Terms of Service
Last updated: 25 August 2026
These Terms of Service (the "Terms") govern your access to and use of the API Stock platform, website and API (together, the "Service"), operated by API Stock ("we", "us"). By accessing or continuing to use the website, creating an account, generating an API key or sending a request to the API, you agree to these Terms, including the analytics collection described in our Privacy and Cookie Policies. If you are entering into these Terms on behalf of a company, you confirm that you are authorised to bind it.
1. What the Service is
API Stock is an aggregator. We expose generation models operated by third parties — for video, image, audio and text — behind a single API, a single API key and a single prepaid balance. We are not the developer of those models: we route your request to an upstream provider, download the result to our storage and return it to you.
- The catalogue of available models changes. We may add, replace, reprice, deprecate or remove any model at any time, including because an upstream provider changed or withdrew it.
- A request may be served by any provider we have configured for that model. If the primary provider fails, we automatically retry the same generation on a reserve provider.
- Nothing in the Service is a guarantee that a particular model, provider, latency or output quality will remain available.
- We use Google Analytics to understand traffic, page usage and the product funnel. By accessing or continuing to use the website, you consent to the analytics collection described in our Privacy and Cookie Policies. If you do not agree, do not continue using the website and block or remove analytics cookies using your browser settings.
2. Eligibility and accounts
You must be at least 18 years old, or the age of majority in your jurisdiction, and legally able to enter into a contract. You must provide accurate registration details and keep them current.
- You are responsible for everything that happens under your account, including usage and charges incurred by anyone you give access to.
- One person or entity per account. Creating multiple accounts to obtain repeated introductory balance or to evade a suspension is a breach of these Terms.
- You must notify us promptly if you believe your account or an API key has been compromised.
3. API keys
API keys authenticate requests to the API and are equivalent to your password.
- Keep keys secret. Do not embed them in client-side code, public repositories or distributed applications.
- You can create, deactivate, regenerate and delete keys from the dashboard at any time. Deactivating or deleting a key stops it working.
- All usage authenticated by a valid key is charged to your balance and is treated as authorised by you, including usage by a third party who obtained your key.
- We may revoke a key without notice if we reasonably believe it has leaked or is being used to breach these Terms.
4. Prepaid balance, pricing and charging
The Service is strictly prepaid. Your balance is denominated in US dollars and is drawn down as you use the Service; there is no invoicing, subscription or credit line.
- The price of each model is published in the catalogue and on that model's page, and is the price applied at the time your request is accepted. Prices may change; a change never applies retroactively to a request already accepted.
- Media generations are charged per generation. Chat (LLM) requests are charged per token consumed, based on the usage reported by the upstream provider.
- A request is priced and the amount is debited before it is dispatched. If your balance is insufficient, the request is rejected and nothing is charged.
- If a generation ultimately fails — including after all retries on reserve providers — the amount charged for it is refunded to your balance automatically. A generation that completes successfully is charged even if you are not satisfied with the output.
- Balance is a prepayment for the Service. It is not a deposit, not e-money, earns no interest, and cannot be transferred between accounts or withdrawn as cash.
5. Top-ups and refunds
You can top up your balance with a fixed pack or a custom amount, within the minimum and maximum shown at checkout. Payments are processed by our acquiring partners; we never receive or store your card details or wallet credentials.
- Crypto payments are credited once the transaction is confirmed by the payment network. Card payments are credited once the acquirer confirms settlement. Confirmation can take longer than the redirect back to the dashboard.
- Bonus amounts granted on top of a paid pack are promotional and are not refundable in cash.
- You may request a refund of an unused balance within 30 days of the top-up that funded it, less any amount already spent and any non-refundable promotional bonus. Refunds are returned to the original payment method where the acquirer supports it.
- We do not refund balance that has already been spent on successfully completed generations.
- If we terminate your account for a breach of these Terms, any remaining balance may be forfeited.
- A crypto payment sent for an amount other than the invoiced one, or after the invoice expired, may not be credited automatically. Contact support with the transaction reference.
6. Upstream model providers
Each model is operated by a third party under its own terms and content policy. By using a model through the Service you also accept the terms of the provider serving it.
- We pass your request to the provider, including your prompt and any media you reference. Do not send content through a model that you are not permitted to disclose to a third-party processor.
- If a provider rejects a request under its content policy, that rejection is final. We do not retry such a request on another provider and, since no generation is produced, the amount charged is refunded.
- We are not responsible for a provider's availability, output, moderation decisions, or changes to its own terms.
- Providers may be designated third-party beneficiaries of this section.
7. Your content, and the output
"Input" means the prompts, parameters, images, audio and other material you send. "Output" means what a model returns for your request.
