Pay per use API

Use your Web3 wallet to pay per image • Network: Base

The pay-per-use model is based on the x402 open protocol created by Base. To integrate our API on a pay-per-use model you can refer to the x402 documentation .

1. Connect wallet

Connect MetaMask or another EVM wallet. The address is attached to your image requests.

2. Describe your image & choose a model

3. Check image status


          


        


        

          Note: the backend may return 402 Payment Required if no
          valid on-chain payment is detected yet for your wallet. You can implement additional contract calls in the
          frontend; the minimal example above just ensures the wallet is connected and tags requests with your address.
