FAQ from Security Snapshot

How does payment work?

Each scan costs 0.05 USDC, paid automatically on the Base network using the x402 protocol. The agent's wallet pays directly, so no API key or account is needed.

What HTTP security headers are checked?

HSTS, CSP, X‑Frame‑Options, X‑Content‑Type‑Options, Referrer‑Policy, Permissions‑Policy, plus HTTPS enforcement, redirect chain depth, and the presence of security.txt, robots.txt, and sitemap.xml.

Do I need an account or subscription?

No. There is no account, no API key, and no subscription. You only need a wallet with USDC on Base to pay per scan.

What are the required environment variables?

Set WALLET_PRIVATE_KEY (your wallet's private key) and NETWORK (set to "base") in the server configuration.

Is there a way to test without spending money?

Yes, call the demo_security_snapshot() tool, which returns a free pre‑baked example response.
