CrunchBase, The Free Tech Company Database

CrunchBase is the free database of technology companies, people, and investors that anyone can edit.

Data

There is currently a bulk download but there is an API with home page at http://www.crunchbase.com/help/api.

The API provides JSON representations of the data found on CrunchBase. The API currently supports three actions: "show", "search", and "list", which are each described below.

The "v/1/" components of the URLs below refer to the current version of the API, which is 1.

Show Entity

To retrieve information about a specific entity on CrunchBase, use a URL of the form:

http://api.crunchbase.com/v/1/{namespace}/{permalink}.js

The available namespaces are:

• company
• person
• financial-organization
• product
• service-provider

{permalink} referrers to an entity's permalink as seen in the URL for its regular CrunchBase page.

Also, you can append a callback query param to have the result passed to a callback method of your choice.
Examples

api.crunchbase.com/v/1/company/facebook.js
api.crunchbase.com/v/1/person/brad-fitzpatrick.js
api.crunchbase.com/v/1/financial-organization/accel-partners.js?callback=callme

Search Queries

To retrieve a list entities that match a given search query, use URLs of the form:

http://api.crunchbase.com/v/1/search.js?query={keyword(s)}
