Terms

Effective 20 October 2026. By creating an account, using an API key, or using the MCP server or hosted Verify Gate, you agree to these terms.

What the service does, and what it does not

Xyntherium Verify checks whether an answer is supported by the sources you supply. Verdicts describe whether the supplied passages support each claim. They do not establish whether any claim is true in the world. A verdict is not legal, medical, financial or compliance advice, and it is not a certification. You decide what to send to your customers; Verify is one input to that decision. The multi-model chat app shows answers from several AI models; they can be wrong, and you should check anything important.

Your account and keys

• Keep your API keys secret. You are responsible for use of your keys until you revoke them.
• One person or organisation per account; do not share an account to avoid plan limits.
• You must be at least 16, and able to agree to these terms for yourself or the organisation you act for.

Your content

You keep all rights to the questions, answers and documents you send. You give us permission to process them only to provide the service (including sending text to the model providers named in the privacy policy). Only send content you have the right to send. Don’t send special-category personal data (health, biometric and the like) unless you have a lawful basis to and you accept the retention described in the privacy policy.

Acceptable use

• No unlawful content or use, and no use to harass, deceive or harm people.
• No attempts to get around plan limits, rate limits, authentication or billing, and no load testing without our written agreement.
• No attempts to reach other customers’ data, or to extract the hosted service’s private parts (its prompts and model-escalation logic). The open-source parts are yours to use under the MIT licence.
• Don’t present a Verify verdict as a certification, or as a statement that something is true, lawful or safe.

Plans, billing and cancellation

• Prices and allowances are on /pricing (Verify) and inside the app (the multi-model chat). Paid plans renew each month (or year, where offered) until you cancel.
• Verify overage on Builder and Team is billed after the period at the published rate per 1,000 checks, and stops at three times the allowance.
• Cancel any time from Billing; the plan runs to the end of the period paid for. Charges are not refunded except where the law requires it or we say otherwise in writing.
• We may change prices for future periods with at least 30 days’ notice by email. Allowances may be adjusted as we measure costs; a reduction applies from your next period.

Availability and changes

We work to keep the service running, but we do not promise it will be uninterrupted or error-free. We may change or retire features, and will give reasonable notice before retiring one you pay for. Rule changes that affect verdicts are versioned and published in the changelog.

Warranty and liability

The service is provided “as is”. To the extent the law allows, we disclaim implied warranties, including fitness for a particular purpose. We are not liable for indirect or consequential losses, or for decisions made on the basis of a verdict. Our total liability for any claim is limited to the amount you paid us in the 12 months before it. Nothing here limits liability that cannot be limited by law.

Ending

You can stop at any time and ask us to delete your account. We may suspend or close an account that breaks these terms, and will tell you why unless the law or security prevents it.

Governing law

These terms, and any dispute arising from them or from the service, are governed by the laws of the State of Texas, United States, without regard to its conflict-of-laws rules.

Changes to these terms

We will update the date above and, for a material change, email account holders at least 30 days before it applies. Continuing to use the service after that means you accept the new terms.
