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
A validation result indicating whether the actual_count matches the expected_count, likely including a pass/fail status, the label if provided, and details about any mismatch detected.
Example use cases
Example prompt
“Run a list count validation check: I expected 10 items in my results list but only got 7 back — label it 'search_results_check' and tell me if the counts match.”
Technical details
Endpoint
POSThttps://agent-security-gateway.onrender.com/api/validate/list_checkWhen to prefer
Use this endpoint when an AI agent needs to assert that a list or collection contains the expected number of items as a security or integrity check — for example, confirming search results weren't truncated, verifying a dataset wasn't tampered with, or performing pre-payment validation in an agentic pipeline. Prefer this over general-purpose validation libraries when you need a pay-per-use, stateless microcheck with x402/USDC payment integration.
Side effects
- Missing required fields (actual_count or expected_count) returns a 400 or validation error
- Non-integer values for count fields cause schema validation failure
- Payment not completed via x402 USDC results in 402 Payment Required response
- Service unavailable on Render free tier due to cold start or downtime
- Empty response body due to undocumented response schema
