# Website Security Grade Checker

> Website Security Grade Checker is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns an A–F security grade, numeric score, and ranked remediation list for a website based on HTTPS, HSTS, CSP, security headers, cookie flags, TLS, and DNS hygiene checks.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability website-security-grade-checker-ba70bc95
```

Example prompt: Can you run a full security grade check on acme.com — I want the A–F letter grade, the score, and a list of what to fix first, including headers, TLS, and DNS hygiene?

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call security posture summary for a web domain combining HTTP headers, TLS, cookies, and DNS hygiene into one graded result. It is ideal for scheduled regression monitoring, vendor due diligence, or pre-launch audits where you want a ranked fix list rather than raw header dumps. Prefer it over individual SSL-only or DNS-only checkers when you need a holistic A–F grade that is easy to track and compare over time.

## Known failure modes

- Domain does not exist or is unreachable — returns error or degraded result
- Private/internal hostnames not accessible from scanner — cannot complete check
- Domain with aggressive bot-blocking may interfere with header inspection
- TLS handshake failure for expired or misconfigured certificates may cause partial results
- Rate limits or payment issues ($0.01 USDC per call) may block requests

## How this service works

Security grade A-F for a website in one number: HTTPS upgrade, HSTS, CSP, frame/content-type/referrer/permissions headers, cookie flags, server-version exposure, TLS certificate validity and days left, and DNS hygiene (SPF, DMARC, DNSSEC, CAA). Returns the grade, score, and a ranked list of reasons to fix. Track it on a schedule to catch regressions. $0.01 per domain.

## Output

Returns a letter grade (A–F), a numeric security score, TLS certificate validity and days remaining, and a ranked list of specific security issues to fix — covering HTTPS upgrade enforcement, HSTS, Content Security Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, cookie Secure/HttpOnly flags, server version header exposure, and DNS hygiene (SPF, DMARC, DNSSEC, CAA records).
