Team Bitcoin,
We're happy to release BtcHook to the public:
https://www.btchook.com BtcHook a system built in-house for our use in a different project, and we thought others could make use of it, too.
Using BtcHook you can subscribe to any Bitcoin address, and receive notifications whenever an incoming payment is sent to that address. Notifications are sent using SMS, email, and webhooks to your specified URLs.
In addition to addresses, you can also subscribe to transactions, and get notified once the transaction has the required number of confirmations.
BtcHook has complete APIs, so you can manage your subscriptions either programmatically or through the dashboard
Much like gmail, BtcHook is in beta. We look forward to getting comments from the community as we continue exposing more and better features.
Ciao,
BtcHook
