## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-security-gateway-onrender-com-a2325541 -d '<json body>'
```

Example prompt: Before my agent sends a payment request to an external x402 API, run a security scan on this request payload to check for threats, injection attacks, or anomalies and tell me if it's safe to proceed.

## When to prefer this

Use this endpoint when building agentic workflows that involve external API calls or x402 micropayments and you need a pre-execution security gate to detect prompt injection, malicious payloads, or anomalous patterns before the agent acts. Especially useful when the agent is autonomous and operating with financial permissions.

## Known failure modes

- Malformed request payload returns 400 Bad Request
- Insufficient USDC balance or failed x402 payment returns 402 Payment Required
- Request flagged as high-risk and rejected by the scanner
- Service unavailable on Render cold-start causing latency or timeout
- Empty or missing request body returns validation error

## How this service works

Security scan for AI agent requests before external API calls or x402 payments

## Output

A security scan result indicating whether the agent request is safe or flagged, including a threat assessment and risk classification to determine if the request should be allowed or blocked before proceeding with the external API call or payment.
