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 sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it.
