# DCL Trust Oracle — Jailbreak & Prompt Injection Detector

> DCL Trust Oracle — Jailbreak & Prompt Injection Detector is a paid API for AI agents from bazaar.fronesislabs.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Evaluates agent inputs for jailbreaks, prompt injection attempts, and instruction conflicts before execution

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 dcl-trust-oracle-jailbreak-prompt-injection-detector-7f5d34b8
```

Example prompt: Before I process this user message, run it through the DCL Trust Oracle jailbreak evaluator to check if it contains prompt injection or instruction conflicts — give me the verdict, confidence score, and reason.

## When to prefer this

Choose this endpoint when you need lightweight, fast pre-execution screening of agent inputs for adversarial manipulation — specifically jailbreaks, prompt injection, and instruction conflicts — before an agent acts. It is most valuable in agentic pipelines where untrusted user input feeds into autonomous decision-making, especially for irreversible or sensitive actions. Prefer this over general content moderation when your threat model centers on adversarial prompt-level attacks rather than harmful content categories.

## Known failure modes

- Missing required 'input' parameter returns validation error
- Unsupported HTTP method (only GET/HEAD/DELETE accepted) returns 405
- Payment not provided or insufficient USDC results in 402 Payment Required
- Malformed query parameters may return 400 Bad Request
- Service unavailability returns 503 with no verdict

## How this service works

Detect jailbreaks, prompt injection, and instruction conflicts before the agent follows them.

## Output

Returns a verdict (e.g. 'safe', 'jailbreak', 'injection'), a confidence score (0-1), a human-readable reason, a drift score and drift mode indicating behavioral deviation, the policy version used, a hash of the input, a blockchain transaction hash for auditability, a chain index, and a timestamp.
