We’ve just rolled out three new features for the CrunchBase API, all implemented based on feedback from our early users.

The first is the new “list” action that returns the name and permalink for all entities in CrunchBase of a certain type. For example:

http://api.crunchbase.com/v/1/companies.js

rapidshare downloads

The second new feature is a “search” action. To search across CrunchBase for entities matching a given keyword or keywords, use:

http://api.crunchbase.com/v/1/search.js?query=techcrunch

The third feature is JavaScript callbacks, which are enabled for both the exisiting “show” API action and the new “search” action. For example:

http://api.crunchbase.com/v/1/search.js?query=techcrunch&callback=callme

This request returns JavaScript that will call the function callme with the API data as a single argument.
