PlotProof · x402

Pay-per-query validation for story premises against a global narrative database. Writers sign with the embedded wallet to pay 0.01 USDC and run their logline through an LLM that checks for tropes, clichés, and existing IP. Every check settles on-base, providing a cryptographic receipt of 'narrative proof-of-work' and creative timestamping. Eliminate the friction of minting; focus on the utility of verification.

The primitive.

full primer →

Access to the story idea validation 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 primitiveShifts the value from a static NFT 'claim' (which often holds little legal weight) to a metered utility service. By charging per validation call, the platform creates a high-velocity feedback loop for creators while establishing an on-chain ledger of creative provenance via settlement hashes.
