Pricing

Text-to-speech is billed by the number of characters sent to the API (whitespace and SSML tags are not counted). Voice agents are billed per minute of conversation, with text-to-speech, speech-to-text, LLM inference, and orchestration all included — no passthrough fees.

No. Voice-agent minutes are all-in: LLM inference, speech-to-text, text-to-speech, and orchestration are included in the per-minute rate. No LLM passthrough, no per-token billing, and no annual commitment — the rate you see is the rate you pay, and you can cancel anytime.

Paid usage runs on a prepaid balance. You add funds — and can turn on auto top-up to add a set amount whenever the balance drops below a threshold — and we draw it down at the published per-character and per-minute rates, with no opaque credit units and no guessing what a call costs. Your monthly plan fee covers the included allowance; anything beyond it draws from the balance. The free tier has no auto top-up, so it simply stops at its cap.

Yes. You can upgrade or downgrade your plan at any time from the console. When upgrading, you'll be charged a prorated amount. When downgrading, the change takes effect at the start of your next billing cycle.

We accept all major credit and debit cards (Visa, Mastercard, American Express) as well as ACH bank transfers for enterprise plans. All payments are processed securely through Stripe.

No. Pay-as-you-go plans are month-to-month with no commitment. Enterprise plans can be structured as annual agreements with volume discounts. You can cancel at any time.

Paid plans include phone numbers — 1 on Starter, 5 on Pro, and 20 on Scale — provisioned from the console. On any plan, including Free, you can bring your own carrier (BYOC): connect your own SIP trunk or Twilio account at no extra cost.

The free tier is a hard cap: when you reach your monthly text-to-speech characters or voice-agent minutes, usage pauses until your next billing cycle (or you upgrade) — there's no auto top-up, so you're never billed for an overage. On Starter, Pro, and Scale there's no hard cap; usage beyond your included allocation draws down your prepaid balance at your plan's rate — text-to-speech at $10 per 1M on Starter, $8 on Pro, and $6 on Scale; voice-agent minutes at $0.075/min on Starter, $0.07/min on Pro, $0.068/min on Scale — with auto top-up keeping that balance funded so production never stalls. We'll notify you as you approach your limits.
