Pros & Cons from Real Users

Pros

  • API functionality is strong and they have good knowledge base to find helpful articles. Easy to get started too.
  • API is very simple and easy to use, not only is their REST API intuitive, but they also have a good Python wrapper.
  • Was good until they locked up my money. The user interface is ok, API integrations are good. Support was responsive until, it seems, they started collapsing.

Cons

  • Crypto price glitches that cost me thousands and awful customer support.
  • API documentation is lacking when it comes to more advanced and programmer-based tasks. Also, retrieving historical prices mostly just returns 0.
  • They are flat out refusing to withdraw funds. No apology, no explanation. I tried calling during business hours - no one picks up. Then I realized there are no reviews of this company anywhere. Seems they're likely having liquidity problems. Notice, there are no reviews of them anywhere. This is Sketch Central, not a legitimate brokerage.
