Settlement-service billing is not activated for this synthetic evaluation workflow. Separate API checks settle per call in Base L2 USDC / Circle EURC (x402 v2); operators and enterprise workflows purchase instant ck_live_ card quota keys or $99 batch packs via Stripe (Operated by JUANA LIMITED, UK Co. No. 14043409). No fee is charged by this synthetic evaluation workflow. Existing API checks are a separate legacy offer.
