Search the global corpus of published fact-checks (ClaimReview) by free-text cla
Search the global corpus of published fact-checks (ClaimReview) by free-text claim. Returns matching claims with the claimant, claim date, and each fact-check review's verdict (textualRating, e.g. "False", "Misleading", "True"), the publisher (PolitiFact, Snopes, FactCheck.org, Reuters Fact Check, AFP, …), the review URL, and review date. Covers every topic — politics, health, science, viral and misinformation claims. Optional language, recency (maxAgeDays), and publisher-site filters. Aggregated by Google from publishers' schema.org ClaimReview data. Use it to check whether a claim has been independently fact-checked and how it was rated, rather than asserting from training data.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
