rate.sx VS bananopy

Coinbase has API endpoints that require no authentication. For example:

https://api.coinbase.com/v2/exchange-rates?currency=BTC

There's a convenient API at rate.sx also, on a more hobby/personal scale.

And in some client/node libraries (example), you can find this unit:

To actually give out the banano, you use your private key to sign a send block (which contains information of your account, your new amount and the destination and some other info). You can take a look at an example JSON request here. You would send a standard POST request to a node. GoBanano provided the sufficient framework for creating the blocks and balances but didn't have a wrapper for the RPC calls. Libraries such as bananojs or bananopy provide wrappers and are easier to setup/use. prussia dev's opensource banano faucet also contains a lot of the logic you may need to setup a faucet. Hope this helps!

There's nothing stopping the community from arbitrarily defining 19 decimal places as a new unit. There is already one such arbitrary unit, banoshi, which has 27 instead of the full 29 decimal places.
