1. Why this document exists
1.1 This statement forms part of the Terms of Service and is referred to by section 9 of them. It is written separately because it is the single most important thing to understand about how PowerHub works.
1.2 PowerHub funds and meters AI access. It does not produce AI. Every model you can reach through us is built, hosted, priced and operated by another company. We are a customer of those companies, the same as you would be if you signed up directly, and we pass what we buy through to a campaign's key.
2. Who the providers are
2.1 The table below is generated from the provider packages the endpoint actually serves, so it is always the current list rather than a description of one:
Verified on 11 September 2026.
2.2 This list changes. Providers are added when we can support them and removed when we cannot. Because the table is generated, it changes with them on the day they change. It states who serves requests today, and it is not a commitment that any of them will still be there tomorrow (section 5).
2.3 Some providers have no HTTP interface we can meter. For those, access is arranged by hand as a grant. Everything in this document applies to them too.
3. Their rules apply to you
3.1 By sending a request through PowerHub you agree to the terms and policies of the provider whose model answers it, as they apply to that request. We cannot waive them, soften them or grant you anything they withhold.
3.2 In practice this means at least the following, and you agree to each of them as a term of using PowerHub. The providers named in these bullets are examples, quoted because their wording is the clearest: they are not the list of providers, and a clause quoted here is not the whole of any provider's policy. The current list, and the link to each policy in force, is the generated table in section 2.
- You are 18 or over. Google's Gemini API terms state: "You must be 18 years of age or older to use the APIs." This is why PowerHub is an adults-only service (Terms, section 3.1).
- You will not build an application aimed at, or likely to be used by, people under 18 through access obtained on PowerHub, unless the relevant provider has approved that use in writing and you have told us.
- You follow every prohibited-use policy of the provider you are using. Anthropic's policy alone forbids illegal activity, compromising critical infrastructure or computer systems, weapons development, incitement to violence or hate, violations of privacy and identity rights, harm to children's safety, psychologically harmful content, misinformation, interference with democratic processes, prohibited surveillance and law-enforcement uses, fraudulent and predatory practices, platform abuse, and sexually explicit content. The other providers publish comparable lists. Section 12 of our Terms restates them; where they differ, the stricter rule applies.
- You disclose AI where the provider requires it. Anthropic's policy requires that "all consumer-facing chatbots... must disclose to users that they are interacting with AI rather than a human", and that high-risk advice reviewed for consumers is marked as AI-produced and reviewed by a qualified professional. If you deploy something built on PowerHub access to other people, that duty is yours.
- You do not resell, sublicense or transfer access. OpenAI's services agreement prohibits buying, selling or transferring API keys and prohibits reselling or leasing access to an account. Anthropic's commercial terms permit a customer to use the services "to power products and services Customer makes available to its own customers and end users" but prohibit reselling the services "except as expressly approved by Anthropic". This is exactly why PowerHub issues you a PowerHub key to a PowerHub endpoint instead of handing you a provider's key: the provider's account is ours, the integration is ours, and you are its end user. Do not undo that by passing your PowerHub key to somebody else.
- You accept the provider's rate limits. When a provider limits us, we forward its refusal to you unchanged, with its
retry-afterheader, and we charge you nothing for the refused request. - You accept the provider's data handling. What a provider does with a request (how long it retains it, whether it is reviewed for abuse, what it trains on) is set by that provider's terms and its data processing agreement with us, not by us. We make no representation about it (Terms, section 16.3).
3.3 A provider may require something not listed here, or change what it requires. Read the linked policies. Following them is your obligation, not ours.
4. What we do and do not check
4.1 We meter money. Before a request is forwarded we reserve its worst-case cost; after the provider answers we charge the actual cost. That is the whole of our involvement in the content of a request.
4.2 We do not read your prompts and we do not keep them. We forward the request byte for byte and stream the answer back. We keep only the metering facts listed in the Privacy policy, section 5. We therefore cannot pre-screen what you send, and nothing in this document should be read as a promise that we do.
4.3 The consequence is section 6 of our Terms: what you generate is yours, and it is your responsibility.
5. Availability, changes and withdrawal
5.1 We give no guarantee that any provider or model is available, or stays available. Access is offered on an "as available" basis and nothing more.
5.2 A provider may, at any time and without asking us:
- take a model out of service, deprecate it, or replace it with one that behaves differently;
- change its prices, in either direction;
- change its terms, its usage policy or its data handling;
- add a restriction, a region block, a rate limit or an approval requirement;
- refuse an individual request, or a category of requests;
- suspend or terminate our account, or leave the market entirely.
5.3 None of that is a breach of our terms by us, and none of it entitles you to a refund, a credit, an extension or compensation from us. This mirrors what every comparable service says. OpenRouter's terms state that it "disclaims all liability for any suspension, restriction, disabling, termination, removal, unavailability, degradation or modification of any Model arising from or related to Model Terms of the acts or omissions of any Model Provider". Vercel's terms allow it to cease providing third-party services "without entitling you to any refund, credit or other compensation, if... a Non-Vercel Services provider ceases to make the Non-Vercel Services available". Cloudflare's terms state that it "does not control and has no liability for Third-Party Products". Our position is the same.
5.4 What happens to the money when a provider goes away. Your campaign's balance is not held at the provider. It is cash in our ledger, and it moves to a provider only as that provider actually serves a request. So a provider's withdrawal does not destroy a balance. The creator asks for a different provider or model through the model-request form, an operator answers, and the balance is pointed at what is still available.
5.5 What does not happen. A balance is never converted to cash and never paid out to a creator, on any event, including a provider's withdrawal (Terms, section 8.3). If no provider we support can serve a campaign at all, we will say so and an operator may return the unspent balance to backers' wallets pro rata (Refund policy, section 9.2).
5.6 We may pause a provider or a single model for everyone at short notice: during a provider incident, after an unverified price change, or where we suspect abuse. A pause does not consume a balance.
6. Price changes
6.1 Requests are charged at the provider's published price for the model used, with no markup from us. We refresh those prices from the providers.
6.2 If a provider raises a price, a campaign's balance buys less. That is not a change to our fees and it does not create a claim against us. If a provider lowers a price, the balance buys more.
6.3 If we cannot verify a provider's current price for a model, we pause that model rather than guess.
7. Liability
7.1 Sections 16 to 18 of the Terms of Service apply in full to everything in this document. In particular, we are not liable for any act or omission of an AI provider, and our total liability to you is capped as set out in Terms, section 17.2.
8. Contact
8.1 Questions about a provider, a model, a price or a request: legal@powerhub.dev. If your question is about how a provider handles data or what its policy permits, the provider's own documentation is the authority and we will point you at it.
