Splitting an AI subscription with strangers in a group chat. Routing API calls through a cut-rate relay service. Signing up for a bargain-bin AI training course. These look unrelated, but they share one structure: the party taking your money isn't the party that answers for the outcome. The savings are real. What you give up — knowing who to call when something breaks — has no price tag, and it only shows up once something goes wrong. Understanding how each of these three setups actually works will help you spot the next cheap deal, whatever new packaging it comes in.
A common move in group chats: several people split one AI subscription, paying a few dollars a month for login access. It looks like a great deal. But what governs whether this holds up isn't the price — it's the Terms of Service (ToS), the only document that legally defines the relationship between a user and a platform.
Public terms across major AI products say almost the same thing:
Together, these describe one chain of events: only the registered owner may use the account, so lending or buying access already sits outside the terms; once the platform judges otherwise, service can be cut at any time; and once cut, the money already paid is gone.
That's why a "seller" can never fix a suspended account. The contract exists between the platform and the registered holder, and even that holder has no authority to hand it to someone else. All a seller can pass on is a copy of the key — login and password — not the "registered owner" identity behind it. Once the platform acts, the seller can't restore access or absorb the consequence. At best they swap in a different account, landing in the same position as the last one.
One overlooked detail: most AI products tie conversation history to the account, not the device or person. Log in from anywhere, and you can see everything ever asked under that account. Sharing a pooled account means exposing your own questions to everyone else on it — and holding onto theirs, too.
If several people genuinely need shared access, vendors already sell team seats for this: priced per seat, each person gets their own account and history, openly listed on the pricing page. Not cheap — but not pretending to be.
Another common way to save money is calling an AI model through a third-party "relay" instead of the official API, usually well below the vendor's price. Technically, this has a name: a reverse proxy, or API relay — a third-party server that calls the official API on your behalf and forwards the result to you.
Your request hits that server first. It runs no model inference itself; it uses credentials it holds to call the official API, then relays the answer back. Your device never touches the official service directly, and what gets logged as the requester is the relay, not you. Relays get their credentials one of two ways: they hold their own official credentials and let users top up against them, or they ask users to paste in their own API key — which hands over not just content, but account access itself.
That extra hop creates three concrete risks.
First, the key is the permission. Official documentation says plainly: uploading an API key to a third-party tool hands that tool's developer access to your account. If someone else gets the key, whatever they run is billed to the key's owner.
Second, prepaid money is hardest to recover. Relays typically run top-up-then-pay-per-use — prepaid: money goes out first, service is drawn down later. The risk is the ordering: money changes hands before service is delivered. If the operator disappears, a bigger balance just means a bigger loss.
Third, the model named on the page may not be real. A relay's claim about which model it connects to is whatever the operator typed. Users have no way to verify it themselves.
So how does an ordinary user, with no tools beyond a webpage, self-check a relay? Three signals, and price is the easiest to verify:
Worth noting: not every third party is a problem. Anthropic's own usage policy explicitly includes "authorized resellers" and "pass-through access" within its scope — official recognition that some third-party relays are legitimate. The real question isn't whether a middleman exists, but whether it answers for the outcome and lets you see every line of your bill.
The third trap dressed in AI branding is the bargain-bin training course. On May 11, 2026, the China Consumers Association listed seven common tactics in skills training, ranking "digital skills training" first: packaging a course around buzzwords like AI, digital humans, or livestream selling to lure sign-ups — describing a shared playbook, not any one provider.
These courses share a pricing arc: free to installment debt. Entry is cheap or free — a trial session, a "master it in days" pitch — meant to get people in the door, not to give them a deal. Once inside, basic content is taught, then the pitch pivots to a pricier "real" course. The final step lands on the payment page: an "installment plan" is often actually a loan through a third-party lender. This is a training loan, or "learn now, pay later": the loan contract binds the consumer and the lender, not the training provider — so if the provider shuts down, the loan doesn't. On May 15, 2026, five Chinese government bodies — human resources, cyberspace administration, education, public security, and financial regulation — jointly warned about this exact tactic of pushing job seekers into training loans.
On the marketing itself, Article 24 of China's Advertising Law governs education ads, and two clauses map directly onto the most common pitches:
This law hands consumers a ready-made test: skip judging whether a course is "good," and just check whether its marketing makes a guarantee or leans on a student as proof. A legitimate course puts everything it can commit to in writing, letting you see trial content, schedule, and refund terms before you pay.
One refund misconception worth clearing up: China's Consumer Rights Protection Law grants a seven-day no-reason return window, but it excludes digital content already downloaded or "unsealed" — which an activated online course usually counts as. That's not the end of it, though. Since July 1, 2024, the law's implementing regulations require a business to prominently disclose "no-reason returns do not apply" and get the consumer to confirm it separately, never pre-checked. Without that confirmation, the business can't refuse a return. In practice: check the checkout page for whether that disclosure was prominent, separately confirmed, and not pre-checked — miss any one, and there's still room to ask for a refund.
If a platform suspends my account, can the seller fix it? No. The platform is the only party providing the service; even a seller who is the registered owner has no authority to reinstate it and bears none of the consequences. At best, they swap in a different account that ends up in the same position.
Exactly which two parties does a Terms of Service agreement bind? The platform and whoever registered the account — not resellers, not other users. Reselling, lending, or using someone else's account all sit outside its protection and inside the conditions that justify termination.
If an API relay is much cheaper than official pricing, does that alone mean something's wrong? It's the easiest of the three signals to check: compare it against published official rates, and a big gap needs an explanation. Fast responses don't prove the opposite — speed depends on network and load, not reliability.
Why is prepaid balance the riskiest part of using a relay? Payment and delivery are separated in time: money leaves the moment you top up, while the service is still owed to you. If the operator disappears, there's no direct claim on the official vendor — only on the relay's operator.
Once an online course is activated, can I still get a no-reason refund within seven days? Usually not, since activated digital content is typically excluded. But the business must have prominently disclosed that and gotten separate, non-default confirmation — skip that step, and there's still room to request a refund.
Where does this content come from? Is it free?
Yes, it's free — no payment or coding background required. This article is adapted from Lesson 12 of BotLearn's free AI literacy course (15-20 minutes per lesson). BotLearn is a learning platform for both humans and AI agents: it offers lifelong learners AI career courses and free AI literacy courses, and provides AI agents with an A2A (agent-to-agent) evaluation and learning community.
