Terms of Service

Effective: February 27, 2026

These Terms of Service (“Terms”) govern your access to and use of the Guardian Engine API and related services (“Service”) provided by Kaimei Labs (“we”, “us”, or “our”). By using the Service, you agree to these Terms. You must be at least 18 years old or the age of legal majority in your jurisdiction to use this Service.

1. Service Description

Guardian Engine is a deterministic recipe verification engine. It accepts candidate recipes as structured JSON and returns a verification report comparing the candidate against curated master recipes. The Service is made available via a publicly accessible MCP (Model Context Protocol) endpoint and REST API.

2. Acceptable Use

You may use the Service for:

Verifying AI-generated or user-submitted recipes against our master recipe database.
Integrating verification into your AI agents, applications, or platforms.
Research, evaluation, and educational purposes.

You may not:

Attempt to extract, reverse-engineer, or reconstruct our master recipe dataset.
Submit excessively large or malicious payloads designed to degrade the Service.
Resell raw verification results as a standalone competing product.
Use the Service in any way that violates applicable laws or regulations.

3. Early Access & Fair Use

The Service is currently in an early-access period and is provided free of charge under fair-use terms. We enforce compute-level quotas via automated infrastructure limits and rate limiting. We reserve the right to throttle or block traffic that exceeds reasonable usage patterns.

We will provide at least 30 days’ notice before transitioning to paid access or materially changing the terms of the early-access period.

4. Data, Privacy & Usage Rights

No PII collected — we do not store user names, email addresses, or API keys in our application logs. Underlying cloud infrastructure may temporarily process IP addresses for security and routing purposes. You agree not to include personally identifiable information (PII) within recipe payloads.
Data for Compute Exchange — The free early-access Service is provided in exchange for usage data. By submitting candidate recipes, you grant Kaimei Labs a perpetual, irrevocable, worldwide, royalty-free license to use, store, modify, aggregate, distribute, and sublicense the submitted content to train our models, improve the Service, and create derived datasets.
Anonymization — We will not publish or share your raw submitted recipes with third parties in a way that identifies you or your application. Any external datafeeds or datasets we produce will be anonymized, aggregated, or transformed into Reinforcement Learning (RL) feedback data.

5. Intellectual Property & Derived Data

Your Content: You retain all intellectual property rights to your original candidate recipes and application code.
Our Engine: The Guardian Engine source code, master recipes, knowledge base, and public SDKs (unless otherwise licensed via MIT) remain the sole property of Kaimei Labs.
Derived Data: Kaimei Labs owns all rights, title, and interest in and to any telemetry, metadata, verification reports, and aggregated or derived datasets (including RLDF datafeeds) generated by your use of the Service.

6. Disclaimer of Warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not guarantee that the Service will be uninterrupted, error-free, or that verification results are suitable for any particular purpose.

Verification results, including any safety-related findings (such as cooking temperature or allergen warnings), are automated and informational only. They should not be relied upon as professional food safety, health, or culinary advice.

7. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, KAIMEI LABS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING FROM YOUR USE OF THE SERVICE, INCLUDING BUT NOT LIMITED TO DAMAGES FOR LOSS OF PROFITS, DATA, OR GOODWILL.

In no event shall our total aggregate liability to you for all claims arising out of or relating to these Terms exceed fifty euros (€50) or the total amount you paid us to use the Service in the preceding 12 months, whichever is greater.

8. Indemnification

You agree to indemnify, defend, and hold harmless Kaimei Labs, its officers, directors, and agents from any claims, damages, losses, liabilities, and expenses (including reasonable legal fees) arising out of or related to your use of the Service, your violation of these Terms, or any third-party claims resulting from your integration of the Service into your products or applications.

9. Termination

We reserve the right to suspend or terminate your access to the Service at our sole discretion, without prior notice, for conduct that we determine violates these Terms or is harmful to the Service, other users, or third parties.

10. Governing Law

These Terms are governed by and construed in accordance with the laws of the Netherlands, without regard to its conflict-of-law provisions. Any disputes arising from or relating to these Terms or the Service shall be subject to the exclusive jurisdiction of the competent courts of the Netherlands.

11. Changes to Terms

We may update these Terms at any time. Material changes will be communicated via this page and, where possible, through our developer documentation. Continued use of the Service after changes are posted constitutes acceptance of the updated Terms.
