Concert Crawler enables users to sign in with their Spotify credentials and receive a curated list of upcoming concerts for their favorite artists based on their listening history. It works by making requests to Spotify’s API with the user’s credentials in order to retrieve the relevant listening history, and then making a second round of requests to Eventful’s API, retrieving a list of upcoming concerts for each artist.
