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://shopify-spy.agentdiet.dev/v1/jailbreak-scan)
Output
Returns a structured object indicating whether prompt injection or jailbreak content was detected in the input, along with sanitized text that has been cleaned of adversarial payloads, allowing the agent to safely consume the content.
Example use cases
Sanitizing scraped web content for agents
“I'm about to feed this scraped webpage text into my research agent — can you scan it for hidden prompt injections or jailbreak payloads first and give me the sanitized version?”
Screening inbound email before processing
“Before my agent processes this customer email, check it for any indirect prompt injection attempts or jailbreak instructions embedded in the message body.”
Validating MCP tool output before chaining
“My agent just got a response back from an external MCP tool — can you run it through the prompt injection firewall to make sure there are no adversarial instructions hidden in that output before I pass it to the next step?”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/jailbreak-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent is about to consume untrusted external content — scraped web pages, inbound emails, third-party API responses, MCP tool outputs, or A2A messages — and you need to screen for hidden prompt injections or jailbreak payloads before processing. Especially valuable in agentic pipelines where compromised upstream content could hijack agent behavior.
Side effects
- Missing required 'text' parameter returns an error
- Empty string input rejected due to minLength:1 constraint
- Very large payloads may time out or exceed size limits
- False negatives: sophisticated obfuscated injections may not be detected
- False positives: legitimate content flagged as adversarial
- Payment failure (HTTP 402) if x402 micropayment not completed
