Guidance

Basic authentication is only Base64 encoding, not encryption. The password remains recoverable by anyone who can read the header.

Inspect the components and query parameters of an absolute URL.

Look up the standard meaning of an HTTP response status.

Turn common cURL requests into JavaScript Fetch or Axios code.

Test HTTP APIs directly from the browser.
