What is a fact-checking API?

A fact-checking API takes a claim and checks it against a body of sources, returning a verdict rather than a list of links. The APITube fact-check endpoint checks a claim against a live index of 500,000+ news and web sources and returns a judged result with the evidence behind it.

How does the APITube fact-check endpoint work?

The APITube fact-check endpoint runs retrieval-augmented generation: it retrieves the coverage most relevant to your claim from the index, then returns a verdict together with the articles that support or contradict it. Sources carry an Open PageRank authority score, so you can weigh them.

What does the fact-check API return?

It returns a verdict on the claim plus the supporting and contradicting sources it was based on, each with its domain and authority. Your LLM or agent can cite those sources directly instead of asserting an unbacked answer.

Can I use fact-checking to ground an LLM or RAG agent?

Yes. Call the APITube fact-check endpoint before your model answers a factual question, then have the model cite the returned sources. This grounds the answer in current, attributable evidence instead of the training cutoff.

How is fact-checking different from a keyword news search?

A keyword search returns matching articles and leaves the judgement to you. The APITube fact-check endpoint goes a step further: it evaluates the claim against retrieved coverage and returns a verdict with the evidence, which is what an agent needs to act on.

How many languages and countries does fact-checking cover?

Fact-checking draws on the same index as the APITube news API: 500,000+ sources across 59 languages and 177+ countries, with a historical archive you can query by date range.

Is the fact-check endpoint available on the free plan?

Fact-checking runs retrieval-augmented generation over the index, so each check has a small credit cost and is available on paid plans. The standard news search and the full enriched schema remain available on the free plan.
