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://x402-audit.agentdiet.dev/v1/jailbreak-scan)
Output
Returns a structured object indicating whether prompt injection or jailbreak content was detected in the submitted text, along with a sanitized version of the input safe for downstream agent consumption.
Example use cases
Safe web scraping for agent pipelines
“I just scraped this HTML from an external site and I want to feed it to you — but first, scan it for any hidden prompt injection or jailbreak instructions embedded in the page before you process it.”
Screening inbound emails for AI manipulation
“Before you summarize this inbound customer email for me, check it for any sneaky prompt injection attempts — someone could be trying to override your instructions through the email body.”
Validating third-party MCP tool responses
“This MCP tool just returned a response from an external server — can you run it through the jailbreak firewall to make sure there are no hidden instructions trying to manipulate your behavior before you act on it?”
Technical details
Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/jailbreak-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent is about to consume content from untrusted external sources — scraped web pages, user-submitted text, third-party API/MCP responses, or inbound emails — and you need to ensure no adversarial prompt injection or jailbreak payload is embedded before processing. Especially critical in agentic pipelines where indirect prompt injection via tool output is a realistic attack vector.
Side effects
- Empty or missing 'text' parameter returns a validation error
- Very large payloads may exceed size limits or time out
- Obfuscated or novel injection techniques may evade detection
- Non-text binary content may not be parseable
- Payment failure (HTTP 402) if x402 micropayment is not provided or rejected
