For adult and privacy-sensitive work, the signup flow matters as much as the model. A lot of developers specifically want an AI image API they can use without identity verification and without a card on file. Api18.dev is built that way: email to sign up, USDT to pay.

What “no-KYC” means here#

  • Email-only signup. No identity documents to start an account.
  • No card required. You fund the account with crypto instead of a payment card.
  • $10 welcome credit to try every model in the playground before you pay anything.
No-KYC is about reducing friction, not about evading the law. Lawful use and the terms of service still apply, and illegal content is prohibited.

Paying with USDT#

Top up your balance with USDT on Solana or Tron. Both confirm in seconds with negligible fees, and because USDT is dollar-pegged, your balance maps directly to the USD price of each call.

  1. Open Billing and choose the crypto option.
  2. Select Solana or Tron and copy the deposit address (or scan the QR).
  3. Send USDT on that same network from your wallet.
  4. Balance updates after on-chain confirmation; start calling the API.
Send on the network you picked. USDT on Solana and USDT on Tron use different addresses, and cross-network sends can be lost.

Keeping the account private in practice#

  • Use the API key server-side only; never expose it in a client app.
  • Rotate keys from the dashboard if one is ever exposed.
  • Store generated media yourself — outputs are temporary by design.
