Commerce contract

Humans subscribe. Agents can pay per bounded verification.

BRIK64 separates payment from correctness claims. Payment unlocks access; evidence bundles report bounded verification results under explicit limits.

Stripe Checkout/Billing

Human SaaS plans and enterprise subscription path.

x402

First agentic pay-per-call rail for bounded verification API calls.

Stripe MPP/SPT

Card/Link based machine payments after Stripe profile readiness.

AP2

Enterprise mandate roadmap; not required for v1.

Claim boundary

A paid run is not a claim of universal correctness. BRIK64 returns run ids, receipt hashes, evidence hashes, verification levels reached, and explicit boundaries for what was and was not checked.
