Install the payer

Let your AI assistant pay, from a small wallet of its own.

Early. Real money. Use with caution. A Solana payment cannot be undone. Put in only what you are ready to lose.

What it is

The Payzilla payer is a small open-source tool that runs on your computer. Your AI assistant uses it to pay a verified Marketplace listing in USDC on Solana, up to a cap you set. It pays from a separate small wallet. The wallet’s key stays in your computer’s keychain; Payzilla never sees it.

What limits it

  • The balance of the small wallet.
  • Your cap per payment: 0.50 USDC by default, up to 10 USDC.
  • At most 10 payments an hour.
  • Payzilla’s limits: 10 USDC per payment and 100 USDC a day across all users.

No person approves each payment. Above your cap, or when a limit is reached, it pays nothing and gives the listing’s pay link, so you can pay yourself.

Install

You need Node.js 24 or newer, on macOS, Windows or Linux.

  1. Get the code at a release tag and install it: npm ci --ignore-scripts.
  2. Make the small wallet: node src/small-wallet.ts init. It shows only the address.
  3. Send it a little USDC on Solana.
  4. Set your cap: node src/server.ts cap 0.50.
  5. Add it to your assistant, and add the Marketplace at https://paywith.payzilla.ai/mcp to find listings.
