Pay-per-call AI. No compromises.
We built Sats4AI because every other AI service wants your identity, your card, and a monthly commitment for tools you use once a week. That trade is a choice — not a requirement.
Why we built this
The identity tax on AI is optional.
Every major AI product sits behind the same wall: email, phone number, card on file, terms of service that change overnight, and a $20/month minimum to keep the lights on. For a journalist in Lagos, a builder in Buenos Aires, or an autonomous agent running on someone's laptop, that wall is the product — not the AI behind it.
Bitcoin Lightning made it possible to charge a tenth of a cent for a single API call, route it across the world in under a second, and settle it without a bank in the middle. The L402 protocol made it possible to turn HTTP 402 — the “Payment Required” status code that sat unused for twenty years — into a real authentication scheme.
Put those two together and the subscription model stops being inevitable. You don't need an account to pay. You don't need an account to be paid. The transaction is the relationship.
What we believe
Privacy, sovereignty, and micropayments are the same idea in three forms.
Privacy is a default, not a feature
We don't collect what we don't need. When there's no account, there's nothing to leak, subpoena, or sell. That's the architecture, not a promise.
You should own your wallet
Not a balance inside our service. Not credits. Not a stored card. You pay an invoice from whatever wallet you already have — we never hold your money.
Agents are first-class users
An AI agent cannot fill out a credit card form, click a CAPTCHA, or sign up for Stripe. L402 and MCP let them pay and work the same way humans do. We designed for agents first.
Micropayments make new things possible
When a phone call costs 40 sats, a translation costs 1 sat per 1000 characters, and a TTS job costs less than a rounded penny, whole categories of software become economically viable for the first time.
How we're built
Self-funded. No investors. Our only obligation is to the person paying the invoice.
Sats4AI is self-funded and independently operated. We have no venture capital, no board, and no growth targets imposed by outside capital. That independence means we don't have a roadmap to monetize user data, bolt on KYC to satisfy an acquirer, or chase vanity metrics.
If we ever have to choose between serving our users and serving someone else, there is no one else to serve. Revenue comes from sats paid by people and agents who find our tools useful. If that stops, we stop.
What this means in practice
- We will never add a signup wall to existing tools.
- We will never require KYC to use a paid endpoint.
- We will never sell usage data, because we don't collect it.
- We will never lock paid results behind a monthly subscription.
- If we shut down, everything you've already paid for you already have. No account state to lose.
How we make money
A small markup on each call. That's the entire business model.
We pay upstream providers for compute, bandwidth, and network services. We add a margin. You pay the total in sats. When a call costs us 3 sats, we charge 5. When a call costs us 1,000 sats, we charge 1,200. No subscription floor, no volume lock-in, no “enterprise” tier that locks features behind a sales call.
Prices in sats generally go down over time. Bitcoin's purchasing power tends upward and models get cheaper — we pass both savings on rather than re-pegging to fiat. See Bitcoin-Native Pricing in the Terms for the full explanation.
What we don't do
Name what you refuse to do, so you can be held to it.
No signup
There is no account to create. There is no login page.
No KYC
We do not verify your identity. We do not know who you are.
No card on file
We do not hold your card. We do not auto-charge.
No data retention
We do not store prompts, files, or generated results beyond the delivery window.
No tracking
We do not build user profiles across requests.
No geo-blocking
Every country. Tor and VPN welcome.
No rate limits on paid calls
Pay per call. Use as much as you pay for.
No lock-in
The L402 protocol is open. The MCP server is public. Walk away any time.
Who we are
Bitcoiners who build infrastructure.
A small team of founders, engineers, and bitcoiners operating Sats4AI full-time. We run our own Lightning nodes, write our own payment code, and rely as little as possible on intermediaries we can't replace. If an upstream provider fails or changes terms, we have a fallback ready. Reliability is a feature you pay for — so we treat it that way.
We're reachable via our contact page, on Nostr, and at events across the Bitcoin circuit. Feedback shapes the roadmap — you can see what's next and vote with sats on the roadmap page.
Get started
The only thing between you and the tools is a Lightning invoice.