- You keep all rights you already have in your Input. You represent that you own or are licensed to use it, and that sending it to us and to the relevant provider does not infringe anyone's rights.
- You grant us a limited licence to host, transmit, process and store your Input and Output solely to operate the Service — routing the request, producing and delivering the result, billing it, and supporting you. We do not use your Input or Output to train models.
- As between you and us, you own the Output, to the extent it is capable of being owned. Model output may not be protectable by copyright in some jurisdictions, and identical or similar output may be generated for other users.
- Output is not verified by us. It may be inaccurate, offensive, or resemble existing works. You are responsible for reviewing it before use and for the consequences of using it.
- Generated media is stored on our storage for a limited retention period, shown in the usage log, and is deleted afterwards. Download anything you need to keep.
8. Acceptable use
You may not use the Service, and may not permit anyone else to use it, to:
- break any law, or infringe any intellectual property, privacy or publicity right;
- generate sexual content involving minors, or any content that sexualises a minor, in any form;
- create non-consensual intimate imagery, or a likeness, voice or persona of a real person for deception, harassment, defamation or fraud;
- produce disinformation, impersonate a person or organisation, or generate material for scams, phishing or malware;
- generate content that incites violence or hatred against a person or group;
- circumvent, disable or probe our rate limits, quotas, billing or authentication, or the equivalent controls of an upstream provider;
- resell, sublicense or expose the Service as a competing aggregator, or use it to build a substantially similar service;
- scrape the Service, or use it in a way that degrades it for other users.
9. Rate limits, quotas and fair use
The API is rate limited. We may apply, change or tighten limits per account or per key to protect the Service and to comply with the limits our providers impose on us. Sustained use that materially degrades the Service for others may be throttled or suspended.
10. Availability, support and no SLA
We aim to keep the Service available and to fail over automatically between providers, but the Service is provided without any committed uptime, latency or throughput unless we have agreed one with you separately in writing. Maintenance, provider outages and network conditions can interrupt it.
11. Suspension and termination
You may stop using the Service and delete your account at any time.
- We may suspend or terminate your access, with or without notice, if you breach these Terms, if we are required to by law or by an upstream provider, or if we reasonably suspect fraud or abuse of the payment or balance system.
- Where the breach is minor and curable we will normally warn you first.
- On termination your API keys stop working. Sections that by their nature should survive — payment obligations, licences granted, disclaimers, liability limits, indemnity and governing law — survive.
12. Changes
We may change the Service and these Terms. We will publish the updated Terms with a new effective date and, for changes that materially reduce your rights, give reasonable advance notice by email or in the dashboard. Continuing to use the Service after a change takes effect means you accept it. If you do not accept it, stop using the Service and request a refund of your unused balance under section 5.
13. Disclaimers
To the fullest extent permitted by law, the Service is provided "as is" and "as available", without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, accuracy or uninterrupted operation. We do not warrant that Output will be accurate, lawful, original, or fit for any particular use. The Service is not designed for, and must not be relied on in, medical, legal, financial, safety-critical or other high-risk decision-making without independent human review.
14. Limitation of liability
To the fullest extent permitted by law: we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data, goodwill or business opportunity, however caused. Our total aggregate liability arising out of or relating to the Service is limited to the greater of (a) the amount you paid us in the twelve months before the event giving rise to the claim and (b) US$100. Nothing in these Terms excludes liability that cannot lawfully be excluded, including for fraud, or for death or personal injury caused by negligence.
15. Indemnity
You will defend, indemnify and hold us and our affiliates harmless against any claim, loss, liability and reasonable legal cost arising from your Input, your use of the Output, your breach of these Terms or of an upstream provider's terms, or your infringement of a third party's rights.
16. Confidentiality and feedback
Each party will protect the other's non-public information disclosed in connection with the Service and use it only for that purpose. If you send us feedback or suggestions, you grant us a perpetual, irrevocable, royalty-free licence to use them without obligation to you.
17. General
- These Terms, together with the Privacy Policy, are the entire agreement between us about the Service.
- You may not assign these Terms without our written consent. We may assign them to an affiliate or in connection with a merger, acquisition or sale of assets.
- If any provision is held unenforceable, the rest remains in force.
- Our failure to enforce a provision is not a waiver of it.
- We are not liable for a failure to perform caused by events beyond our reasonable control.
- You consent to receiving notices from us electronically, at the email address on your account.
18. Governing law and disputes
These Terms are governed by the law of the place where we are established and by the applicable international rules on cross-border commerce. Before starting proceedings, raise the dispute with us by email at [email protected]; both parties will then try in good faith to settle it within 30 days. Either party may seek injunctive relief in any competent court to protect its intellectual property. Where you deal with us as a consumer, nothing here deprives you of the protection of the mandatory rules of your country of residence or of your right to bring proceedings in its courts.
