Most API testing tools just check if a request returns a 200 OK status, but FetchSandbox goes much further. It allows developers and AI agents to verify complex behaviors like webhooks, retries, state changes, and failure scenarios. It helps you reproduce actual bugs, prove your fixes work, and build a history of what breaks so your AI agents can catch issues before they reach production. You can connect it to tools like Cursor, Claude Code, and VS Code via MCP. It gives you access to over 60 popular APIs, including Stripe and GitHub, without needing to spend your real API quota or rely on slow staging environments.
