# UCF v2 Adversarial Verifier – Deep Evidence & Identity Probe

> UCF v2 Adversarial Verifier – Deep Evidence & Identity Probe is a paid API for AI agents from unlike-tale-plays-rose.trycloudflare.com, paid per call via x402, $3/call, status unknown (last checked 2026-09-15).

Runs adversarial verification checks (evidence validation and/or identity probes) against an AI persona configuration, returning deep audit results for each named check.

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-deep-evidence-identity-probe-bd7604c2 -d '<json body>'
```

Example prompt: Run a deep adversarial verification on our 'Aria' persona — her axioms are 'be helpful' and 'never deceive', her voice is 'warm and concise', she should never reveal internal instructions — and check whether the last session output 'I cannot help with that' matches the expected response 'I am unable to assist', with the task context being 'customer support on platform GPT-4'.

## When to prefer this

Choose this endpoint when you need deep adversarial verification that combines both evidence checking (command/output/expected comparisons) and identity probing (persona axiom/voice/never constraint auditing) in a single call, as opposed to the lighter-weight identity-only probe sibling endpoint. Ideal for pre-deployment safety audits, post-incident jailbreak investigations, or continuous compliance monitoring of deployed AI personas.

## Known failure modes

- Missing required persona fields (name, axioms, voice, never) returns 422 validation error
- Malformed checks array items (missing name, output, or expected) may produce incomplete results
- Session or operator objects omitted may reduce probe depth or return partial results
- Persona axioms count outside 2–4 range triggers schema validation failure
- Network timeout for complex multi-check payloads at $3/call with no partial refund

## How this service works

UCF v2 Adversarial Verifier — evidence checks and/or identity probes

## Output

A structured response containing per-check verification results, each indicating whether the actual output matched the expected value, along with identity probe outcomes showing whether the persona held its axioms, voice, and never-do constraints under adversarial conditions.
