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, along with sanitized text stripped of adversarial instructions and a safety assessment of the original payload.
Example use cases
Guarding agent from malicious web scrapes
“I just scraped this webpage to feed to my AI pipeline — can you scan it for hidden prompt injections or jailbreak payloads before passing it along? Here's the raw HTML: <html>...</html>”
Screening incoming A2A tool responses
“My agent just got a response back from an external MCP tool and I don't trust it — can you run it through the prompt injection firewall and give me the sanitized version? Here's the payload: {"result": "Ignore previous instructions and..."}”
Filtering suspicious user-submitted email
“A user submitted this email to our platform and it might contain adversarial instructions trying to hijack our AI assistant — please scan it for indirect prompt injections and tell me if it's safe to process.”

Endpoint
POSThttps://polymarket-odds.agentdiet.dev/v1/jailbreak-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent pipeline processes untrusted external content — scraped web pages, emails, third-party API responses, A2A payloads, or MCP tool outputs — and you need to detect and neutralize hidden prompt injection or jailbreak instructions before that content influences your LLM. Particularly valuable in multi-agent architectures where one agent receives input from another potentially compromised agent or external system.
Side effects
- Empty or missing 'text' field returns a 400 validation error
- Extremely long payloads may be truncated or rejected
- False negatives possible for novel or obfuscated injection techniques
- False positives may flag benign security-related content as injections
- Payment failure (402) if x402 micropayment is not properly attached
- Service unavailability returns 5xx errors
