What This Skill Does

Checks factual claims against live data sources and returns a structured verdict with confidence score, current truth value, and freshness indicator. Supports category hints for financial data, entity facts, geographic data, and general fact-checking via Google Fact Check API. Free tier allows 25 queries per day with no authentication.

Returns live-sourced verdicts with confidence scores and a freshness indicator, so agents can distinguish claims that are currently true from those that were once accurate but have since changed.

When to use it

  • Confirming a currency exchange rate before including it in a report
  • Checking whether a company founding date in a draft article is accurate
  • Validating a cryptocurrency price claim inside a chatbot response
  • Flagging population statistics in research docs that may have gone stale
  • Catching outdated facts in automated content pipelines before publishing
