How this service works
Is this website up? URL status check: reachable or not, HTTP status code, response latency in milliseconds, number of redirects, final URL and any connection or TLS error. Lightweight uptime probe and dead-link checker for monitoring and link validation. $0.01 per URL.
Output
Returns a JSON object indicating whether the URL is reachable, the HTTP status code received, response latency in milliseconds, number of redirects followed, the final resolved URL after any redirects, and details of any connection or TLS errors encountered.
Example use cases
Dead link detection before publishing
“Before I publish this blog post, can you check if https://old-partner-site.com/resource is still live and what status code it returns? I want to make sure I'm not linking to a broken page.”
Pre-flight URL check in automation pipeline
“Check whether https://api.thirdparty.io/v2/health is reachable right now, how many milliseconds it takes to respond, and if it redirects — I need to confirm it's up before triggering the next step in my workflow.”
Incident triage for downed page
“Our team got a report that https://checkout.mystore.com might be down — can you probe it and tell me the HTTP status, response time, and whether there are any TLS or connection errors?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/url-statusWhen to prefer
Choose this endpoint when you need a lightweight, fast probe of a single URL's availability, HTTP status, response latency, redirect chain summary, and TLS health without needing full redirect-chain detail or SSL certificate metadata. It is ideal for dead-link checking, pre-flight reachability validation in agent workflows, and simple uptime monitoring. For deep redirect chain analysis (every hop with per-hop latency), prefer redirect-chain-tracer; for full SSL certificate details (expiry, SANs, issuer), prefer ssl-certificate-expiry or site-uptime-and-ssl.
Side effects
- Target URL is completely unreachable (connection refused, DNS failure) — returns error details rather than HTTP status
- TLS/SSL handshake failure — returns TLS error description with no HTTP status
- Request times out — returns timeout error with no latency figure
- Malformed or invalid URL provided as input — likely returns a validation error
- Destination server returns non-standard or unexpected status codes — reported as-is
