/v2/accounts/{principal}

Get the account data for the provided principal

Where balance is the hex encoding of a unsigned 128-bit integer (big-endian), nonce is a unsigned 64-bit integer, and the proofs are provided as hex strings.

For non-existent accounts, this does not 404, rather it returns an object with balance and nonce of 0.
