API

API Redesign

Currently the API is mainly used internally for Cordova application, but does not follow good practices in API design.

And since its the most requested feature on UserVoice, project was launched to evolve the API.

API Basic Documentation

Reading a product

See http://fr.openfoodfacts.org/data or http://en.openfoodfacts.org/data

The requested subdomain will be the locale fetched.

Searching for products

You can add &jqm=1 to search results pages on the web site to get results in a jquerymobile format.

Also:

• sort_by=unique_scans_n
• page_size=50 (20 by default, 1000 at most)
• page=2

e.g. http://world.openfoodfacts.org/cgi/search.pl?search_terms=coke&search_simple=1&jqm=1

Posting photos

• Photos post on /cgi/product_image_upload.pl

code: the barcode
imagefield: "front"

var foodfact = { barcode : '3073780969000', name : 'KIRI GOUTER 280G 8 PORTIONS', energy: 500, energy_unit: "kJ", weight: 282 };
var postData = {
code         : foodfact.barcode,
user_id      : "mesinfosnutritionelles",
password     : "****",
product_name : foodfact.name?foodfact.name:foodfact.shop_label,

• Translate the data page (http://fr.openfoodfacts.org/data) in English and make it available on all subdomains
• Document all current API
• Write further API specifications
