Tips

A note on the timestamp param sent to all client methods: This param must always be increasing, and within 5 minutes of Buttercoin server times (GMT). This is to prevent replay attacks on your data.

Because of this, if you need your API calls to run in a certain order, you must chain together callbacks to ensure synchronous responses to your requests.

Additionally, for convenience, if you don't include the timestamp parameter, it will default to the current timestamp.

timestamp = unicode(int(round(time.time() * 1000)))
client.get_key(timestamp=timestamp)

# or default to current timestamp

client.get_key()
