CanonicalHash ("we", "our", or "us") provides deterministic JSON hashing and EIP-712 attestations via a pay-per-call API.
We do not require accounts, API keys, or personal information. Payments are verified on-chain via the x402 protocol (USDC on Base or Solana). We do not store your wallet address; the blockchain handles settlement.
When you canonicalize a JSON payload, the data is processed in memory to generate a hash and an EIP-712 signature. We do not permanently store your payloads. The attestation is returned to you instantly.
