## 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 second-opinion-panel-verdict-f811a937 -d '<json body>'
```

Example prompt: Run this claim through the full three-skeptic panel — evidence, logic, and currency — and give me the majority verdict with each seat's breakdown: 'mRNA vaccines alter human DNA permanently.'

## When to prefer this

Choose this endpoint when you need a robust, multi-perspective verdict rather than a single-agent check — especially for high-stakes claims where a single reasoning path might miss flaws. It is superior to the quick or single-agent variants when thoroughness matters more than speed, and when you specifically want the evidence, logic, and currency dimensions evaluated independently and a majority vote to resolve disagreements.

## Known failure modes

- Missing or empty claim body returns 400 bad request
- Payment not settled via x402 protocol returns 402 Payment Required
- Ambiguous or very short claims may produce low-confidence verdicts with no clear majority
- Service timeout if claim requires extensive multi-agent processing
- Malformed bodyType enum value returns 422 unprocessable entity

## How this service works

Second Opinion panel: three independent skeptics attack the claim via different lenses (evidence, logic, currency). Majority verdict with per-seat breakdown.

## Output

Returns a majority verdict (e.g. supported/refuted/uncertain) plus a per-seat breakdown from three independent skeptic agents, each attacking the claim through a distinct lens: (1) empirical evidence, (2) logical validity, and (3) currency/recency of supporting information.
