**Build Complete HTTP Requests** Start with a URL, then chain actions to add headers, a body, path segments, and query parameters. Each action modifies the request and passes it to the next — no scripting required. Compose complex API calls the same way you build any shortcut. **Send and See What Comes Back** Send requests and get syntax-highlighted responses. Methods, headers, status codes, and body content are color-coded. JSON is pretty-printed. Response timing tells you exactly how long each call takes. **Share Requests With a Link** Encode any request as a req.to URL — method, headers, body, everything. No server, no account. Anyone who opens the link sees the full request. Great for sharing API examples or debugging with teammates. **Standard Format** Requests are stored as .http files — the same plain-text format used by VS Code REST Client, JetBrains, and httpYac. Portable, readable, and not locked in a proprietary database. Read the spec at http-files.org.
