All of the API's are working exactly as described below each of them. - How does your resolver work?
- This is like asking a chef to give his secret ingredient. In this case, we're the chef of our API's.

- Yes we'd love to, but since time is money, we charge a small service fee of $10 for such services.
- I see a login page, but no registration form. What's up?
