Per-token rates

Usage is billed per million tokens in USD — no subscriptions, no per-seat fees. The figures below are each provider's own published list price, shown for scale; the rate Mayoo bills you is the one on the live per-model table, which is generated from the same billing chain that charges your balance.

Pricing questions

Is there a free tier?

Signing up is free. Token usage requires prepaid credits — the minimum top-up is $5 USD.

Will my balance expire?

Prepaid balance stays valid for 1 year from your most recent top-up, and a top-up of any amount renews your whole balance for another full year. We email you 7 days before a balance is due to expire, and we never auto-deduct maintenance fees.

What payment methods are supported?

Credit and debit cards via Stripe (USD). Apple Pay and Google Pay are available where Stripe supports them.

Refund policy?

Unused balance from a top-up can be refunded for a limited window after the charge — proportional to the credit you have not spent, less a processing fee. The window and the fee are stated in our Terms of Service (§5), which governs.
