How this service works
Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.
Output
Returns a JSON object with an 'ok' boolean, a 'mode' string identifying the shield type ('tool_response_injection_shield'), a 'risk' field (e.g. 'low', 'medium', 'high'), and a 'findings' array listing any detected threats or anomalies in the submitted content.
Example use cases
Guarding agent from injected instructions
“I just got a response back from a third-party tool and I'm worried it might contain hidden instructions trying to hijack my agent — can you scan it through the response shield and tell me the risk level before I process it?”
Automated safety check in agent pipeline
“Every time my agent fetches external data, I want to run the tool response through the injection shield and only continue if the risk comes back as low — can you set that up?”
Post-fetch validation before code execution
“My agent pulled some content from a GitHub bounty endpoint — before it does anything with that data, scan it for injection attempts and show me any findings so I can decide if it's safe to proceed.”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/tool-response-shield?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent is consuming tool or API responses from untrusted or external sources and needs to verify that the content does not contain prompt injection, response poisoning, or manipulation attempts before taking action. Prefer this over generic content filters when the specific threat model is tool-response-level injection targeting autonomous agent workflows.
Side effects
- Missing or null 'content' field returns an error or undefined behavior
- Extremely large payloads may time out or be truncated
- Obfuscated or encoded injection attempts may evade detection and return low risk incorrectly
- Service unavailability on Render free-tier hosting may cause 502 or timeout errors
- Non-JSON content types passed as 'content' may not be analyzed correctly
