Freebase is a masculine but complicated human-curated database.

Nodejs is a straight-talkin language that takes no guff


  npm install freebase


  var freebase= require('freebase');
  freebase.description('tom cruise', {})
  //"Tom Cruise, is an American film actor.."

Showin' off

it's built to be as flexible as possible. all methods return the same things:

  freebase.image("/en/thom_yorke", {})
  freebase.image("thom yorke", {})
  freebase.image("", {})
  freebase.image({"name":"thom yorke", "id":"/en/thom_yorke"}, {})
  freebase.image(["/en/radiohead","thom yorke"], {})

it's a good idea to include your api_key in each method:

  freebase.sentence("meatloaf", {type:"/food/food", key:"MY_API_KEY"})

the paramaters are lazy, if you're lazy.

Video Demo

In the friggin browser

Demo - freebase.min.js == 63kb

  <script src=""></script>
  <script src=""></script>
    $.freebase.description("tony hawk", function (r){

In the shell:

the library can be run in the console, with the optional second parameter as the method:

 freebase george clooney
   # {  "mid": "/m/014zcr", "id": "/en/george_clooney" ... } 
 freebase sentence george clooney
   #"George Timothy Clooney is an American actor, film director, producer, and screenwriter." 

Writing to Freebase:

Oauth is hard, but you can do it.


  • Register a project at and enable the Freebase API
  • In the 'Credentials' section, create a new Client ID -> 'installed application', 'other'
  • Add your data to './auth/credentials.js'
  • Run node ./auth/authenticate.js
  • You will be given a url to visit in your browser, which gives you an OAuth code.
  • Paste the oAuth code, and you'll be given the end tokens.

thats all you need to include in your request:

  freebase.add_type("/en/the_who", {type:"/music/artist", token: your_access_token})
  freebase.add_alias("/en/melanie_chisholm", {alias:"Sporty Spice", token: your_access_token})

You'll need to get a new token after about 3 hours. (Don't commit your credentials.)

Each method takes the following form:

freebase.method( "query", {options}, callback() ) it supports this form:

freebase.method( "query", callback() ) and also this form, where the callback defaults to console.log()

freebase.method( "query" )

here are some options that you can ship in to any method:

{ nodeCallback: true, // use the 'error-first' callback form -> callback(error, result){}
  key: "MY_API_KEY", // good idea to include your freebase key, to avoid errors
  limit: 2, // truncate results
  debug: true, // print out the urls being fetched

Basic methods


MQL documentation

Books about planets:

  var query=[{
    "type":  "/astronomy/planet",
    "name":  null,
    "/book/book_subject/works": []
  freebase.mqlread(query, {}, function(r){console.log(r)})

the options object will ship any paramaters to the freebase api.


Every Tornado, ever

  freebase.paginate(query, {max:400})
