DoCurious API Reference / types / Challenge

Interface: Challenge

Defined in: types/challenge.types.ts:340

The central challenge entity -- a real-world activity users discover, complete, and document.

Remarks

Challenges are the core content unit of DoCurious. They are created by vendors, staff, or community users, then pass through a moderation workflow before appearing in Explore. Each challenge can have multiple ChallengeInstance offerings and optional ChallengeMilestone steps for structured completion.
