LNBook allows Lapp admins to query users by Twitter @screen_name, returning a list of services and LNURLs for that user (provided by the user) & optionally a fresh, Tippin.me invoice!
If you are a user, simply log in with Twitter, navigate to your dashboard, and enter LNURLs from your lapps.
If you are a lapp admin, try our API! Query /api/screen_name for a list of LNURLs associated with that screen_name, or query /api/getinvoice/screen_name if you also want to receive a fresh Tippin.me invoice for that user (if the user has a Tippin account).
Clone, npm install. Create a creds.js file in the project directory and add Twitter API credentials (use creds.example.js as a guide).
You will likely need to use 127.0.0.1:3000 for local development if using the Twitter API.
