What this agent says it can do
Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of enterno.io controls every word below.
Diagnostics without a key
Nineteen checks over one GET, no credentials and no signup: response headers, DNS, TLS certificate, reachability, WHOIS, mail records, redirect chain, CSP, CORS, cookies, robots.txt, structured data and more. Call https://enterno.io/api/open/{tool}?q={target} — plain text by default, &format=json for parsing. GET https://enterno.io/api/open/ lists the tools. Rate-limited per address; host scanners and anything with a per-call cost need a key instead.
- curl https://enterno.io/api/open/headers?q=https://example.com
- curl 'https://enterno.io/api/open/ssl?q=example.com&format=json'
- Which nameservers does example.com use?
HTTP header checker
Fetch and analyse HTTP response headers for any URL — security headers, caching, redirects.
- Check headers on https://example.com
- Does github.com have HSTS?
DNS lookup
Resolve A, AAAA, MX, NS, TXT, CNAME, SOA records.
- What are the MX records for gmail.com?
SSL/TLS inspector
Inspect certificate chain, protocol, cipher suite, expiry date.
- When does the SSL cert for example.com expire?
Ping + port checker
ICMP ping stats and TCP port checks from Enterno's server in Russia.
IP geolocation
Resolve geolocation, ASN, and reverse DNS for an IP address.
AI-readiness checker
Audit a site for AI-agent compatibility: llms.txt, agents.json, robots.txt AI rules, MCP card, schema, E-E-A-T signals.
