AI Agent Integration Validation Tool Launches

The author launched fetchsandbox on Product Hunt, quickly climbing to the #3 spot of the day.
The motivation behind the tool is a common pitfall: AI agents writing Stripe/Twilio integrations often pass standard tests but fail in production when handling real webhooks, duplicate events, non-idempotent processes, or retries triggering stale states. fetchsandbox runs the full integration lifecycle before deployment, featuring real workflows, authentic webhooks, on-demand failure injections, and a publicly shareable receipt URL to prove stability directly within a PR.
The author also poses a question to the community: if you are building agents that interact with third-party APIs or handle payments/communications, how are you currently handling pre-launch validation?
