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: 'allow' (boolean), 'decision' (allow/block), 'reasons' (list of strings explaining why, e.g. 'tool_calls_limit_exceeded: 100/100'), 'risk_level' (e.g. high/low), 'primitive' (quota-check), and 'recommended_action' (e.g. halt_agent_execution).
Example use cases
Example prompt
“Before my agent makes another tool call, check whether agent 'agent-42' using tool 'web_search' has exceeded its quota — give me the risk level and whether to allow or block the next action.”
Technical details
Endpoint
POSThttps://agent-security-gateway.onrender.com/api/quota/checkWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call quota enforcement gate for AI agents — specifically to check whether a given agent or tool has exceeded its allowed number of tool calls before proceeding. Prefer this over custom rate-limiting middleware when you want out-of-box USDC/x402 payment integration and don't want to manage quota state yourself.
Side effects
- Missing required 'response_content' field returns a 422 validation error
- Agent or tool not found returns allow=true with no reasons (unknown agents pass by default)
- Payment failure via x402 (insufficient USDC balance) returns 402 Payment Required
- Service unavailable on Render free tier cold starts causes timeout
- Malformed JSON body returns 400 Bad Request
