Terms of Service

_Version 2026-08-06 · last updated 6 August 2026_

These terms cover the Dvaarik Voice API at developers.dvaarik.com and api.developers.dvaarik.com. They are between you and Dvaarik AI, Hyderabad, India. Using the API means you accept them.

1. What the service is

We give you a speech-to-speech engine over a WebSocket. You send audio, we transcribe it, run your prompt through a language model, and stream speech back. You bring your own telephony, or none at all.

We are not a telephony provider. We do not sell you phone numbers, minutes, or a carrier relationship, and we do not place calls on your behalf unless you connect your own carrier account and instruct us to.

2. Your account

One account, one owner. You are responsible for everything done with your API keys, so treat them like passwords: they are shown once, and you can revoke any of them at any time from the console.

You must be able to enter into a contract in your jurisdiction. If you are signing up on behalf of a company, you confirm you are allowed to bind it.

3. Credits, and what happens to them

The wallet is prepaid. There is no subscription, no card on file, and no invoice at the end of the month for usage you have already had.

• Calls are billed per minute, rounded up. A 61-second call bills as two minutes. The rate for a call is fixed when the call is created, so a price change never applies retroactively to a call already in flight.
• A call is admitted only if your balance covers it running to its full length at your rate. This is why a call can be refused while your balance is not zero.
• Consumed credits are not refundable. The compute, speech recognition and speech synthesis behind a completed call are bought and paid for by us at the moment it happens; we cannot return what has already been spent.
• Unconsumed credits can be refunded on written request to dev@dvaarik.com, less any payment-processing cost we have already borne. Allow 7–10 working days.
• Credits do not expire, and they have no cash value beyond use on this platform. They cannot be transferred between accounts.
• Welcome credit granted at signup is promotional. It is spendable on the platform and is never refundable in cash.

Prices are in Indian Rupees. Dvaarik AI does not hold a GSTIN, so no GST is charged or collected and no tax invoice is issued; the invoice you receive is a payment receipt.

4. Acceptable use

Do not use the API to:

• place calls to people who have not agreed to be called, or in breach of TRAI, DND, or 140-series rules — outbound compliance is yours, and if you connect your own carrier you are the caller, not us;
• impersonate a real person or organisation, or represent the agent as human when asked directly;
• generate content that is unlawful, that harasses, or that sexualises minors;
• reverse-engineer, resell or white-label the engine as your own product without a written agreement with us;
• probe, load-test or attack the infrastructure beyond your own account's documented limits.

We can suspend an account that is doing any of the above. Where the reason is not a legal emergency we will tell you why, and unconsumed credits are refundable in that case.

5. What you own, and what we do not take

Your prompts are yours. Your audio is yours. The transcripts are yours.

We claim no licence over any of it and do not use it to train models. See the Privacy Policy for what is and is not retained — the short version is that prompts and transcripts are never written to our database.

6. Availability

We aim for the service to be up, and we run it on the same infrastructure our own products depend on. We do not offer a contractual uptime guarantee on the self-serve plan. If you need one, write to dev@dvaarik.com.

Third parties are involved — speech and language model providers, and the payment gateway. An outage at one of them can be an outage for you.

7. Limits of liability

To the extent the law allows, our total liability for any claim is limited to the credits you have spent with us in the three months before it arose. We are not liable for lost profits, lost business, or the consequences of what an AI agent said on a call. You are responsible for what your prompt instructs the agent to do.

Nothing here excludes liability that cannot lawfully be excluded.

8. Changes

We may change these terms. Material changes will be announced by email to the address on your account at least 14 days before they take effect, and the version number at the top of this page will change. Continuing to use the API after that means you accept the new version.

9. Ending it

You can stop using the API at any time and ask for unconsumed credits back under section 3. We can end the agreement with 30 days' notice, or immediately for a breach of section 4 — in either case unconsumed credits are refunded.

10. Law

These terms are governed by the laws of India, and the courts at Hyderabad, Telangana have exclusive jurisdiction.
