How this service works
Scans untrusted web pages, emails, MCP responses, or A2A payloads for hidden prompt injections and returns sanitized text. (Live x402 v2, IETF MPP & MCP endpoint at https://cve-intel.agentdiet.dev/v1/llm-jailbreak-defense)
Output
Returns a JSON object containing the scan result for the submitted text, including whether a prompt injection or jailbreak payload was detected and a sanitized version of the input text safe for downstream LLM consumption.
Example use cases
Sanitizing scraped web content for agents
“I'm having my agent read content from third-party websites to answer questions — can you run this scraped HTML through the jailbreak firewall first to make sure there are no hidden prompt injections embedded in it before my LLM sees it?”
Screening incoming email for AI manipulation
“My AI assistant reads my emails to triage them — before it processes this incoming message, please scan it for any indirect prompt injection attacks or hidden instructions trying to hijack my agent.”
Validating MCP tool response safety
“My agent just got back a response from an external MCP tool. Before I let it act on the result, can you check this payload for any jailbreak attempts or adversarial instructions hidden inside it?”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/llm-jailbreak-defense?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent is about to process content from untrusted external sources — web pages, emails, third-party tool responses, or A2A payloads — and you need to detect or neutralize hidden prompt injection or jailbreak attempts before they reach your LLM. It is purpose-built for agentic pipelines handling untrusted input and supports native x402 micropayment, making it suitable for automated agent workflows.
Side effects
- Empty or missing 'text' parameter returns a 400 validation error
- Extremely long inputs may be truncated or rejected
- Service unavailable (503) if the backend firewall is down
- Payment required (402) if x402 USDC micropayment is not included
- False negatives are possible for novel or obfuscated injection techniques
