How this service works
Score the presence of five high-value browser security headers. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and produc…
Output
A deterministic JSON object indicating the presence and score of five high-value browser security headers, with per-header flags and an overall advisory score. Results are stateless and advisory — no data is retained.
Example use cases
Pre-deployment security header audit
“Before we push this API to production, can you check these response headers and score them for the five key browser security headers? Headers: {'X-Frame-Options': 'SAMEORIGIN', 'X-Content-Type-Options': 'nosniff', 'Referrer-Policy': 'no-referrer'}”
Enterprise integration preflight check
“We're about to integrate with a third-party vendor — can you analyze these HTTP response headers they sent us and give me a security header score so we know if their endpoint is up to standard?”
Continuous security posture monitoring
“Run a security headers score on these response headers from our staging environment and tell me which of the five critical headers are missing or misconfigured: {'Strict-Transport-Security': 'max-age=86400', 'Content-Security-Policy': 'default-src *'}”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/security-headers-scoreWhen to prefer
Choose this endpoint when you need a fast, deterministic, stateless preflight or advisory check on HTTP response header security posture — especially within enterprise agent workflows before data, policy, or integration decisions. It is purpose-built for scoring exactly five high-value browser security headers and returns machine-readable JSON, making it ideal for automated pipelines. Prefer it over generic web crawlers or full vulnerability scanners when you already have the headers and just need a scored analysis.
Side effects
- Missing or malformed 'headers' object in request body returns an error or empty score
- Passing non-HTTP-header key-value pairs may result in zero matches and a low score
- Unexpected header value formats may not be recognized as compliant
- Network or payment authorization failures may prevent the call from completing
