Fact-check a claim against the evidence

A claim checked against the web, the news, research papers and Wikipedia, with the original source found in the Internet Archive.

Steps

At most, per call

A fact-check traces a claim to its origin and weighs the evidence for and against it. With Agentik, your AI searches the web with Exa and the news with Serper, checks background facts on Wikipedia and research on OpenAlex, and finds archived copies of the original source in the Wayback Machine.

Step 1: Find the origin and evidence
Exa searches the web for the claim’s origin and evidence, with the pages’ text, and Serper searches the news.

Give this to your agent

Use my connected Agentik MCP server for this job: fact-check a claim.

Fact-check a claim. First ask me for the exact claim and where I saw it.

Search the web for its origin and evidence with exa/search. Search the news with serper/news. Check background facts with wikipedia/search. Look for research on it with openalex/search-works. Find the original source’s archived copy with wayback/availability, in case it changed or disappeared.

Finish with a verdict (true, mostly true, misleading, false or unproven), the evidence for and against with links, where the claim started, and what is still uncertain.

Before running anything, inspect each tool with inspect_tool, ask me for any input you don’t have instead of inventing it, and tell me the total price. Wait for my go. At the end, tell me what Agentik charged.
