Blocktrail is pretty much useless. It requires a complex MD5-hash/signature. Thanks but ... no thanks! Did you forget https provides integrity?

not a big fan of how u need an API key: not needed for calls to the blockchain.info API(which doesn't cover the testnet).

It may be a bit late, but for others coming to this question, [Blocktrail](https://www.blocktrail.com) have a data and wallet API that supports both Bitcoin mainnet and testnet.

The API provides HD wallets with multi-signature transactions (allowing for full control over your coins should anything ever happen to Blocktrail), and there are currently SDKs for [PHP](https://github.com/blocktrail/blocktrail-sdk-php), [NodeJS](https://github.com/blocktrail/blocktrail-sdk-nodejs) and [Python](https://github.com/blocktrail/blocktrail-sdk-python), with more coming soon.

There are also simple examples included in the SDKs to help you get started, a comprehensive [API documentation](https://www.blocktrail.com/api/docs), and a couple of working example projects:  
1. [Simple Bitcoin Wallet App](https://github.com/blocktrail/simple-bitcoin-wallet-app)  
2. [Simple Block Explorer](https://github.com/blocktrail/simple-block-explorer)
