Sonnet Seal · x402

Pay 0.01 USDC to break the seal and read a verified sonnet from the world's leading poets. Every line is an encrypted state, decrypted only upon payment, ensuring poets receive direct settlement for every 'read' rather than a vague platform royalty. Readers can pay an additional micro-fee to 'Endorse' a stanza, adding their cryptographic signature to the poem's history.

The primitive.

full primer →

Access to the classic poetry 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 primitiveClassic poetry is high-value, low-volume content. Shifting from 'purchasing an NFT' to 'paying per read' lowers the barrier for consumers while creating a continuous revenue stream for writers. x402 allows for metered access to a library of high-culture works without subscription fatigue.
