node package manager



fullcontact is a Node.js module that wraps the fullcontact API. It implements the following API endpoints:

Build status

Build Status


The module is distributed through npm (node package manager) and can be installed using:

npm install fullcontact --save

The --save automatically adds the module to your package.json definition.


We are all hackers in our heart that's why this module is build with extensibility and hackibility in mind, there aren't any hidden components and all the API endpoints are implemented as separate constructors so they can be improved and hacked when needed.

You requirement the module as any other node.js module:

'use strict';
var FullContact = require('fullcontact');
// The constructors are directly exposed on the FullContact constructor: 

To create a new client you simply need to construct the module with your FullContact API key:

var fullcontact = new FullContact(api);

Alternatively you can also use the provided createClient method, is that's how you roll.

var fullcontact = FullContact.createClient(apikey);
// Or just call it directly: 
var fullcontact = require('fullcontact').createClient(apikey);

The initialized FullContact client will have some properties that you might find useful:

  • remaining The amount of API calls you have remaining
  • ratelimit The amount of API calls you're allowed to do
  • ratereset When your rate limit will be reset again in EPOCH

Please note that these properties are all set to 0 until you have made your first request to the API server as these values are parsed from the response headers.

Error responses

This API implemention will return an Error object when the FullContact response is returned without a status: 200 so it could be that your operation is queued for processing. That's why all returned error's have a status property which the returned status code (unless it's a parse error or a generic error). So just because you got an error, it doesn't mean that your request has failed.


Turn your semi-structured data in fully structured location data. This Location endpoint is namespaced as a .location property. It has 2 optional arguments.

  1. casing How is the provided location cased?
  • lowercase for lowercased names (john smith)
  • titlecase for Title Cased names (John Smith)
  1. includeZeroPopulation will display 0 population census locations. The provided value should be a boolean.

fullcontact.location.normalize('denver', [casing], [includeZeroPopulation], fn);

Normalize the location data.

fullcontact.location.normalize('denver', function (err, data) {

fullcontact.location.enrich('denver', [casing], [includeZeroPopulation], fn);

Retrieve more information from the location API.

fullcontact.location.enrich('denver', function (err, data) {


The Person endpoint is confidently namespaced as a .person property. Each person API has an optional queue argument which you can use to indicate that this request will should be pre-processed by FullContact and that you want to fetch the details later. According to the API it should to receive the value 1 as queue.

The following methods are available on this API:, [queue], [webhookUrl], [webhookId], fn);

Retrieves contact information by e-mail address. Supports the use of webhooks by providing an url and id.'', function (err, data) {
});'', null, '', 'webhooktracker', function (err, data) {

person.md5(address, [queue], fn);

Retrieves contact information by e-mail address but transforms the email to an MD5 first.

fullcontact.person.md5('', function (err, data) {

person.twitter(handle, [queue], fn);

Retrieves contact information by Twitter username.

fullcontact.person.twitter('3rdEden', function (err, data) {

person.facebook(handle, [queue], fn);

Retrieves contact information by Facebook username.

fullcontact.person.facebook('john.smith', function (err, data) {
});, [queue], fn);

Retrieves contact information by phone number.'+13037170414', function (err, data) {


Reduce the number of anonymous subscribers by detecing of the user is subscribing with a real e-mail address or just a one time address The Email endpoint is namespaced under the .email property.

email.disposable(email, fn);

Checks if the given e-mail address was disposible.'', function (err, data) {


The name API has an optional casing argument. The value of this optional argument can either be:

  • lowercase for lowercased names (john smith)
  • titlecase for Title Cased names (John Smith)'John Smith', [casing], fn);

Normalize a name.'John Smith', function (err, data) {
});{ email: '' }, [casing], fn);

Name deducing. Unlinke other API's this API should receive an object with either an email or username property which you want to use to substract the information.{ email: '' }, function (err, data) {
});{ username: '3rdeden' }, 'lowercase', function (err, data) {
});'john', 'johnny', [casing], fn);

Check the similairity of between two names.'john', 'johnny', function (err, data) {
});{ name: 'john' }, [casing], fn);

Retrieve some statistics about the name. Just like the name deducer API this API only accepts an object that receives either a givenName, familyName or both.{ name: 'john' }, function (err, data) {
//{ givenName: 'john' }, [casing], fn); 
//{ familyName: 'smith' }, [casing], fn); 
//{ givenName: 'john', familyName: 'smith' }, [casing], fn); 
//'john smith', [casing], fn);

Parses the name to determin the likelyhoot that this is really a name.'john smith', function (err, data) {


The tests are written against the live FullContact API. They can be ran using:

API_KEY=<key> npm test

Don't worry if you forget it, we'll throw an error and let you know ;-).
