How this service works
Change watch for compression check: runs the check and compares it with the result from your previous call for the same url (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 http compression check changes. $0.01 per check.
Output
Returns the current HTTP compression check result for the given URL, a boolean 'changed' field indicating whether any values differ from the previous call, a detailed diff of exactly which fields changed with their before and after values, and the timestamp of when the result was last seen. Previous results are retained for 90 days.
Example use cases
Alert on compression being disabled
“Check if HTTP compression is still enabled on https://shop.acme.com and tell me if anything has changed since the last check — I want to know immediately if gzip or brotli gets turned off.”
Scheduled site performance audit
“Run a compression check on https://blog.mycompany.com and compare it to the previous result — show me exactly which fields changed and what the before and after values were.”
Post-deployment compression verification
“We just pushed a new deployment to https://api.startupxyz.io — can you check whether the HTTP compression status changed from what it was before the release?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/site/compressionWhen to prefer
Choose this endpoint when you need to detect changes in HTTP compression configuration over time rather than just a one-time check. It is ideal for scheduled agents that need to be alerted when a site's compression settings are added, removed, or altered. Prefer it over a plain compression check when diffing before/after values matters and you want persistent state across calls without managing storage yourself.
Side effects
- URL unreachable or returns non-200 response — check may fail or return an error state
- No previous result stored (first call) — 'changed' will be false or undefined, no diff available
- Results older than 90 days are purged — previous baseline lost, diff unavailable
- Payment failure (x402) — call rejected before executing
- Invalid or malformed URL input — schema validation error
