<p>BlockExplorer doesn't work anymore for me (redirecting to testnet.blockexplorer.com which throws a 502) so I found a new alternative:</p>

<p><a href="http://tbtc.blockr.io/api/v1/coin/info" rel="nofollow">http://tbtc.blockr.io/api/v1/coin/info</a></p>

<p>You have to get the "last_block" element.</p>

<p>Blockchain.info does not track the testnet, but blockexplorer.com does. In fact the API you're using was originally from blockexplorer.com, and blockchain.info simply adopted it.</p>

<pre><code>wget -O - http://blockexplorer.com/testnet/q/getblockcount 2&gt; /dev/null
</code></pre>

<p>or shorter</p>

<pre><code>curl http://blockexplorer.com/testnet/q/getblockcount
</code></pre>

You have to get the "last\_block" element.
