Q:

Is there a site to monitor Bitcoin or Altcoin addresses if funds were received or sent?

Looking for a service that can email/sms you if a monitored bitcoin/altcoin address has any moved funds. Is there such a service for this?

A:

Check out blockcypher.com's API, they provide webhook callbacks (i.e. HTTPS notifications) for different types of events, including transactions being confirmed or attaining a certain confidence level.
I think block.io's API can do something similar, however that is more oriented around their own web wallet, i.e. for monitoring addresses in a wallet managed through them, rather than arbitrary addresses.
