Google Search autocomplete API?
autocomplete, google-search-api
Solution
The new url is:
http://suggestqueries.google.com/complete/search?client=firefox&q=YOURQUERY
the client part is required; I did't test other clients.
[EDIT]
If you want the callback use this:
http://suggestqueries.google.com/complete/search?client=chrome&q=YOURQUERY&callback=callback
As @Quandary found out; the callback does not work with client "firefox".
[EDIT2]
As indicated by @ user2067021 this api will stop working as of 10-08-2015: Update on the Autocomplete API
Problem
Does Google provide API access to autocomplete for search like on the actual site? I have not been able to find anything. I would like to use Google's autocomplete logic for web search on my own site which relies on Google's search API.
