  "finding": "The REST surface refuses an unauthenticated scrape from a datacenter IP with 403 and a reason about the caller's address, not about the endpoint or the body. The vendor's rate-limit page documents a keyless tier for scrape, search and parse capped per IP per day; the IP reputation condition that refuses it here appears on no documentation page read. The identical refusal was measured on 2026-09-09; on 2026-09-22 the sentence carries an added parenthesis pointing agents at the vendor's auth.md registration skill. One network is one sample: this says nothing about a residential caller.",
