Terms of Service

Last updated: 10 November 2026 · Effective immediately · Quanta
Short version: You buy prepaid credits to call third-party AI models. We pass through model prices and charge a one-time fee when you buy credits. Output is AI-generated and may be wrong. Don't use the service for illegal or harmful content. Unused credits can be refunded within 24 hours.

1. Who we are and what this service is

Quanta ("we", "us") provides an API gateway that relays your requests to third-party large language model providers and returns their responses. We are an independent technical service. We are not affiliated with, endorsed by, or an official reseller of OpenAI, Anthropic, DeepSeek, Alibaba, Moonshot AI, Zhipu, Meta, Mistral, or any other model provider. Model names are used solely to identify the underlying model.

We disclose the actual underlying model and provider for every entry in our model catalog. All content produced through the service is generated by artificial intelligence and is labeled as such in the product interface.

2. Credits and pricing

Credits are a prepaid, non-transferable digital service balance denominated in USD. They are not currency, a stored-value instrument, a security, or property redeemable for cash except under the refund policy below.

3. Payment, taxes and Merchant of Record

Payments are collected and processed by our payment partner acting as Merchant of Record (MoR). The MoR is the legal seller of record, calculates and remits applicable sales tax, VAT and GST, issues invoices, and handles chargebacks and disputes. We receive a net settlement and remain responsible for delivering the service and for product-level support.

You authorize the charge shown at checkout. All prices are in USD unless stated otherwise. You are responsible for any taxes or reporting obligations in your own jurisdiction that are not handled by the MoR.

4. Refunds and cancellation

You may request a refund of unused credits within 24 hours of purchase by contacting support. Platform fees, payment processing fees and credits already consumed are non-refundable. Cryptocurrency payments, where offered, are never refundable.

There is no recurring subscription and nothing to cancel. Refunds, when granted, are returned to the original payment method by the MoR. Chargebacks filed without first contacting support may result in account suspension.

5. Acceptable use

Use of the service is governed by our Acceptable Use Policy, which forms part of these Terms. In summary, you must not use the service to create illegal, sexually explicit, violently graphic, hateful, child-unsafe, deceptive or rights-infringing content, nor to impersonate a real person without authorization. We operate automated and manual content screening, retain records of enforcement actions, and provide a public reporting channel.

Violations may result in immediate rate limiting, content removal, suspension or termination without refund of consumed credits.

6. Your content and data

You retain ownership of prompts you submit and outputs you receive, subject to the model provider's own terms. Prompts are transmitted to the relevant model provider to generate a response. We do not use your prompts or outputs to train models and do not sell them. See our Privacy Policy for retention periods, subprocessors and your rights.

You are responsible for having the rights to any content you submit and for reviewing AI-generated output before relying on it. Model output can be inaccurate, incomplete or offensive.

7. Availability and third-party services

The service depends on third-party model providers and payment processors. We do not guarantee uninterrupted availability, specific model versions, or response times, and may add, change or remove models. We are not liable for a provider's outage, policy change, or discontinuation of a model.

8. Limitation of liability

To the maximum extent permitted by law, our aggregate liability arising from the service is limited to the amount you paid for credits in the twelve months preceding the claim. We are not liable for indirect, incidental, special or consequential damages, or for lost profits, data or goodwill.

9. Accounts and termination

You must provide accurate registration information and keep your API keys confidential. You are responsible for all activity under your keys. We may suspend or terminate accounts for violations of these Terms, for fraud, or where required by law or by a provider's terms.

10. Changes and governing law

We may update these Terms and will post the revised version with a new "Last updated" date. Continued use after that date constitutes acceptance. These Terms are governed by the laws of the jurisdiction of the operating entity, without regard to conflict-of-laws rules.
