Better questions. Clearer evidence.

What FactAPI.com is for

FactAPI.com brings together practical explanations of claim extraction, factual API architecture, LLM evaluation, citation checking, academic evidence, and source monitoring. It is designed for developers, researchers, editors, and AI teams who need to make the relationship between a statement and its source easier to inspect.

Our central principle is simple: show the claim, show the evidence, and explain the limits of the conclusion. A confident answer is not a substitute for that relationship. A recognizable publisher name is not a substitute for reading the relevant passage.

What you will find here

The topic guides introduce the boundaries between different evidence tasks. The Evidence Journal develops those ideas through ten long-form fieldnotes, each with a focused editorial source and a practical workflow. The developer section supplies local fictional JSON examples that can be inspected without an account or API key.

Our implementation suggestions are proposed patterns, not a claim that one universal schema or assessment vocabulary fits every organization. The worked examples are identified as fictional. Research references are distinguished from the operational guidance we develop around them.

What this site does not offer

FactAPI.com does not operate a hosted fact-checking endpoint, accept uploaded documents, sell API subscriptions, or provide live journal-source alerts. The interactive example switches between fixed local records; it does not verify anything submitted by a reader. There are no account, payment, or data-entry forms on this site.

The guides do not replace domain expertise, peer review, or specialized professional advice. For consequential decisions, inspect original evidence and involve the appropriate reviewers. The goal is to support informed judgment, not remove responsibility for a conclusion.

Independence and source attribution

References to Snopes, Google, Crossref, W3C, NIST, and academic research describe their public material. They do not imply endorsement, affiliation, a data partnership, or an official integration. FactAPI.com does not claim credentials, certifications, or service-performance results from those organizations.

Visit the research source index to see the primary references behind the guides. The editorial policy explains how we distinguish evidence, inference, and illustrative design.
