## 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 mcx-ventures-deep-adversarial-verification-8e2c87e7 -d '<json body>'
```

Example prompt: Run a deep adversarial verification on this claim — put it through the full Skeptic, Verifier, and Red Team pipeline and tell me everything that doesn't hold up: 'Our platform has processed over $2 billion in transactions with zero security incidents since 2019.'

## When to prefer this

Choose this deep-tier endpoint over the basic or standard tiers when the content under review is high-stakes (investment decisions, legal claims, published research, security assertions) and you need the full three-layer Skeptic + Verifier + Red Team treatment rather than a single-pass critique. Prefer this when you specifically need red team adversarial attack scenarios, not just a skeptic review or a two-layer check.

## Known failure modes

- Missing or empty payload field returns a 400/422 validation error
- Payment not provided or x402 payment failure results in a 402 Payment Required response
- Payload too large or malformed body type causes a parsing error
- Network timeout if payload is very long and processing exceeds limits
- Non-POST method returns 405 Method Not Allowed

## How this service works

Adversarial verification, deep tier — Skeptic + Verifier + Red Team

## Output

A structured deep-tier adversarial report containing three layers of analysis: a Skeptic critique identifying weaknesses and doubts, a Verifier assessment cross-checking claims, and a Red Team attack surface identifying the most hostile counterarguments and failure points — returned as a detailed textual or structured response.
