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 completeness assessment indicating whether the actual items fully cover the expected items for the task, likely including details on missing items, coverage percentage, or pass/fail status.
Example use cases
Example prompt
“Check if the agent's output is complete for the task 'extract all product names from catalog': the actual items returned are ['Widget A','Widget B'] and the expected items are ['Widget A','Widget B','Widget C','Widget D'] — use exact match type.”
Technical details
Endpoint
POSThttps://agent-security-gateway.onrender.com/api/validate/completenessWhen to prefer
Use this endpoint when an AI agent needs to programmatically verify that its output is complete before proceeding — especially in multi-step pipelines where missing items could cause downstream failures. Prefer this over manual checks when expected outputs are enumerable and can be compared item-by-item. Best suited for agents that need pay-per-use security validation without standing up their own validation infrastructure.
Side effects
- Missing required fields (task, actual_items, or expected_items) returns 400 validation error
- Payment failure via x402 protocol returns 402 Payment Required
- Empty arrays for actual_items or expected_items may return edge-case results
- Invalid match_type value may cause unexpected comparison behavior
- Service unavailability on Render free-tier hosting may cause timeouts or cold-start delays
