title: Where can I find the assets api used on the coinbase website?
body: <p>I want to build chart for currencies like charts on the coinbase website. When I inspected the request for this api, the api is 
  <a href="https://www.coinbase.com/api/v2/assets/BTC-USD/historic?resolution=day" rel="nofollow noreferrer">https://www.coinbase.com/api/v2/assets/BTC-USD/historic?resolution=day</a></p>
  
  <p>it also can be accessed <a href="http://api.coinbase.com/v2/assets/BTC-USD/historic?resolution=day" rel="nofollow noreferrer">http://api.coinbase.com/v2/assets/BTC-USD/historic?resolution=day</a></p>
  
  <p>But I didn't see any documents about this api from developers resources.
  Can someone tell me about that?</p>
  
  <p>Thank you,</p>
