How this service works
Discover enterprise content syndication architecture: RFC 6596 cross-domain rel=canonical attribution, WebSub real-time push distribution, and RSS/Atom feed engineering.
Output
Returns a per-path availability and health report for the specified domain, including HTTP status of each probed path (default: /, /robots.txt, /sitemap.xml, /llms.txt), asset reachability results if requested, and signals relevant to canonical SEO and crawlability — all gathered from the service's independent QA node rather than the caller's own network.
Example use cases
Pre-launch site accessibility check
“Before we go live, can you probe newbrand.com from an external QA node to confirm that /, /robots.txt, /sitemap.xml, and /llms.txt are all reachable and the assets are loading correctly?”
SEO audit for syndication partner
“I'm onboarding a content syndication partner at publishersite.com — can you run a watchdog check on their domain to verify their sitemap and robots.txt are accessible and their canonical signals look right?”
Ongoing canonical tag monitoring
“Check myblog.com right now from the independent watchdog — I want to confirm /robots.txt, /sitemap.xml, and the homepage are all responding correctly after our recent migration.”
Technical details
Endpoint
POSThttps://articlesyndicator.net/api/a2a/x402/qa-watchdog?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an independent, third-party vantage point to verify domain and asset reachability rather than checking from your own network — particularly useful for validating SEO-critical files like robots.txt, sitemap.xml, and llms.txt as part of content syndication readiness, post-migration audits, or canonical attribution checks. Prefer it over generic uptime monitors when you need coverage of SEO-specific paths and canonical signal verification in a single call.
Side effects
- Domain not resolvable — DNS lookup failure for the provided hostname
- Target domain blocks external probes or returns 403/429 for watchdog IP range
- Paths array contains malformed or invalid path strings
- Network timeout when target domain is slow or unresponsive
- Payment not processed — x402 payment required before probe is executed
