FEES · PUBLIC PRICE LIST
Fee schedule
CVIN is neutral registry infrastructure. Fees are published like an electricity tariff: writers (operators) pay nothing, ever; readers pay for history depth and freshness. Metered settlement happens on-chain and is independently checkable.
Four pricing commitments:
① Rule-based pricing — every price is on this page; nobody gets a private rate. ② 30-day notice — any change is announced here 30 days ahead. ③ Checkable settlement — every x402 pay-per-call is on-chain, with a transaction hash you can verify. ④ Writing is free — registration, attestation and certificates cost the writer nothing, permanently, so the supply side stays neutral.

What the free tier deliberately does not give you: the per-record timeline. Free resolve returns the count of observations in the last 90 days; the individual records are the paid tier. We state this on the device page with the exact numbers rather than hiding it behind a paywall.
