Terms of Service and End-User Licence Agreement
Last updated: March 2026
1. Agreement
By accessing or using Axiom at axiom.xenta.pro or the associated playground at play.xenta.pro, or by installing or using any associated software including the CLI, SDK, or @xenta/* packages (collectively, "the platform"), you agree to these Terms of Service and End-User Licence Agreement ("Terms"). If you do not agree, you must stop using the platform immediately.
These Terms apply to all users including individuals, startups, and enterprise accounts. Where a separate written enterprise agreement exists, that agreement takes precedence over these Terms.
2. The service
Axiom provides cryptographic execution governance infrastructure. You may use the platform to verify operations, author and deploy policies, and access the ledger and audit trail associated with your account. Access is subject to available credits.
When credits are exhausted, access to all platform features — including the playground, policy management, and ledger — is suspended until credits are purchased. Existing ledger records are preserved.
No guarantee of outcomes. Axiom verifies operations according to configured policies and cryptographic rules. We do not guarantee the correctness, safety, legality, or business outcome of any operation submitted through the platform. Verification confirms that an operation satisfies the policy and structural rules you have configured — it does not constitute an endorsement of the operation, nor does it make Xenta responsible for any downstream consequence of that operation.
3. Licence grant
Subject to your compliance with these Terms, Xenta grants you a limited, non-exclusive, non-transferable, revocable licence to:
Access and use the Axiom platform via its web interface and documented APIs.
Install and use the CLI and @xenta/* packages solely for the purpose of integrating with the Axiom platform.
Access and use the platform documentation for internal purposes.
This licence does not permit you to:
Redistribute, sublicense, or resell any component of the platform or its software.
Embed the CLI, SDK, or @xenta/* packages in a competing product or service.
Use the software outside the scope of integration with the Axiom platform.
Nothing in these Terms transfers ownership of any intellectual property to you.
4. Credits and billing
Credits are purchased in blocks with a minimum purchase of $20.
Credits are consumed per verified operation at the rate corresponding to the operation tier.
Credits do not expire.
Credits are non-refundable once consumed.
Unused credits may be refunded within 40 days of purchase, provided no operations have been run against them. Refunds apply only to fully unused credit blocks. Partially used credit blocks are not eligible for partial refunds.
We reserve the right to withhold refunds in cases of suspected fraud or abuse.
In the event of a disputed charge, contact us at axiom@xenta.pro. Refund eligibility is determined solely under the conditions stated above.
QUANTUM tier pricing is negotiated separately and is not available via self-serve.
5. Acceptable use
You may use Axiom for any lawful purpose. You may not:
Use the platform to facilitate illegal activity.
Attempt to reverse engineer, tamper with, or circumvent the verification system or the Policy Safety Kernel.
Submit operation payloads containing malware, exploits, or harmful code.
Use the platform in a way that degrades service for other users.
Resell or sublicense access to the platform without a written agreement with Xenta.
Use automated scraping, bulk extraction, or programmatic access beyond the documented API without a written agreement. This includes tunnelling the platform's verification infrastructure into competing systems.
Access or attempt to access another user's account, data, or ledger records.
Use the platform in violation of applicable export control or sanctions laws. Access may be restricted where required by law, including restrictions required by US export regulations given our use of US-based AI and cloud providers.
6. The ledger
Operations verified through the platform are written to an immutable hash-chained ledger. This is a core architectural property of the system — ledger records cannot be deleted, modified, or reversed by you or by Xenta. By submitting an operation for verification, you accept that a permanent record of that operation will be stored on the ledger.
7. Intellectual property
The Axiom platform, including its software, design, documentation, and trademarks, is owned by Xenta. You retain ownership of the operation data and policies you create on the platform.
You are solely responsible for the legality, accuracy, and appropriateness of the data you submit to the platform.
You may not use Xenta or Axiom trademarks, logos, or branding without prior written permission.
8. Availability and warranties
The platform is provided as-is and as-available, without warranties of any kind, express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the platform will be uninterrupted, error-free, or free of harmful components.
SLA commitments are available only on enterprise accounts under a separate written agreement. We will make reasonable efforts to maintain availability and notify users of planned downtime.
9. Limitation of liability
To the maximum extent permitted by applicable law, Xenta, its directors, employees, and affiliates are not liable for any indirect, incidental, consequential, special, or punitive damages — including loss of profits, data, or business opportunities — arising from your use of or inability to use the platform.
Our total cumulative liability to you for any claim arising from these Terms or your use of the platform is limited to the amount you paid for credits in the 30 days preceding the event giving rise to the claim.
Nothing in these Terms limits liability for fraud, death, or personal injury caused by our negligence.
10. Indemnification
You agree to indemnify, defend, and hold harmless Xenta Ltd. and its directors, officers, employees, and affiliates from and against any and all claims, damages, liabilities, costs, and expenses (including reasonable legal fees) arising from: your use of the platform; your violation of these Terms; your violation of any applicable law or regulation; or your infringement of any third-party rights.
11. Force majeure
Xenta is not liable for any delay or failure to perform obligations under these Terms where such delay or failure results from causes beyond our reasonable control, including but not limited to outages of third-party infrastructure providers (including Firebase, Google Cloud, or Cloudflare), internet or network failures, natural disasters, pandemics, labour disputes, or governmental or regulatory actions.
12. Suspension and termination
Voluntary closure. You may close your account at any time by contacting axiom@xenta.pro. Unused credits eligible for a refund under Section 4 will be assessed at that time.
Termination for violation. We may suspend or terminate your account if you violate these Terms, with or without prior notice depending on the severity of the violation.
Immediate suspension. We may suspend your account immediately, without prior notice, where necessary to protect platform security, ledger integrity, or the interests of other users. This includes suspected abuse, fraud, or activity that threatens the cryptographic integrity of the system.
Upon termination for any reason, your access to the platform ceases. Ledger records are retained as described in the Privacy Policy.
13. Governing law and dispute resolution
These Terms are governed by and construed in accordance with the laws of the Federal Republic of Nigeria, without regard to conflict of law principles.
Any dispute arising out of or in connection with these Terms or your use of the platform shall be subject to the exclusive jurisdiction of the courts of Lagos State, Nigeria, unless otherwise agreed in writing between the parties.
Before initiating formal proceedings, both parties agree to attempt to resolve any dispute in good faith through direct negotiation for a period of 30 days from the date the dispute is raised in writing.
14. Changes to these terms
We may update these Terms as the platform evolves. The date at the top of this page reflects the most recent revision. For material changes, we will notify users via the platform or by email where feasible. If you do not agree to revised Terms, you must stop using the platform. Continued use after the effective date of revised Terms constitutes acceptance.
15. Miscellaneous
Severability. If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions will continue in full force and effect. The invalid provision will be modified to the minimum extent necessary to make it enforceable.
Waiver. Failure by Xenta to enforce any right or provision of these Terms does not constitute a waiver of that right or provision. Any waiver must be in writing and signed by an authorised representative of Xenta.
Entire agreement. These Terms, together with the Privacy Policy and any separate written enterprise agreement, constitute the entire agreement between you and Xenta regarding the platform and supersede all prior discussions, agreements, or representations.
Assignment. You may not assign or transfer your rights or obligations under these Terms without prior written consent from Xenta. Xenta may assign these Terms in connection with a merger, acquisition, or sale of assets.
No Agency / No Partnership. Nothing in these Terms creates a partnership, joint venture, employment, or agency relationship between you and Xenta.
We will not disclose non-public operation data except as required to operate the service, comply with law, or protect the security and integrity of the platform.
