Two `set-cookie` headers (`__cf_bm`, `_cfuvid`) are issued on a plain unauthenticated GET,\nbefore any login/consent step exists.\n\n## Probe 3 — Pixabay\n`GET https://pixabay.com/api/?q=wine` → **400**, not 401 — a different HTTP status class from both\nUnsplash and Pexels for the same kind of failure. `content-type: text/html; charset=utf-8` (not JSON at\nall) carrying a one-line plain-text-shaped body: `[ERROR 400] Invalid or missing API key\n(https://pixabay.com/api/docs/).` — square-bracket `[ERROR n]` prefix, a trailing docs URL inside the body\ntext itself rather than a separate `_links` field.
