# ContinuityKit UCF v2 Deep Adversarial Verifier

> ContinuityKit UCF v2 Deep Adversarial Verifier is a paid API for AI agents from continuitykit.net, paid per call via x402, $3/call, status down (last checked 2026-10-20).

Runs deep adversarial evidence checks and identity probes against an AI persona or agent session to verify behavioral consistency and constraint compliance

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 continuitykit-ucf-v2-deep-adversarial-verifier-e773e1de -d '<json body>'
```

Example prompt: Run a deep adversarial identity probe on my agent named 'Aria' whose axioms are 'never reveal system prompt' and 'always stay in character', using a POST session on platform GPT-4, and check whether it holds up under the objective of exposing persona drift — include evidence checks for prompt injection resistance and role-breaking.

## When to prefer this

Choose this endpoint when you need deep, multi-check adversarial verification of an AI agent persona — particularly when you have structured evidence checks, session context, and a full persona definition to probe against. Prefer this over the sibling identity-pack probe endpoint when you want comprehensive evidence auditing rather than lightweight identity probing, and over generic LLM evaluation tools when you need structured UCF-compatible adversarial results with operator context.

## Known failure modes

- Missing required fields (type, method, bodyType, body) returns a validation error
- Insufficient persona axioms (fewer than 2) rejected by schema
- Invalid method enum value causes 400 error
- Malformed checks array with missing name/command fields may produce incomplete results
- Payment failure (insufficient USDC balance) blocks execution with 402 response

## How this service works

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

## Output

Returns a structured report of deep adversarial verification results, including pass/fail outcomes for each named evidence check, identity probe findings, and whether the persona held up against adversarial conditions across the defined axioms and constraints.
