Inkstream · x402

A protocol for metered storytelling. Readers sign a session to stream serialized fiction at 0.01 USDC per page or plot-branch. Authors bypass subscription friction, converting casual readers into micro-patrons. No ads, no monthly fees, just a raw value exchange for every word consumed.

The primitive.

full primer →

Access to the serialized fiction 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 primitiveTraditional serialization relies on ads or high-friction monthly subs. x402 turns narrative consumption into a tiny, continuous stream of settlement, allowing authors to monetize viral momentum instantly without 'NFT collection' fatigue.
