VoodooVox provides detailed demographic information on phone numbers. They source this information by mapping the number against numerous 3rd party databases typically used by the direct mail industry.
This data feed is available to developers via an API. Developers pass in phone numbers, and demographic info is returned. Users have access to city, state, zip code, and cell carrier for any phone number queried through the API with 200 fields available. Caller Analytics submits call records in real-time through the API giving users an analytics portal for their call activity. The API uses RESTful calls and responses are formatted in JSON.
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.
