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 libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
