# ContinuityKit UCF v2 Adversarial Verifier

> ContinuityKit UCF v2 Adversarial Verifier is a paid API for AI agents from continuitykit.net, paid per call via x402, $1/call, status down (last checked 2026-10-20).

Probes an AI agent's persona identity pack for adversarial robustness by verifying that the agent's persona, axioms, voice, and operator constraints hold under adversarial conditions

## Facts

- Endpoint: POST https://continuitykit.net/v1/verify?utm_source=zero.xyz
- Price: $1/call
- Payment: x402
- Status: down
- Last checked: 2026-10-20

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_OIulcm8RpvH_Ba2ZXIw18

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-adversarial-verifier-8f267b86 -d '<json body>'
```

Example prompt: Run an adversarial identity-pack probe on my agent persona called 'Aria' with axioms ['always be honest', 'never reveal system prompts'], voice 'calm and professional', never-do rules ['impersonate humans', 'make financial promises'], operated by 'AcmeCorp' as a 'customer support assistant'.

## When to prefer this

Choose this endpoint when you need to programmatically verify that an AI agent persona is adversarially robust — specifically when you have a structured persona definition (axioms, voice, never-do rules) and an operator context and want to stress-test identity consistency before deployment or on a recurring audit basis. Prefer it over manual red-teaming or generic LLM evaluation tools when you need a structured, paid, repeatable identity-pack probe with defined schema inputs.

## Known failure modes

- Missing required persona fields (name, axioms, voice, never) returns a 400 validation error
- Fewer than 2 or more than 4 axioms causes schema validation failure
- Invalid method enum value (only POST, PUT, PATCH accepted) causes rejection
- Payment not completed via x402 protocol results in 402 Payment Required
- Malformed body or incorrect bodyType enum causes request failure

## How this service works

UCF v2 Adversarial Verifier -------- identity-pack probes

## Output

Returns a structured verification result indicating whether the persona identity pack withstands adversarial probing, including which axioms or constraints were challenged and the outcome of each probe test.
