://github.com/yql/yql-tables/blob/master/ craigslist/craigslist.search.xml
  • 22 Or, host your own table and use ‘USE’! USE ‘http://www.mysite.com/ myTable.xml’ as mytable; SELECT * FROM mytable WHERE key=“value”; <h#ps://www.flickr.com/photos/weldhouse/3083969633/>  
  • 23 There are a lot of things you can do with YQL. Your imagination is the limit.
