<ul>
<li><code>GET /api/checkout</code> request to retrieve information about the merchant.
</li>
<li><code>POST /api/checkout?total=${amount}</code> request to retrieve a valid base64 transaction for the wallet owner to sign. Once it is signed, the wallet then submits this transaction to the blockchain to proceed the transaction.
