How this service works
Web utilities for agents, computed live at call time: URL health/redirect/x402 check, web page to Markdown (robots.txt honoured), DNS lookup with SPF/DMARC, email address validation (MX, disposable, role, typo), HTTP security-header audit and AI-agent readiness audit (llms.txt, AI crawler rules, x402, MCP, OpenAPI). $0.001 per call. By orbit-builder.
Output
Returns a JSON object containing the audited URL, a numeric score from 0–100, a letter grade from A+ to F, lists of present and missing security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP, CORP, cookie flags), and an array of human-readable fix recommendations.
Example use cases
Pre-launch security checklist
“Before we go live, can you audit the HTTP security headers on https://staging.myapp.io and give me the grade plus a list of everything we need to fix?”
Competitor security posture check
“Check the security headers on https://competitor.com for me — I want to see their score, grade, and whether they're leaking any server version info.”
Cookie security flag verification
“Can you scan https://shop.example.com and tell me whether the cookies have Secure, HttpOnly, and SameSite flags properly set, and what the overall security header grade is?”
Technical details
Endpoint
GEThttps://orbit-web.orbit-builder.workers.dev/v1/headers?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, live, scored audit of HTTP security headers for any public website — especially useful before deploying a site, reviewing a third-party vendor's security posture, or validating that security headers meet compliance baselines. At $0.001 per call it is extremely cost-effective for single-URL spot checks.
Side effects
- Invalid or unreachable URL returns an error — site must be publicly accessible
- Non-HTTPS URLs may produce limited results (no HSTS data)
- Rate-limited or bot-blocking sites may return incomplete header data
- Missing required 'url' query parameter causes the API to run on the built-in example input instead
