Online fact checks: use Snopes without losing context
Match the exact claim, inspect the reasoning, and preserve dates and qualifications when using published fact checks.
06 FIELDNOTES / TOPIC
Evidence
A focused reading path through The Evidence Journal. The common thread across FactAPI.com is an inspectable relationship between a claim and the material that supports, conflicts with, or fails to resolve it. Browse practical guides for preserving that relationship through extraction, retrieval, assessment, and publication.
How to use this collection
Use this collection to spot the boundaries that disappear in a confident summary: source scope, dates, qualifications, attribution, and unresolved gaps. A relevant document is not automatically supporting evidence, and a citation marker is not an assessment. The articles below approach that distinction from complementary engineering and editorial perspectives.
Start with the Fact API guide, then follow the fieldnotes below. All examples are illustrative and each article points to its own editorial source.
