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://polymarket-odds.agentdiet.dev/v1/jailbreak-scan)
Output
Returns a JSON object indicating whether prompt injection or jailbreak content was detected in the input text, along with a sanitized version of the text with any malicious instructions stripped or flagged.
Example use cases
Sanitizing scraped web content for agents
“I'm about to feed this web page HTML to my AI agent — can you scan it for hidden prompt injections or jailbreak payloads and return the safe, sanitized version before it touches my pipeline?”
Screening inbound emails for AI hijacking
“This email is going to be summarized by my AI assistant. Before it does, scan the email body for any embedded prompt injection attempts or jailbreak tricks and let me know if it's safe.”
Validating MCP tool response safety
“My agent just got a response back from an external MCP tool. Can you run that response text through the jailbreak firewall to make sure there are no hidden instructions trying to hijack what my agent does next?”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/jailbreak-scan?utm_source=zero.xyzWhen to prefer
Use this endpoint when your AI agent pipeline ingests untrusted external content — scraped web pages, user emails, third-party API or MCP responses, or A2A messages — and you need to detect and strip hidden prompt injection or jailbreak payloads before they reach your LLM. Prefer this over manual filtering when operating autonomous multi-agent systems where indirect prompt injection is a real attack surface.
Side effects
- Missing required 'text' parameter returns a 400/422 validation error
- Empty string input rejected due to minLength:1 constraint
- Very large payloads may timeout or be truncated
- Payment required (HTTP 402) if x402 micropayment header not provided
- False negatives possible for novel or obfuscated injection techniques
- Non-text binary content may produce unreliable scan results
