# UCF v2 Adversarial Verifier – Identity-Pack Probes

> UCF v2 Adversarial Verifier – Identity-Pack Probes is a paid API for AI agents from unlike-tale-plays-rose.trycloudflare.com, paid per call via x402, $1/call, status unknown (last checked 2026-09-13).

Runs adversarial probe checks against a structured AI persona/identity pack to verify robustness, consistency, and boundary integrity.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 ucf-v2-adversarial-verifier-identity-pack-probes-0b768c15 -d '<json body>'
```

Example prompt: Run an adversarial probe on my persona pack — the persona is named 'Aria', her axioms are 'always be honest' and 'never manipulate users', her voice is 'calm and empathetic', she must never insult users or break character, and the operator is 'Acme Corp' acting as 'customer support lead'. Check if she holds up.

## When to prefer this

Choose this endpoint when you need to adversarially stress-test a UCF v2 persona/identity pack before deployment, specifically running identity probes to check if the persona resists manipulation, stays in-voice, and honors its never-do constraints. Prefer this over generic LLM safety checkers when working within the UCF (Unified Character Framework) v2 ecosystem and needing structured probe results tied to persona axioms, voice, and operator context.

## Known failure modes

- Missing required persona fields (name, axioms, voice, never) returns a 400-level validation error
- Axioms array outside min/max bounds (fewer than 2 or more than 4) causes schema rejection
- Missing required operator fields (name, role) returns a validation error
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Transient Cloudflare tunnel errors may cause 503 or connection timeouts
- Malformed session memory array causes unpredictable probe behavior

## How this service works

UCF v2 Adversarial Verifier — identity-pack probes

## Output

Returns a structured adversarial verification report indicating whether the persona pack passed or failed identity probes, with details on which axioms, voice constraints, or never-do rules were challenged and whether they held, along with any boundary violations or consistency failures detected.
