Creator here. While growing my product, Telemonetize, a service that allows to charge a monthly subscription for access to your Telegram group or channel, I found myself going into the crypto market.<p>I quickly found out that crypto payments are 'push' payments, meaning that for a user to pay, let's say, $10/mo in cryptocurrency, he/she has to send the payment manually himself/herself every month. There is no universal solution for 'pulling' from a crypto wallet. Any solution that 'pulls' from a customer's wallet is limited and requires your end user to have that specific wallet<p>I built this API to make your life easier while accepting crypto subscriptions. It's a simple API that notifies your subscribers automatically via email several times before their subscription expires so you don't have to do it manually. In these emails, there will be a link to a checkout page so they can renew their subscription<p>You will get notified via email and webhooks when users subscribe, renew or don't renew(cancel) their subscription<p>All you have to do is add an embeddable widget/button to your website<p>It's built on Ruby on Rails, with plain Javascript and Bootstrap on the front end and it's hosted on Heroku
