How this service works

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.

Output

Returns an array of matched claims, each with the original claim text, the claimant, the claim date, and one or more fact-check reviews. Each review includes the publisher name, review date, URL, and a textual rating (e.g. 'False', 'Mostly True', 'Misleading'). Also includes metadata like total count, the query used, and the source attribution (Google Fact Check Tools / ClaimReview).

Example use cases

Example prompt

“Has the claim that 'the COVID vaccine contains microchips' been fact-checked? Search for up to 5 English-language reviews from the last 365 days and tell me who made the claim and what the fact-checkers concluded.”

Technical details

Endpoint

GEThttps://2s.io/api/factcheck/search?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to check whether a specific claim or statement has been reviewed and rated by professional fact-checkers. Ideal for misinformation detection, journalism support, or verifying viral social media claims. Prefer this over web search when you want structured, sourced ratings from known fact-checking publishers like FactCheck.org, PolitiFact, or Snopes.

Side effects

No matching claims found — returns empty items array with total:0
Invalid language code returns validation error
Limit out of range (must be 1–50) causes a 400 error
Very broad queries may return unrelated claims
Some claims may lack claimant or claimDate fields (nullable)
Recent claims may not yet be indexed by Google Fact Check Tools
