OpenBazaar API Ruby Client

Build Status Code Climate Test Coverage

A simple OpenBazaar API client for Ruby.


Add the gem to your Gemfile:

gem 'obarc', github: 'inertia186/obarc'


$ bundle install


require 'obarc'

session = 'username', password: 'password')

profile = session.profile
  {"website": "website",
   "public_key": "b7d8f6ee04453e1babde87d12198ecd14be00aa998e85636767d8b00d2603e6d",
   "primary_color": 16777215,
   "background_color": 12832757,
   "email": "[email protected]"}}
session.update_profile(email: '[email protected]')
{"success": true}
{"peers": [["", 28467]], "num_peers": 1}

If you want to manually upload an image, this will return the image hash.

session.upload_image(image: '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')
{"image_hashes": ["a89810619833ef29d373c124ce05f362a313929e"], "success": true}

You can also add a new listing with image URLs in the hash. The client will upload them and save the image hashes to the contract.
