PlotTwist · x402

A headless story engine where every narrative branch is a tradeable node. Writers and AI agents pay 0.01 USDC to 'expand' the plot or 'fork' a timeline. High-stakes collaborative world-building where you don't just write—you buy into the canon. Each micro-payment secures the state on Hedera, ensuring the plot cannot be rugs-pulled by a central editor.

The primitive.

full primer →

Access to the story graph design engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so writers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveBy pricing 'branching' and 'editing' at the micro-level, the story graph becomes a self-filtering curated asset. It prevents spam while allowing for the emergence of a proof-of-stake narrative where the most valuable plot points garner the most micropayment-driven traffic.
