Prepay & save — bonus minutes lower your rate.
Volume credits
There is no contract and no monthly commitment. Adding credit has one floor: the smallest top-up is $20, because Stripe's processing fee eats too much of anything smaller. $100 is not a minimum — it is simply the first prepay that earns bonus credit on top. Credits expire one year from purchase.

What's in the rate
The 10¢ covers everything.
Most voice providers quote you one number, then bill you separately for the speech, the transcription, the AI, and the phone line — so the real cost only shows up at the end of the month. We built all of it ourselves and run it on our own hardware, including the phone lines we provision for you. So the rate is the rate. Nothing underneath it, nothing to add up, nothing to be surprised by. If you would rather keep your own telecom account, you can bring it — the rate does not change, and your carrier bills you directly for their per-leg cost.

FAQ
The quiet questions.
How does billing work?
One flat rate — $0.10 per minute of talk time — covers AI voice, inbound + outbound calls, WebRTC rooms, transcripts, recordings, and automation. Minutes meter by the second. On the default setup we supply the phone side, so the carrier cost sits inside the rate as well. If you bring your own telecom account instead, that is the one thing billed outside the rate — your carrier invoices you directly for their per-leg cost.
Are STT, TTS, and LLM usage billed separately?
No. The speech-to-text, text-to-speech, and language models are self-hosted and included in the 10¢. There is no per-token or per-character markup — the rate is the rate.
How do prepay credits lower my rate?
Prepaying loads bonus minutes on top of your balance — from +10% at $100 up to +300% at $50,000+. The bonus pulls your effective rate down to as low as 2.5¢/min. Credits are usage-based, not a subscription, and expire one year from purchase.
Do you charge for failed or dropped calls?
You’re billed for connected talk time only. Calls that never connect — busy, no-answer, failed dispatch — don’t consume voice minutes. If you bring your own telecom account, your carrier may still bill their own attempt fees.
Do WebRTC rooms count as voice minutes?
Yes — room participant-minutes meter at the same $0.10/min as phone calls, so there’s nothing new to learn on the bill.
Can I bring my own telecom provider?
Yes, though you do not have to — by default we provision and configure the number for you. If you would rather keep your own account, Telnyx, Twilio, and Plivo are supported as bring-your-own (BYO): you keep your carrier relationship and numbers, the platform handles dispatch, concurrency, and the AI stack, and your carrier bills you directly for their per-leg cost.
Is there a contract or minimum?
No contract and no monthly commitment. The one floor is on funding the account: the smallest top-up is $20, since card processing fees eat too much of anything smaller. Prepay tiers are optional and only exist to lower your rate at volume — $100 is the first tier that earns bonus credit, not a barrier to placing a call.
Ready to hear it?
Set up an agent, give it a number, and hear it make a call. Trying Rexa in the browser is free and needs no card. Phone calls are separate: there are no free credits or trial minutes, so placing real calls requires prepaid credit at the per-minute rate.
