Terms of Service

1. Who we are and what these terms cover

zzo.ai ("zzo.ai", "we", "us") lets you generate videos and images with third-party AI models and pay per generation with credits. zzo.ai is run by an independent developer. These Terms of Service apply to the website, the API and the MCP integration (together, the "Service"). By creating an account or using the Service you agree to these terms, our Acceptable Use Policy, our Privacy Policy and our Refund Policy. If you do not agree, do not use the Service.

2. Eligibility and accounts

You must be at least 18 years old, or the age of majority where you live if that is higher, to use the Service.

The Service is not offered in mainland China, Hong Kong or Macau. Several of the models it provides are not available there under their providers' own terms, and the Service has not completed the filings that would be required to offer generative AI services to the public in mainland China. Do not use the Service from those places.

You are responsible for keeping your sign-in details and API keys secret and for everything done through your account. Tell us at hi@zzo.ai if you think your account or a key has been used without your permission.

3. Credits and payments

• Generations are paid for with credits. You buy credits in one-time packs; there is no subscription and nothing renews automatically.
• The number of credits a generation costs is shown before you start it. Prices for each model can change; a change never affects a generation that has already started.
• Credits never expire. They stay in your account until you use them.
• Credits have no cash value, cannot be transferred to another account and cannot be exchanged for money, except through a refund under the Refund Policy.
• Credits are non-refundable once used. A pack can be refunded only as described in the Refund Policy. At checkout you confirm that you understand this.
• If a generation fails, times out, is rejected by an upstream model's content filter, or its result is blocked by our content checks, the credits it used are returned to your balance automatically. These returns are made in credits, not money. A request blocked by our content checks before it runs costs nothing.
• Payments are processed by our payment provider. You agree to its terms when you pay.

4. Your inputs and your responsibility

"Inputs" are the prompts, images and other material you submit. "Outputs" are the videos and images the Service generates for you.

• You must own your inputs or have every right and permission needed to use them with the Service.
• Do not upload a photo of another person without their consent. You may upload a photo of yourself, or of someone who has agreed to it.
• Do not upload photos of public figures or celebrities, and do not try to generate their likeness, whether or not you have their consent.
• You are responsible for how you use outputs, including where you publish them and whether that use is lawful. Check outputs before you rely on them; AI models can produce inaccurate, unexpected or unsuitable results.
• Subject to these terms and the rights of others, you may use your outputs for any lawful purpose, including commercial use. We do not claim ownership of your inputs or outputs. Similar outputs may be generated for other users, and we cannot promise that an output is unique or protected by copyright.

5. Prohibited content and conduct

The Acceptable Use Policy sets out in detail what is not allowed and how it is enforced. In short, you must not use the Service to create, upload or share:

• Sexual content involving minors, or any content that sexualizes minors. We report such content to the relevant authorities.
• Pornography, nudity or other sexually explicit content.
• Graphic violence or gore, or content that encourages self-harm.
• Non-consensual intimate imagery, including sexual or nude depictions of a real person made without their consent.
• Content meant to deceive or impersonate, such as fake footage presented as real events, or content that passes itself off as a real person or organization.
• Harassment, threats, bullying, or content that targets a private individual.
• Content that promotes violence or hatred against people based on a protected characteristic.
• Content that infringes someone else's copyright, trademark, privacy or publicity rights.
• Anything else that is illegal where you live or where it is published.

You also must not try to get around content filters, usage limits or security measures, resell access to the Service without our written agreement, use automated means to create accounts, or interfere with the Service or other users.

We check prompts, uploaded images and results automatically before a generation runs and before a result is shown, and record every block. After repeated blocks, generation is paused on the account for up to 24 hours. Upstream model providers also apply their own content filters and may refuse a request. In either case, credits are returned or not charged as described in section 3. To report abuse or appeal a block, email hi@zzo.ai.

6. Third-party model providers

Generations run on models from third parties, accessed through official API channels such as fal.ai and EvoLink. Their availability, features, output quality and prices are outside our control and can change. We may add, change, replace or remove models, change the credit price of a model, or pause a model when a provider is unavailable. We will show the current price before every generation.

7. API and MCP access

You can create API keys in your account settings to use the Service from your own code or from MCP clients. API and MCP use draws on the same credit balance and prices as the website. We apply a per-request credit limit and a daily credit limit to API and MCP use, and may change these limits to protect your balance and the Service. Keep your keys secret; you are responsible for all usage made with them. We may revoke a key that is leaked or misused.

8. Suspension and termination

We may suspend or close your account, revoke API keys, or remove content if you break these terms, if we reasonably suspect abuse, fraud or payment disputes made in bad faith, or if the law requires it. Where we close an account for abuse, unused credits may be forfeited. You can stop using the Service at any time and ask us to delete your account by writing to hi@zzo.ai.

9. Disclaimers and limitation of liability

The Service is provided "as is" and "as available". We do not promise that it will be uninterrupted or without errors, or that any model will stay available. To the extent the law allows, our total liability for any claim relating to the Service is limited to the amount you paid us in the twelve months before the claim. Nothing in these terms limits liability that cannot be limited by law, or your statutory rights as a consumer.

10. Indemnity

You agree to cover our reasonable losses and costs arising from your inputs, your use of outputs, or your breach of these terms, to the extent the law allows.

11. Changes to these terms

We may update these terms. We will post the new version here with a new date and, for significant changes, tell you by email or on the site. Continuing to use the Service after a change means you accept the updated terms.

12. Governing law

These terms are governed by the laws of the State of Delaware, United States, without regard to its conflict-of-law rules. Any dispute arising from these terms or the Service will be heard by the state or federal courts located in Delaware, and you and we agree to their jurisdiction.

If you are a consumer, this section does not take away any protection you have under the mandatory laws of the country where you live, including any right to bring a claim in your local courts.
