header.sbs automatically detects the request format and responds accordingly:

  • Browser requests receive this HTML page
  • Requests with Accept header set to application/json receive JSON response

curl -H "Accept: application/json" https://header.sbs

Perfect for debugging, API testing, or understanding what your client is sending.
