Look into Coinbase's tip service: https://www.coinbase.com/tip

As well as ChangeTip: https://www.changetip.com/

It might be what you're looking for, unless you want to custom build something. In that case also give Chain.com a look as well as Blockcypher.com.

Coinbase also has some nice developer products, their api: coinbase.com/docs/api/overview

and if you want to do anything relating to raw bitcoin data (the blockchain and all transactions) i.e., run a node, I'd recommend Toshi.io, an open-source node that is very easy to query. Quite a few people run this thing on an AWS tier.

Hope that helps if you want to dabble with a bitcoin project for your site :)
