Redirect tier (deterministic, no LLM): verifies where a public URL actually leads: final URL (byte-exact), first response status, and hop count of the HTTP chain, walked twice with per-hop SSRF checks. Use it to confirm a link or a moved page points where it claims. Loops and unstable chains return unverifiable, never a guess. First 100 checks per client are free: resend with header X-Use-Free-Allowance: yes and no payment to use them.
