## 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 bulk-security-headers-grader-ce044080
```

Example prompt: Can you grade the security headers on these five sites — example.com, shopify.com, stripe.com, acme.io, and vendor-xyz.com — and tell me which ones are missing HSTS or CSP, ranked from worst to best?

## When to prefer this

Choose this endpoint when you need to audit HTTP security headers across multiple URLs in a single call without building your own header-fetching pipeline. It is especially suited for vendor sweeps, agency portfolio audits, and pre-launch checklists where you want a human-readable A–F grade and a prioritized list of missing headers. Prefer it over single-URL checkers when comparing several domains at once or when the sorted worst-first ranking is useful for triage.

## Known failure modes

- Unreachable URL returns an error or no-grade for that entry
- More than 10 URLs submitted may be rejected or truncated
- Misconfigured input schema (non-HTTP URLs, typos) causes partial failures
- Server that blocks automated requests may return misleading header absence
- Dynamic pages with server-side header injection may not reflect actual browser-received headers

## How this service works

Bulk security-header grade for up to 10 URLs in one call: each URL gets an A-F grade from HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and server-version exposure, with the specific missing headers, sorted worst-first. Vendor sweeps and portfolio audits. $0.01 per batch.

## Output

For each submitted URL, the agent receives an A–F security grade, a list of missing or misconfigured headers (from HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, and server-version exposure), and results sorted worst-first so the highest-risk URLs are surfaced at the top.
