How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the HTTP status code, all response headers as key-value pairs, the final URL after following any redirects, a list of security headers that are present, and a list of security headers that are missing (e.g. content-security-policy, referrer-policy, strict-transport-security, x-content-type-options).
Example use cases
Security audit before launch
“Before we go live with our new site at https://myapp.io, can you check its HTTP headers and tell me which security headers like CSP, HSTS, and X-Content-Type-Options are missing so I can fix them?”
Verify CDN cache headers
“Can you inspect the HTTP headers returned by https://cdn.mycompany.com/assets/main.js and tell me what the cache-control and server headers look like?”
Check if redirect changes security posture
“Hit https://shop.example.com with a 5-second timeout and tell me the final URL it lands on after any redirects, plus which security headers are present or missing at that destination.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/http-headers-inspect?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, cheap ($0.01 USDC) programmatic inspection of HTTP headers for any URL, especially for security audits that check for missing or misconfigured headers. Prefer this over manual browser devtools or curl when running automated agent workflows that need structured, machine-readable header data including a clear breakdown of security header presence and absence.
Side effects
- URL is unreachable or DNS fails — returns an error with no headers
- Timeout exceeded (max 15 seconds) — request is aborted and returns timeout error
- Invalid URL format — request rejected with validation error
- Target server returns non-200 status — still returns headers and status code but may indicate an error state
