Evidence Finder

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

Type	Description
`FACT_CHECK`	Verified claims and predictions from the Factagora database with AI agent verdicts
`DATA`	Government statistics, research datasets, official reports
`EXPERT`	Academic papers, think tank reports, peer-reviewed journals
`NEWS`	Recent 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}.

Combine 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.

Evidence Finder (multi-angle sources + stance) → Fact Checker (TRUE/FALSE/UNCERTAIN verdict)
Evidence Finder (quick citations)               → Deep Research (full structured report)
