API rate limit

QuadrigaCX seems to operate an out-of-band support group on reddit. From a question posted 2018-01-01:

"You're limited to 30 calls per minute on both the public and private APIs to allow you to get a feel for the API. Once you have managed to trade efficiently, we can consider removing these limits."

quadrigacx.api's Issues

API no longer works because QuadrigaCX has applied for creditor protection

Calls to the API return a "301" error with the following text:

Our site is down for maintenance. We apologize for the inconvenience this may cause. We appreciate your patience, and will keep you updated as we know more. Thank you.

Message from QuadrigaCX Board of Directors

January 31, 2019

Dear Customers,

An application for creditor protection in accordance with the Companies' Creditors Arrangement Act (CCAA) was filed today in the Nova Scotia Supreme Court to allow us the opportunity to address the significant financial issues that have affected our ability to serve our customers. The Court is being asked at a preliminary hearing on Tuesday February 5 to appoint a monitor, Ernst & Young Inc., as an independent third party to oversee these proceedings.

For the past weeks, we have worked extensively to address our liquidity issues, which include attempting to locate and secure our very significant cryptocurrency reserves held in cold wallets, and that are required to satisfy customer cryptocurrency balances on deposit, as well as sourcing a financial institution to accept the bank drafts that are to be transferred to us. Unfortunately, these efforts have not been successful. Further updates will be issued after the hearing.
