These terms govern your use of the CallAI website, API, tools and cloud servers. By creating an account, topping up or calling the service, you agree to these terms, the Privacy Policy and the Acceptable Use Policy.
CallAI (青柠AI, callaiapi.com) is operated by Hanshu Technology (汉书科技, "we"). The "service" means our LLM API, SEO data API and MCP server, website tools, domain checks and cloud servers.
You must be at least 18, or the age of majority where you live. If you use the service for a company, you confirm you may accept these terms on its behalf.
You are responsible for your account and API keys. You are liable for all calls and charges made with your keys, including after a key leaks. If a key leaks, revoke it in the console right away. You can set a spend limit on each key.
You may build the service into your own products, but you may not resell bare API access on its own.
Parts of the service rely on third parties, including model providers, DataForSEO, cloud providers and payment processors. Their outages, limits or changes can affect the service.
We may add, change or remove models and features. Whether a model can be called is shown by the GET /v1/models list and the notice on its model page.
Free tools and allowances may have usage limits, which we can change or withdraw.
The service is pay as you go from a prepaid USD balance, with top-ups from $1 and no monthly fee. Cloud servers are billed monthly; see section 6. Prices are those on the pricing and model pages and in API responses. Price changes only affect later usage.
Your balance does not expire, but it is not cash or a deposit: it earns no interest, cannot be withdrawn and cannot be transferred to another account.
Card and other fiat payments are processed by Dodo Payments as Merchant of Record, whose terms also apply; tax is charged as shown at checkout. USDT payments count once confirmed on-chain. Use the network and address shown on the page, as we cannot recover funds sent to the wrong one.
If you think a charge is wrong, contact us within 30 days of it with the request ID or transaction details.
USDT top-ups: on-chain transfers cannot be reversed, so these cannot be refunded or withdrawn once credited.
Card and other fiat top-ups: these are non-refundable once completed, except where the law requires otherwise. For a duplicate or clearly mistaken charge, contact us within 30 days and we will refund it once verified.
Cloud servers: if provisioning fails or times out, the instance is destroyed and the charge is returned to your balance in full. The current period of a delivered server is not refunded.
Services terminated for breaching the Acceptable Use Policy are not refunded. We may suspend accounts that file a chargeback without good reason.
Nothing here limits consumer rights that cannot be excluded under the law where you live.
Cloud servers are billed in 30-day periods and renew automatically from your balance before they expire. To stop renewal, delete the server in the console before it expires.
If your balance cannot cover renewal, we try to warn you beforehand. A server that expires without renewal is deleted and its data cannot be recovered. Keep your own backups; we are not responsible for data on your server.
Servers run on third-party cloud infrastructure and are also subject to the provider's rules. Licences and security updates of one-click apps are your responsibility.
You must follow the Acceptable Use Policy, applicable law and the usage policies of the model providers you use. You may not use the service to send spam, phish, attack third parties or distribute malware or illegal content, or try to get around limits, billing or security measures.
On a credible abuse report we may suspend the affected service first and contact you afterwards.
As between you and us, what you submit and the output generated for you belong to you, subject to the terms of the model provider concerned. You must have the right to submit that content. The Privacy Policy explains how we handle data.
AI output can be inaccurate or incomplete, and can resemble output others receive. Check it before relying on it, especially for legal, medical, financial or other important uses.
SEO data comes from third parties. Metrics such as search volume, traffic and difficulty are estimates and can be wrong or out of date. We do not promise any ranking, traffic or revenue result.
A domain check verdict reflects only the sources checked. It is for reference and does not guarantee a domain has no other history problems. Buying a domain is your decision and your risk. Use data in line with its source's rules and applicable law.
We or the relevant owners hold the rights in the website, software and branding. These terms grant no rights beyond the use they allow. Third-party names and trademarks on our pages belong to their owners.
To the fullest extent the law allows, the service is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, or uninterrupted or error-free operation.
To the fullest extent the law allows, we are not liable for indirect, incidental, special or consequential losses, including lost profits, revenue, data or goodwill.
Our total liability for the service will not exceed what you paid us in the 12 months before the event giving rise to the claim. Liability that the law does not allow us to exclude or limit is unaffected.
If a third party makes a claim against us because of your breach of these terms, your breach of the law or the content you submit, you will cover our resulting losses and reasonable costs. This does not apply where the law where you live does not allow it for consumers.
You can stop using the service at any time and request account deletion by support ticket. Any remaining balance is not refunded when an account is deleted, except where the law requires otherwise.
We may suspend or terminate your account if you breach these terms, or where law or security requires it. If we decide to stop offering the whole service, we will give at least 30 days' notice so you can use your balance and move your data.
Sections 8 to 13 and section 15 survive termination.
We may update these terms and will change the effective date above. Material changes are announced on the site at least 14 days ahead. Continuing to use the service after they take effect means you accept them; if you do not, stop using the service.
If a dispute arises, contact us first and we will reply within 30 days. If that does not settle it, the law of the place where the operator is registered applies, and its competent courts handle the dispute. Mandatory consumer protection law where you live is unaffected.
If any term is held invalid, the rest remain in effect. Not exercising a right does not waive it. If the Chinese and English versions conflict, the English version prevails.
