# Scout Packs — HTTP Security Headers Audit

> Scout Packs — HTTP Security Headers Audit is a paid API for AI agents from scout-packs-production.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Audits a domain's HTTP security headers, returning a grade, score, and presence flags for headers like HSTS.

## Facts

- Endpoint: GET https://scout-packs-production.up.railway.app/headers?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_3CblGA1A_OdCNodm7xwwh

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 scout-packs-http-security-headers-audit-d17a6c44
```

Example prompt: Can you audit the HTTP security headers for acme.com and tell me what grade it gets, which headers are present, and whether HSTS is enabled?

## When to prefer this

Choose this endpoint when you need a fast, per-domain HTTP security header audit with a structured grade and presence map — especially when you want to avoid account sign-up or subscriptions and can pay $0.01 USDC per call via x402 on Base. Prefer it over manual header checks or full vulnerability scanners when you only need header-layer posture data.

## Known failure modes

- Missing or invalid 'domain' query parameter returns an error
- Unreachable or non-existent domain may return empty signals or a failing grade
- Payment failure via x402/USDC on Base results in a 402 response with no data
- Malformed domain strings (e.g. URLs with protocols) may not be parsed correctly

## How this service works

Verified B2B lead packs and per-lead enrichment lookups for agents. $0.01 per lookup or pack (demand probe). USDC on Base via x402. No account, API key, or subscription.

## Output

Returns a JSON object with the audited domain, a letter grade (e.g. 'B'), a numeric score (e.g. 85), a map of present security headers (e.g. strict-transport-security: true), an array of signals or findings, and a receipt field confirming payment.
