Why bitcoinrouter.ai

  • Anonymous, no KYC

    Just a password. No email, card or ID.

  • No leftovers

    Pause your account and the unspent part goes back to your wallet.

  • We can't read your prompts

    Your app talks to the provider directly, never through us. On TEE models, nobody can.

  • Pays as you go

    Connect a Lexe or NWC wallet and it pays as you use. Or top up manually from any wallet.

No leftovers.

Pause whenever you like and every unspent dollar we pulled goes back to the wallet it came from. Unless you top up manually, we hold only your buffer, a turn by default: a small payment to start, then small payments as you use it.

Pay after use. New accounts prepay one turn. Every turn builds credit, and once your credit covers a turn, the prepayment ends. From then on your balance never goes above $0: you use first and pay after. If we're ever unreachable, your key stops at your credit limit and nothing else happens.

How refunds work

How it works

  1. Step 1

    Sign up.

    Just a password.

  2. Step 2

    Connect a wallet.

    Scan a code with your Lexe wallet and approve. Or skip it and top up manually.

  3. Step 3

    Use it anywhere.

    Any OpenAI-compatible app. Your wallet pays as you go, and you can pause and get the rest back.

Any model. Never through us.

Your prompts go from your app to the provider, never through us, and only the model's provider can read them. Locked models run in a secure enclave (TEE), so not even the provider can.

Questions

More in the docs.

Do I need a Lexe wallet?

It's the smoothest: a free, self-custodial Lightning wallet for iOS and Android. Wallets with Nostr Wallet Connect (NWC), like Coinos, Alby, Zeus and Primal, work too.Or use none: top up manually by paying an invoice from any Lightning wallet. Manual top-ups are non-refundable.

What do I pay up front?

$1 for a Tinfoil key, $5 for TrustedRouter. It isn't a fee: it's spent on your usage.

Can I get my money back?

Yes. Pause your account and every unspent dollar we pulled goes back to the wallet it came from, in sats at that day's rate, less a 0.5% network fee. Refunds are all or nothing, only to the wallet that paid, never in dollars. Invoices you paid yourself, including the $1 try-it, are non-refundable.

What's the pay-later limit?

How much you can use before paying. It grows with everything you use: after $20 of use on Tinfoil ($100 on TrustedRouter), your wallet only pays for what you've already used.

Can you see my prompts?

No, and neither can the router. Only the model's maker can, and in Tinfoil's secure enclaves not even they can.

What if a payment fails?

We retry. If your wallet declines, your keys pause until you add sats and press Pay now, or reconnect. Your dashboard shows what to fix.

What if I forget my password?

There's no reset, because there's no email. Use a password manager.

Do you know who I am?

No. We see payments and usage totals, never your name.
