Hi,
We have been using your library on one of our servers. We keep having to make new keys because the old one stops working.
I have tested the following change with an old key and it works again:
function setExpire(url) {
var expireTime = String(Math.floor(Date.now()/1000) + 15);
if (url.indexOf("?") > -1) {
return url + '&expire=' + expireTime;
}
return url + '?expire=' + expireTime;
}
function get (url, callback) {
url = setExpire(url);
(...)
function post (url, param, callback) {
url = setExpire(url);

Out-of-order Processing
Sometimes network traffic can cause near-simultaneous API calls to arrive out of order. Since the nonce must always be increasing, an API call with a higher nonce may arrive earlier than a separate call with a lower nonce if they are initiated very quickly together. When this happens, the 2nd call will be dropped as invalid. To address this, a separate expire parameter can be included, specifying a unix timestamp after which the call will not process.
When the expire parameter is included, the nonce is ignored. We recommend setting the expire parameter to no greater than 15 minutes in the future to prevent replay attempts.
Example
