How this service works
Live AI-citation check: runs fresh probes against major AI assistants and reports whether a domain is cited for its vertical's buying questions — citation rate per provider, list position, and whether the domain's agent-card was discovered. Fresh probes per call (not cached). $0.50 per check. Free companion diagnosis: /api/x402/deep-scan.
Output
Returns a structured object containing: the checked domain, per-provider citation results (array), overall citation rate (0–1), whether the domain's agent card was discovered (boolean), and a list of competitor domains mentioned by AI assistants instead of the queried domain.
Example use cases
Example prompt
“Can you check whether mudko.com is being cited by major AI assistants like ChatGPT and Claude when people ask buying questions in the website analytics vertical — I want to see the citation rate per provider, which competitors are being mentioned instead, and whether my agent card was discovered?”
Technical details
Endpoint
GEThttps://mudko.com/api/x402/citation-checkWhen to prefer
Use this endpoint when you need a real-time, non-cached measurement of whether a specific domain is cited by live AI assistants for buying-intent queries. Prefer this over cached SEO rank trackers or static audits when freshness matters — e.g. after publishing new content, updating an agent card, or after a competitor campaign. Choose this over the sibling deep-scan endpoint when you only need citation presence data and not a full site quality audit.
Side effects
- Missing required 'domain' query parameter returns 400 error
- Invalid or unresolvable domain returns empty or null provider results
- Payment not processed (x402) results in 402 Payment Required before probe runs
- AI provider APIs unavailable during probe window may return partial provider results
- Auto-detection of vertical fails for niche domains, requiring explicit 'vertical' parameter
