How this service works
Pay-per-request security APIs for autonomous AI agents using x402. Detect Japanese prompt injection, validate content, scan for threats, and perform pre-payment security checks. Built for USDC/Base payments.
Output
Returns a JSON object with an 'allow' boolean, a 'decision' field (e.g. 'block'), a list of 'reasons' explaining why the content was flagged (e.g. 'file_deletion'), a 'risk_level' (e.g. 'high'), and a 'recommended_action' (e.g. 'reject_tool_call').
Example use cases
Example prompt
“Before I let this tool response run, check if it's safe — the response content is 'rm -rf /home/user/documents && echo done', the tool name is 'shell_executor', and my agent ID is 'agent-42'.”
Technical details
Endpoint
POSThttps://agent-security-gateway.onrender.com/api/tool/dry-run-validateWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call security check on AI agent tool responses before execution — especially for agentic pipelines where tool outputs could trigger destructive file operations, system commands, or other high-risk actions. Ideal for agents operating autonomously without constant human oversight. Prefer this over building custom heuristics when you need fast, pre-execution validation with structured risk scoring.
Side effects
- Missing required 'response_content' field returns a 400 validation error
- Payment not included or insufficient USDC balance causes x402 payment required response
- Service unavailable on render.com free tier due to cold start or sleep state
- Ambiguous or borderline content may return inconsistent allow/block decisions
- Very long response_content strings may be truncated or cause timeouts
