The LeadFinch API is an Email matching engine, and is used to search for an Email address by using at least a first name, last name, and a domain. There is a limit of 6 calls per minute; an application may be blocked if it goes over this limit. The LeadFinch API returns calls in JSON format, and requires an API Key. LeadFinch offers a proprietary engine, and a chrome extension to help in searching for business Emails.
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.
