How this service works
Check public domain DNS, HTTP, HTTPS, redirects, TLS certificate health and response latency in one request.
Output
Returns a JSON object containing: the domain checked, the final URL after redirects, number of redirects, DNS status (e.g. 'ok'), an array of diagnostics, HTTP status code, HTTPS status code, response latency in milliseconds, and TLS certificate expiry timestamp.
Example use cases
Pre-launch domain verification
“Before we go live, can you check that example.com is fully healthy — confirm DNS is working, HTTPS is returning 200, and that the TLS cert isn't about to expire?”
Investigating a reported outage
“Users are saying they can't reach acmecorp.io — can you run a domain health check and tell me what the DNS status, HTTP and HTTPS responses are, and how long it's taking to respond?”
Monitoring redirect chains
“Can you check howmanyredirects.com and tell me how many redirects are happening before we hit the final URL, and what that final URL is?”
Technical details
Endpoint
POSThttps://relay.straelo.com/domain-health?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive single-call domain health snapshot covering DNS, HTTP, HTTPS, TLS, redirects, and latency together. Prefer it over ad-hoc ping or manual curl checks when you need machine-readable structured results suitable for agent workflows or automated monitoring pipelines.
Side effects
- Domain does not exist or cannot be resolved — DNS status will reflect failure
- Domain is unreachable — HTTP/HTTPS status fields may be null or error codes
- TLS certificate information unavailable — tls_certificate_expires_at returns null
- Invalid domain input format — API may return a validation error
- Upstream timeout — response latency may be high or request may fail
