Clearbit offers solutions for developers to construct business intelligence APIs. Using the Clearbit Person API, users can lookup employee information by using a contact's email to return available data on the person. This information includes applicable social profiles, Twitter & Facebook handles, avatar URLs, and basic information such as name, location, and biography. All calls and responses with the Clearbit REST API are done in JSON formats over a secure SSL connection. Clearbit also offers other services such as company lookup, OFAC verification, and geolocation. The API is able to take up to 600 calls per minute. Webhooks are offered for calls that require processing time. Clearbit also offers Ruby & Node.js bindings for the API.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
