Testnet is an almost-exact clone of bitcoin, except the bitcoins on testnet are valueless (the testnet blockchain resets every once in a while). It’s much smaller than the bitcoin block chain, and allows developers (and beta testers) to test out apps without the risk of losing money if something goes wrong. You can read more about testnet here.

I’ve provided an API which lets you transfer testnet bitcoins to an address of your choosing. It’s limited by IP address, so you’ll need to respect the limits. For non-developers, the documentation demo below serves as a web-based faucet. If you’d like to donate back to the faucet, send coins to motBKJbh4a67dNYeESjkkKbyfArrBwijN2. Happy developing :)
