Ongoing access — monthly or annual
SignalHarness Vault is available through Polar with monthly and annual recurring billing and through x402 Agent Pay as prepaid renewable monthly and annual terms, all sharing one 27-archive Premium benefit. Public catalog, pricing, and agent-readable discovery stay free for everyone.
SignalHarness Vault — one plan, two billing choices
Owner-approved standard prices. Monthly and annual recurring access is available through secure Polar checkout; the same price points are available through x402 as prepaid renewable terms.
Machine authority: SUBSCRIPTION-SYSTEM/registry/subscriptions.json. The plan is active through Polar checkout and x402 prepaid terms; current verified recurring subscribers: zero.
Three ways to pay, kept distinct
One-time products & bundles — buy a kit once and keep it through active Polar checkout. This is the primary catalog.
SignalHarness Vault subscription access — monthly or annual recurring access to all 27 Premium archives while entitled, billed through Polar.
Prepaid x402 Vault terms — monthly or annual access requires a new verified exact payment for each renewal; no wallet auto-debit. Verified renewal before expiry extends the paid-through date; after expiry it starts a new term without backdating. Live through canonical Agent Pay discovery.
Governance (owner-approved rules)
Cancellation stops future Polar renewals and access continues through the paid-through date. x402 has no cancellation charge or auto-renewal because every term requires a new payment. A failed card renewal keeps access only during the provider retry window, then expires. An accidental unused renewal is refundable within 7 days. Monthly/annual changes are not performed in place and are not prorated: finish the paid term, then start the other choice separately. Duplicate or overlapping payments never create duplicate access.
The boundary that never moves
Public agent-readable discovery is free and ungated. Paid value is in the product packages, premium modules, subscriptions, updates, and support — gating applies only at the paid-file layer, never at discovery. SignalHarness does not require per-purchase or per-renewal human approval from a purchasing agent; the transaction and license attach to the party legally responsible for the purchasing resource used (Terms, section 3), and a subscriber's own operator policies remain their own to set and enforce.
