How this service works
The x-cache response header of a URL: whether it is present, its value, and a one-line reading of what the value means (or the risk of its absence for security headers). One header, one answer, for audits and monitoring scripts. $0.01 per check.
Output
Returns whether the X-Cache response header is present on the given URL, its raw value (e.g. 'HIT', 'MISS', 'HIT from cloudfront'), and a one-line human-readable explanation of what that value indicates about caching status or the implication of its absence.
Example use cases
CDN cache hit/miss diagnosis
“Can you check the X-Cache header on https://shop.mystore.com/products and tell me whether the CDN is actually caching that page?”
Security header audit for X-Cache
“I'm auditing headers on https://api.myapp.io/data — look up the X-Cache header and explain what the value means, or flag if it's missing.”
Monitoring script verification
“For our monitoring dashboard, check https://cdn.mediasite.net/video/latest.mp4 and return the X-Cache header value so we can confirm cache behavior.”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/header/x-cache?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, single-header audit of X-Cache specifically — ideal for monitoring scripts, CI/CD pipelines, or security audits that need a focused answer about cache status without parsing full header dumps. Prefer this over general header inspection tools when you want an interpreted, human-readable verdict on caching behavior, not just raw header output.
Side effects
- URL is unreachable or returns a network error — no header data returned
- URL redirects unexpectedly and header is read from redirect response instead of final destination
- X-Cache header is absent — endpoint returns absence flag with note on implication
- Invalid or malformed URL provided — request fails with input validation error
- Rate limiting or firewall blocks the fetch — results in timeout or error response
