Website Security Audit

What it runs

1. 1
   SSL Certificate Check

   Source: TLS handshake (X.509 certificate from target server)

2. 2
   Security Header Check

   Source: HTTP response headers from target server (CSP, HSTS, X-Frame-Options)

3. 3
   DNS Lookup

   Source: DNS protocol (authoritative nameservers)

4. 4
   Tech Stack Detection

   Source: HTTP response analysis (headers, JavaScript libraries, meta tags)

The answer returns every step’s result, so your agent can show or check each one.

Inputs

How to call it

# Needs an API key. The whole check is charged once, at the listed price.
curl -X POST https://api.strale.io/v1/solutions/website-security-audit/execute \
  -H "Authorization: Bearer $STRALE_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "inputs": {
      "url": "https://example.com"
    },
    "max_price_cents": 20
  }'

# No account. The first request answers 402 with the price in USDC;
# an x402 client pays it from your wallet and repeats the request.
curl -i -X POST https://api.strale.io/x402/v2/solutions/website-security-audit \
  -H 'Content-Type: application/json' \
  -d '{
    "url": "https://example.com"
  }'

Limitations

• Checks the certificate presented on port 443 only — does not verify non-standard TLS configurations

  From step: SSL Certificate Check

  What to do instead: For services on non-standard ports, use ssl-certificate-chain with the specific hostname:port combination

• Checks HTTP security headers only — does not assess server configuration, TLS settings, or application-level vulnerabilities

  From step: Security Header Check

  What to do instead: Combine with ssl-check for TLS assessment and use a full DAST scanner for application-level security testing

• Results reflect current DNS propagation — recent changes may take up to 48 hours to appear

  From step: DNS Lookup

  What to do instead: Query the authoritative nameserver directly (returned in the NS records) to see changes before full propagation

• Trustpilot, Glassdoor, LinkedIn, Google Search, Google Patents, Reddit and the major social platforms (Facebook, Instagram, X) are not supported and return a policy error before the page is read. Repeating the same request does not return content.

  From step: Tech Stack Detection

• Database covers 1,000+ technologies — niche or custom-built tools may not be identified

  From step: Tech Stack Detection

  What to do instead: Check the raw HTTP headers in the response for custom X-Powered-By or Server values that indicate unlisted technology

• Detection based on HTTP headers, JavaScript libraries, and HTML signatures — technologies loaded conditionally or server-side only may not be detected

  From step: Tech Stack Detection

  What to do instead: Complement with dns-lookup and ssl-check results to infer infrastructure choices not visible in the HTML

• Pages with more than 16 MiB of HTML are refused with a caller_input error naming the input field. The call is not charged, and the page is not retried through another fetch or rendering route.
