There seems to be quite a few pros in this thread - what are your thoughts on using
https://www.blockchainapi.org/ ? I came across them in my quest to find a reputable site to generate and monitor new wallet addresses. There's no long sign up process required!
I should also add that
https://www.blockchainapi.org/ is:
Simple and easy to use -> All it takes is one simple API request and you've got a payment address ready to give to your customer. Funds will be forwarded directly to your Bitcoin address, and you'll receive HTTP notifications when payments are received.
They are safe and secure -> the API and backend systems are secured with HTTPS and high-grade firewalls. Bitcoins are transferred to you ASAP, so there's nothing to worry about!
They are tested and error-free -> APIs have protections in place for every possible problem, so you won't have to worry about strange errors or issues when using the API.
Hope you enjoy using there services just as I have!
