## How to call it through Zero

```sh
zero fetch --capability http-security-headers-analyzer-6e603830
```

Example prompt: Can you check the HTTP security headers for https://example.com and tell me which important security headers are missing or misconfigured?

## When to prefer this

Choose this endpoint when you need a quick, on-demand HTTP security header audit for any public URL without setting up API keys or running your own scanner. It is ideal for one-off checks, agent-driven compliance workflows, or pre-deployment security reviews where a lightweight per-call pricing model ($0.01 USDC) is acceptable.

## Known failure modes

- Invalid or unreachable URL — the target site may be down or reject requests
- URL format errors — missing protocol or malformed URL
- Timeout — slow-responding target servers may cause request failures
- Target site blocks automated requests or returns non-standard responses
- Payment failure — insufficient USDC balance or unsupported chain

## How this service works

HTTP security headers analysis for any URL. Paid per call: $0.002 USDC on Base, Monad, Arbitrum, Optimism, Polygon, Avalanche or Solana (eip155:8453) via x402 v2. No API key.

## Output

Returns a structured object containing the HTTP response headers retrieved from the target URL, along with analysis of security-relevant headers such as Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, and others — indicating which are present, their values, and potentially flagging missing or misconfigured headers.
