API Research

The bot could have a foursquare account, and poll locations for which coupons apply. Messaging that person with the coupon is the next hurdle. Need a mechanism for reaching them, foursquare doesnt seem to have one. Also it could feel spammy to get notified at random when checking in.

$ curl -u login:password


Even though we are not foursquare friends, the contact information is exposed. Most conviently the twitter handle is exposed. A twitter account for this same bot could public-tweeet @user you've got a $1 off coupon at store X for the next 15 minutes! Any good twitter client will pick up that tweet in search.
