## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability money-mind-fact-check-multi-source-claim-verifier-3d87b5cf -d '<json body>'
```

Example prompt: Can you fact-check the claim that Apple's Q3 2024 revenue was $85.8 billion against these three sources — [URL1], [URL2], [URL3] — and tell me whether the sources are consistent, conflicting, or if there's insufficient evidence?

## When to prefer this

Choose this endpoint when an agent needs to verify a specific claim or figure against multiple independent sources before taking action, rather than doing separate extractions and comparisons itself. It is especially useful for financial figures, reported statistics, or any claim where source agreement matters. It replaces 2-4 separate extraction calls plus manual comparison logic at $0.03 total. Prefer this over generic search or scraping when you need a structured verdict with cited evidence, not just raw page content.

## Known failure modes

- Source URL is behind a paywall or requires authentication — extraction fails for that source, potentially degrading to insufficient_evidence
- Fewer than 2 sources successfully extracted — verdict cannot be rendered
- Claim contains no checkable numeric figures — comparison may be inconclusive
- Source pages have changed since claim was made — figures may not match original context
- Rate limiting or timeout on source fetch — confidence score lowered or source skipped

## How this service works

Verify a claim against 2-4 source URLs: cited passages, cross-source agreement, verdict: consistent | conflicting | insufficient_evidence. Evidence, not truth. Use when your agent needs to verify a claim against independent sources before acting on it. Give a claim plus 2-4 source URLs; each source is extracted (three-fetch cross-check, confidence-scored), the checkable figures are compared across sources, and you get the cited passages plus a verdict: consistent (sources report the claim's figures), conflicting (sources agree with each other on different figures), or insufficient_evidence. This sells evidence, not truth — the verdict describes source agreement and says so. One $0.03 call replaces three separate extractions plus your own comparison. Money Mind sells judges, not strategies. This company has no proven edge and does not sell signals, forecasts or data.

## Output

Returns cited text passages extracted from each source URL, a comparison of checkable figures across sources, a confidence score for each extraction, and a verdict of 'consistent' (sources agree on the claim's figures), 'conflicting' (sources agree with each other but on different figures than claimed), or 'insufficient_evidence' (sources could not be reliably extracted or compared).
