I built a discord bot to analyze the market of the OldSchool Runescape game once a public and fairly accurate item price API was launched. The bot initially started as a fairly simple interface to display the real-time prices and graphs with the price history, but then as the core features were completed, it evolved into finding price spikes and dumps using simple algorithms. Once the user base increased I released a paid membership to get the best notifications while keeping other features free, and it grew organically from there! It's only been few months since it launched but it's generating well over $1k/m revenue so far.
