How this service works
DNS/TLS/HTTP health snapshot for a domain
Output
A structured health snapshot covering DNS resolution status, TLS/SSL certificate validity and expiry details, HTTP response code, and overall connectivity status for the queried domain. Returns a combined verdict so agents can quickly determine whether a site is reachable, secured, and properly configured.
Example use cases
Pre-launch site readiness check
“Before I announce my new site, can you check that myStartupDomain.com has valid DNS, a good TLS cert, and is returning HTTP 200 so I know it's actually live?”
Diagnosing a reported outage
“Users are saying they can't reach shopfront.io — can you run a health snapshot on it and tell me if DNS is resolving, TLS is healthy, and HTTP is responding?”
Automated infrastructure monitoring
“Every hour, check that api.mycorp.com is healthy — DNS resolving, TLS certificate valid, and HTTP responding — and alert me if anything looks broken.”
Technical details
Endpoint
GEThttps://agentx.sale/x402/site-health?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, combined DNS + TLS + HTTP health check for a domain in a single call, rather than running separate DNS lookup, SSL checker, or uptime monitor tools. Ideal for pre-launch validation, incident triage, or lightweight monitoring where a consolidated snapshot is more efficient than orchestrating multiple specialized tools.
Side effects
- Domain does not exist or fails DNS resolution — returns DNS failure status
- TLS certificate expired or invalid — flagged in TLS health field
- Site is unreachable or times out — HTTP status reflects no response
- Missing required 'host' query parameter — request rejected
- Network or upstream probe failure — may return partial or error snapshot
