Payment Gate

Add a payment requirement to any API endpoint — agents receive 402 and must sign an EIP-712 authorization to proceed.

Fixed Pricing

Charge a fixed micro-payment per API request using the Express or FastAPI middleware with one decorator.

Variable Pricing

Set dynamic payment amounts based on request parameters, usage tiers, or content type at runtime.
