I have a simple mobile app which can be used to query online crypto exchange APIs for live updates.
The test version was working fine till some time ago, but it doesn't seem to work anymore now.
I think something has changed on the API endpoint.
I need someone experienced with Coinbase or Blockchain APIs to review the API code and make necessary modifications to make it work again.
I need someone who can start immediately.
I am looking for a mix of experience and value
