# Evidence Finder

> Best practices for Evidence Finder

## Use specific, declarative claims

Evidence Finder works best with concrete, specific statements rather than open-ended questions.

```bash theme={null}
# 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.

```json theme={null}
// 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.

```json theme={null}
// 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}`.

## 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.

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