Metering is ENFORCED: every metered call lands in the usage ledger as it settles, GET /keys/me reflects the real accumulation, and the hard ceiling answers a typed 402 OFFER from accumulation with the auth.vin reauthorization handoff. Bursts answer a typed 429 with retry_after. No terms document binds these prices yet: they remain stated intent, posted so no price is ever an ask."
