Summary
Reach for this when you need to validate webhook integrations without spinning up your own infrastructure. It connects to a hosted endpoint at webhook-tester.api.klymax402.com and runs over SSE transport. You can fire test requests at webhook URLs, measure response latency, and validate payloads coming back. The x402 micropayment integration suggests it's metered usage, though the GitHub repo doesn't expose implementation details beyond TypeScript source. Useful for debugging third-party webhook configs or load testing callback handlers before you wire them into production systems.
