  summary: A Free and Simple API to Help You Find Something Better to Do
  description: The Bored API is a free, no-authentication public API that returns suggestions for things to do when you are bored. The canonical implementation is the open-source MEVN (MongoDB / Express / Vue / Node) project maintained by Drew Thoennes at github.com/drewthoennes/Bored-API. The historically hosted instance at https://www.boredapi.com/ has been intermittently or fully unreachable since 2024 (originally hosted on Heroku); community mirrors such as https://bored-api.appbrewery.com continue to serve the dataset. This specification documents both the v1 (legacy, activities-only) and v2 (activities + facts + riddles + websites + suggestions) surfaces of the canonical Drew Thoennes implementation so the API contract is preserved for self-hosting and historical reference.

  x-status-notes: The official hosted instance at https://www.boredapi.com/ is no longer reliably reachable. The reference implementation remains open source and can be self-hosted. The App Brewery community fork (https://bored-api.appbrewery.com) provides an actively maintained hosted mirror with a slightly different path scheme.
