Critiq · x402

Turn the 'starving artist' trope into a high-fidelity feedback loop. Critiq operates as a metered critique engine where every peer review, redline, or technical teardown is a paid micro-transaction. By putting a $0.01 price tag on the 'Approve' or 'Comment' button, you filter for skin-in-the-game insights while ensuring the reviewer is compensated for their eye. Every critique is a signed HTS transfer receipt, creating a verifiable provenance of an artist's growth.

The primitive.

full primer →

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

Why this primitiveTraditional peer review is often low-effort or sycophantic. By introducing x402 micropayments, we monetize the 'expert eye' and turn feedback into a professional service rather than a favor. This creates a data-rich ledger of professional validation that agents can use to verify talent.
