Three modes

3 ways to charge agents.

All three settle in USDC over x402 and use the same FluxA wallet. Pick the one that fits your service.

MODE / 01ZERO CODE

Monetize Gateway

Put the Monetize proxy in front of your API. Every call gets charged via x402 before it ever reaches your backend.

Your API
  • Fixed per-call pricing, minimum $0.01.

MODE / 02DYNAMIC

x402 Payment Link

Creates a payment link for an AI agent. The agent reads the payment details and pays it via x402 itself.
