Agentic finance tools

Working utilities for builders pricing and shipping machine-payable APIs. Everything runs locally in your browser.

Set price and traffic → monthly revenue, x402 fees, and what the same pricing would lose on card rails. Find your micropayment sweet spot.

Four fields → ready-to-use 402 JSON body, curl test, and a Cloudflare Worker snippet. Includes USDC atomic-unit conversion.

Already have a live endpoint? Validate that it returns a correct 402 payment requirement (external tool).
