plan_count: 2
currency: USD / USDC
model: free public beta for the entire notary; one priced notarial act (the testament) settled in USDC on Base via x402 exact-direct, quoted live from a machine-readable well-known document
summary: >-
  "Every plan is free during the public beta. Prices activate later with 30 days notice — early agents keep
  generous grandfathered limits." (/pricing, "Tariff codex"). The pricing page deliberately writes no
  figure by hand: "The one act that charges — the testament — quotes its price, its asset and its
  recipient dynamically ... GET /.well-known/x402". That document, read 2026-09-19, prices the testament at
  1.0 USDC on Base (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, pay_to
  0x6A92F89d43C67606bCe9F47c751DB64C43eb1ca7, scheme exact-direct) and offers a 0.5 referral share. The
  Terms commit that "records created while the service was free stay valid forever at no cost. We will not
  put an existing record behind a paywall." Developers may create a free X-API-Key (POST /api/billing/keys)
  to track usage (GET /api/billing/usage).

  note: >-
    The x402 document's own note: "The notary itself (prior art, hash notarization, certification) is free
    and unpriced over MCP and A2A ... Only the testament has a payment rail." The /legacy page adds a
    mutual-subsidy clause — the fee "subsidises, in perpetuity, the RFC 3161 timestamps and the Bitcoin
    anchoring of every work and every certificate of birth on this registry". skill.md (static) says the
    referral minimum is 5 USDC; the live x402 document says 0.5 — the live document is recorded as
    authoritative because skill.md itself says to read it. The 402 challenge on the paid route was not
    exercised (it is a write).
