Terms of Service

Effective: May 14, 2026

These Terms of Service (the "Terms") govern your access to and use of the websites, applications, and services operated by Anthesia LLC, an Ohio limited liability company ("Anthesia," "we," "us," or "our"), including the websites at anthesia.io and any product-specific properties operated under the Anthesia brand (collectively, the "Service").

By accessing or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. About Anthesia

Anthesia operates a portfolio of software products and services, which may include consumer applications, developer APIs, and related offerings. Individual products may have additional terms specific to that product, which will be presented at the time you sign up for or use them. In the event of a conflict between these Terms and product-specific terms, the product-specific terms control with respect to that product.

2. Eligibility

You must be at least 13 years old (or the minimum age of digital consent in your jurisdiction, whichever is higher) to use the Service. If you are using the Service on behalf of an organization, you represent that you are authorized to bind that organization to these Terms.

3. Accounts

Some parts of the Service may require an account. You are responsible for safeguarding your credentials and for any activity that occurs under your account. Notify us promptly at support@anthesia.io if you suspect unauthorized access. We may suspend or terminate accounts at our discretion, including for violation of these Terms.

4. Acceptable use

You agree not to:

  • Use the Service in any unlawful manner or in violation of applicable laws or regulations;
  • Interfere with, disrupt, or attempt to gain unauthorized access to any part of the Service, related systems, or networks;
  • Probe, scan, or test the vulnerability of the Service except as expressly permitted under a coordinated disclosure arrangement with us;
  • Use the Service to send unsolicited communications, distribute malware, or engage in fraud or impersonation;
  • Reverse engineer, decompile, or attempt to extract source code from the Service, except to the extent expressly permitted by law;
  • Resell, sublicense, or commercially exploit the Service except as expressly permitted by these Terms or a separate written agreement with us.

5. API terms

If you access a product offered as an application programming interface (an "API"), the following additional terms apply:

  • Each API key is issued to a single account and may not be shared. You are responsible for activity made using your API keys.
  • You agree to abide by published rate limits and to implement reasonable retry and backoff behavior in your client.
  • You may cache API responses solely to the extent necessary to operate your application and consistent with any cache-control directives we publish. You may not build or distribute a derivative database that materially substitutes for the API itself.
  • If we provide source data attribution requirements, you agree to display them in any user-facing context where the data appears.
  • We may modify, deprecate, or discontinue any API, endpoint, or feature with reasonable notice. For material breaking changes, we will provide at least thirty (30) days' notice via the contact email associated with your account where practicable.

6. Fees and payment

Some products are offered on a paid basis. Fees, billing cycles, and payment terms will be presented at the time you subscribe. Payment is processed by third-party payment processors (currently Stripe), and you agree to be bound by their terms when transacting through them.

Unless stated otherwise, fees are non-refundable, except where required by law. You may cancel a recurring subscription at any time through your account settings or by emailing billing@anthesia.io; cancellation takes effect at the end of the current billing period.

7. Intellectual property

The Service, including all software, designs, text, graphics, and other content produced by us (excluding User Content, defined below), is owned by Anthesia or its licensors and is protected by intellectual property laws. Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for its intended purpose.

"User Content" means any content you submit, upload, or transmit through the Service. You retain ownership of your User Content. By submitting User Content, you grant Anthesia a worldwide, non-exclusive, royalty-free license to host, store, process, and display that content solely as necessary to operate and improve the Service.

8. Third-party services and data

The Service may incorporate or link to third-party services, websites, or data sources, including public datasets such as those published by the U.S. Food and Drug Administration. Third-party services are governed by their own terms, and we are not responsible for them. References to data sources do not imply endorsement by those sources.

9. Disclaimer of warranties

THE SERVICE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANTHESIA DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE.

We do not warrant that the Service will be uninterrupted, secure, error-free, or that data returned by the Service will be complete, accurate, or up to date.

10. Medical and professional disclaimer

Some Anthesia products (including, without limitation, the MedData API) provide information sourced from public data for developer and informational purposes only. Such information is not medical advice and is not a substitute for the diagnosis, advice, or treatment of a qualified healthcare professional. Reliance on any information provided through the Service is solely at your own risk. Always consult a qualified professional regarding any medical question or condition.

11. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, ANTHESIA AND ITS OFFICERS, EMPLOYEES, AND AGENTS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE, WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNTS YOU PAID TO US FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100).

Some jurisdictions do not allow the exclusion or limitation of certain damages; in such jurisdictions, our liability is limited to the maximum extent permitted by law.

12. Indemnification

You agree to indemnify, defend, and hold harmless Anthesia and its officers, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or related to (a) your use of the Service, (b) your User Content, or (c) your violation of these Terms or any applicable law.

13. Termination

You may stop using the Service at any time. We may suspend or terminate your access to the Service, with or without notice, if we reasonably believe you have violated these Terms or if we discontinue the Service. Provisions of these Terms that by their nature should survive termination (including ownership, disclaimers, limitations of liability, and indemnification) will survive.

14. Governing law and dispute resolution

These Terms are governed by the laws of the State of Ohio, without regard to its conflict of law principles. The parties consent to the exclusive jurisdiction of the state and federal courts located in Franklin County, Ohio for any dispute arising out of or related to these Terms or the Service, except that either party may seek injunctive relief in any court of competent jurisdiction.

15. Changes to these Terms

We may revise these Terms from time to time. The "Effective" date at the top of this page indicates when the current version took effect. For material changes, we will provide reasonable notice through the Service or by emailing the address associated with your account. Continued use of the Service after the effective date of any changes constitutes your acceptance of the revised Terms.

16. Miscellaneous

These Terms constitute the entire agreement between you and Anthesia regarding the Service, and supersede any prior agreements. If any provision of these Terms is held to be unenforceable, the remaining provisions will remain in full effect. Our failure to enforce any right or provision is not a waiver of that right or provision. You may not assign these Terms without our prior written consent; we may assign these Terms in connection with a merger, acquisition, or sale of assets.
