AI that runs onmicropayments

Generate images, text, and audio with top models from Replicate. Authenticate with your wallet, authorize payment via x402, and pay per inference in USDC on Base.

USDC on Base · x402 settlement before compute · On-chain receipts per inference

How it Works

The x402 flow from authentication to on-chain settlement.

1

Sign in with Wallet

Authenticate via SIWE (EIP-4361). No email/password accounts or API key provisioning required.

2

Request Cost + Model Run

Choose a model and prompt. The API returns a 402 payment requirement with the estimated USDC amount.

3

Authorize USDC Transfer

Sign an EIP-3009 transferWithAuthorization payload. The x402 facilitator handles on-chain settlement on Base.

4

Get Your Result

Payment settles before compute starts. Receive your result plus a payment receipt hash, then keep it private or share it publicly.

Everything you need, nothing you don't

AI inference should be open, affordable, and verifiable.

True Pay-Per-Use
No subscriptions, no credits, no minimums. Inference is billed in USDC based on execution time using the configured protocol rate.
Wallet is Your Identity
No sign-ups, no API keys to manage. Connect your Web3 wallet and you're in. Sign-In With Ethereum keeps it simple.
Multi-Model Access
Flux, Stable Diffusion, Llama, Mixtral, Stable Audio, and more. One interface for text, image, and audio models.
On-Chain Settlement
Every payment is verified and settled on Base before your inference runs. Transparent, auditable, and trustless via x402.
