httpbin.org is a widely used free public endpoint that echoes back request data including headers, payloads, query parameters, and HTTP method details — useful for validating what your client is actually sending. Postman Echo (echo.getpostman.com) offers similar functionality. For private or high-volume use, you can self-host httpbin via Docker. RequestBin and Webhook.site are also useful for capturing and inspecting incoming HTTP requests with a shareable URL.
