How to use HTTP status code reference
  1. 1
    Paste your input

    Enter the value at the top — domain, IP, URL, email, ASN, hash, whatever fits this tool. The smart input auto-detects type.

  2. 2
    Click "Inspect"

    host.tools issues real probes (DNS, HTTP, TCP, TLS, WHOIS where applicable) and renders the result in milliseconds.

  3. 3
    Open the API tab

    Every web tool has a sibling /api/v1/utility/http-status JSON endpoint with the same payload. One copy-as-curl click and you're scripting it.

API equivalent
/api/v1/utility/http-status?q=200

Embed this tool
<iframe src="/utility/http-status?q={INPUT}&embed=1"
  width="100%" height="600" frameborder="0"></iframe>
