Terms of Service
Last updated: March 2026
Acceptable Use
You may use the Hesper AI API only for lawful purposes and in accordance with these Terms. You agree not to use the Service to analyze documents you do not have the right to process; to attempt to reverse-engineer, circumvent, or interfere with the Service; to submit documents containing personal data without appropriate consent or legal basis; to use the Service in any manner that violates applicable law or regulation; or to resell or sublicense the Service without express written permission. We reserve the right to suspend or terminate access for violations of these terms.
API Access
Access to the Hesper AI API is granted subject to these Terms and the plan you have selected. Your API key is personal to your account and must not be shared. You are responsible for all usage associated with your API key. Rate limits and volume limits apply as specified in your plan. We reserve the right to modify API endpoints, response formats, and features with reasonable notice. Breaking changes will be communicated with at least 30 days advance notice on the Enterprise plan.
Limitations of Liability
The Service is provided "as is" and "as available." While we strive for high accuracy, Hesper AI does not guarantee that fraud will be detected in all cases, nor that clean documents will always be returned without a fraud flag. The Service is designed to assist human review, not replace it. We will not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the Service. Our total liability for any claim arising from these Terms shall not exceed the fees paid by you in the 12 months preceding the claim.
Intellectual Property
Hesper AI retains all intellectual property rights in the Service, including the API, detection models, and documentation. You retain all intellectual property rights in the documents you submit. By using the Service, you grant Hesper AI a limited license to process your documents solely for the purpose of providing the fraud detection service. We do not claim ownership of your documents, and we do not use your documents to train our models or for any purpose beyond providing the analysis service.
Termination
Either party may terminate this agreement at any time with 30 days written notice. We may terminate immediately if you breach these Terms, fail to pay fees when due, or if we are required to do so by law. Upon termination, your access to the API will be revoked and any outstanding fees will become immediately due. Sections relating to intellectual property, limitation of liability, and governing law will survive termination.
Governing Law
These Terms are governed by the laws of England and Wales. Any disputes arising from these Terms or your use of the Service shall be subject to the exclusive jurisdiction of the courts of England and Wales. If any provision of these Terms is found to be unenforceable, the remaining provisions will continue in full force and effect.
