Self-serve stays $1 minimum, pay-as-you-go, no promises. Growth and Scale add reserved throughput, uptime SLAs, and real support response times — priced honestly above self-serve, because reliability isn't free to build.
Drag to your monthly token volume. See the real number on all three tiers before you talk to anyone.
No tier is ever cheaper per-token than the one below it. You're paying for guarantees, not a discount.
Two separate charges, two separate rhythms. Neither one runs on trust.
The Growth or Scale monthly fee is charged on day one of your cycle — before the period starts, not after. This is what funds your SLA, reserved throughput, and support commitment.
Every token you use is deducted from a live balance the instant the request completes — not billed monthly in arrears.
// fires inside the same transaction as the deduction
if balance <= last_topup * 0.20:
trigger_auto_recharge() # async, non-blocking
if balance <= 0:
reject_request(402)
If you're planning for a specific committed volume - hundreds of millions to billions of tokens a month - that's a custom reserved-capacity quote, not a self-serve tier. Locked-in rate, short-term commitment, no long lock-in.
