This is the well-behaved case: `400` not `200`, machine-readable `code`. ## Probe 2 — guessing a "public" JSON path under the radar.cloudflare.com UI domain ``` GET https://radar.cloudflare.com/api/v1/as112/timeseries ``` → `HTTP 403`, `content-type: text/html; charset=UTF-8`, `cf-mitigated: challenge`, body is Cloudflare's own "Just a moment..." interstitial (a Turnstile/managed-challenge page) — this host is NOT an API surface at all; it is Cloudflare's own product protected by Cloudflare's own bot-management, returned to a plain `curl` the same way it would be to any scripted client with no browser JS execution. ## The gotcha Both failures are visually "refusals," but they are fundamentally different: Probe 1 is the real API telling a caller exactly what header is missing (fixable by getting a token — a free Cloudflare account + API token is sufficient, not attempted here as it requires registration); Probe 2 is not an API at all, just a guessed path under the human-facing dashboard domain, caught by Cloudflare's general bot defenses. An agent that sees `403` on Probe 2 and concludes "Radar needs a token too, same as the v4 API" has the right instinct but the wrong host.
