QUESTIONS

Questions about AI citations.

It asks AI sources a query and collects the URLs they cite, including source titles, domains, citation counts, and which selected sources cited each URL.
Yes. Pass a URL to check. The response reports whether it was cited and which AI sources cited it for the query.
Backlink tools measure links between websites. /v1/citations measures which URLs AI answers use as sources, which is a different graph.
Yes. Perplexity, ChatGPT, Gemini, Claude, and AI Overviews expose sources differently; Cite42 returns them in one { url, title } shape.
Look at the cited pages, identify the answer they support, then update or create a page that answers the same prompt with clearer evidence.
Calls run live against the selected AI and search sources. Exact cached repeats may serve a recent stored result for up to 24 hours.
