## What it does

The hosted server checks public websites. It can report HTTP status and redirect paths, inspect DNS and TLS certificates, and grade security headers. Other tools cover email records, SEO, AI-crawler readiness and network checks such as ping and traceroute.

This is a remote HTTP service, not code that runs in your project. An Enterno.io API key is required for tool calls; without one, the server returns HTTP 401. Requests to private, local and internal addresses are refused. Keep the key out of files committed to your repository.

## When to use it
- check a site's HTTP status and redirect path
- find a TLS certificate's expiry and negotiated cipher
- review security headers and spot missing ones
- inspect a domain's SPF, DKIM and DMARC records
- audit on-page SEO and AI-crawler readiness

## Example prompts
- Check the site's HTTP status and response time.
- Find when the site's TLS certificate expires and which cipher it negotiates.
- Review the site's security headers and list any that are missing.
