Httpbin

A streamable HTTP testing and debugging server that wraps httpbin functionality into two simple tools: get and post. You can inspect request/response cycles, test status codes, add delays, and generate UUIDs or base64 data. It's the kind of thing you reach for when building or debugging HTTP integrations and need a reliable echo endpoint that shows you exactly what you sent. Part of the Pipeworx gateway ecosystem, so you can either use it standalone or access it alongside 250+ other data sources through their unified endpoint. The ask_pipeworx interface lets you query in plain English instead of calling tools directly.
