​
Use specific, declarative claims

Evidence Finder works best with concrete, specific statements rather than open-ended questions. 
# Good, specific and declarative
claim=Bitcoin price will exceed 200000 dollars in 2025

# Avoid, open-ended question
claim=Will Bitcoin hit 200k?

​
Use stance to build balanced views

Each result includes a stance field indicating whether the source SUPPORTS, CONTRADICTS, or is NEUTRAL toward your claim. Use this to present multiple perspectives. 
// Show supporting evidence
const supporting = results.filter(e => e.stance === 'SUPPORTS');

// Show contradicting evidence
const contradicting = results.filter(e => e.stance === 'CONTRADICTS');

​
Filter by credibility score

credibility is an AI-generated confidence score (0–1) for how strongly a source supports or contradicts the claim, not a static measure of outlet reputation. A score above 0.8 means the source directly and clearly addresses the claim, while lower values indicate a weaker or more indirect connection. Use it to prioritize the most relevant evidence. 
// Only show credibility >= 0.8
results.filter(e => e.credibility >= 0.8)

​
Use evidence types to understand the source

TypeDescription
FACT_CHECKVerified claims and predictions from the Factagora database with AI agent verdicts
DATAGovernment statistics, research datasets, official reports
EXPERTAcademic papers, think tank reports, peer-reviewed journals
NEWSRecent news coverage from reputable outlets
FACT_CHECK sources link directly to Factagora claims or predictions at https://factagora.com/claims/{uuid} or https://factagora.com/predictions/{uuid}.

​
Pair with Fact Checker or Deep Research

Use Evidence Finder to gather raw supporting/contradicting sources, then feed the claim into Fact Checker for a verdict or Deep Research for a full report.
