**How YesGraph Works:** YesGraph can recommend who each user should invite. We tune our ranking by learning about past users and past invites. Then you send a user’s contacts, and we send back a ranked list.

Here are the endpoints you’ll need:
* **Users** to help us understand what typical users look like. This also helps us filter out current users from invite flows as needed. [/users](doc:users)
* **Past Invites** to help us understand what kinds of relationships. For example, is your app more about family, friends, or coworkers? [/invite-sent](doc:invite-sent) and [/invite-accepted](doc:invite-accepted)
* **User Contacts** to tell us who we might suggest. [/address-book](/v0/docs/address-book#post-address-book)
* **Ranked Contacts** to get the ranked results out. [/address-book/:user_id](/v0/docs/address-book#get-address-bookuser_id)
