How this service works
Change watch for hsts preload check: runs the check and compares it with the result from your previous call for the same domain (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when hsts check changes. $0.01 per check.
Output
Returns the current HSTS preload check result for the domain, a boolean 'changed' flag indicating whether the result differs from the previous call, an itemized list of which fields changed with their before and after values, and the timestamp of when the previous result was last seen. Previous results are retained for 90 days.
Example use cases
Detect HSTS preload eligibility milestone
“Check the HSTS preload status for myshop.com and tell me if it has changed since the last time — specifically whether it became eligible for the preload list.”
Security audit change tracking
“I'm auditing security configs for clientsite.org — run the HSTS preload check and compare it to the previous result so I can see if any fields have changed and what they were before.”
Scheduled compliance monitoring
“I want to run a recurring HSTS preload check for app.fintech-startup.io every week and get notified whenever the result differs from the prior check, with the exact before and after values for each changed field.”

Endpoint
GEThttps://intel.rallylive.ca/watch/site/hsts-preloadWhen to prefer
Choose this endpoint when you need to detect changes in HSTS preload eligibility over time rather than just a one-time status check. It is ideal for scheduled/polling workflows, compliance monitoring pipelines, or alerting systems where knowing what changed (with exact before/after field diffs) is more valuable than raw current state. Prefer it over a plain HSTS check when historical comparison and change detection are the primary goal.
Side effects
- Domain not provided or invalid — check will fail or return an error
- No previous result stored (first call) — changed flag may be false or undefined, no diff available
- Previous result older than 90 days — comparison data expired, treated as first call
- Domain unreachable or DNS failure — check cannot complete
- Payment not processed — 402 response, check not run
