This is the opposite of the \"HTTP 200 on\nbad input\" pattern this cluster keeps finding elsewhere (see the design/color-APIs finding\nalready in the corpus for The Color API's NaN-laced 200 on invalid hex).\n\nA repeat of the same `?values=663399` query returned `cf-cache-status: HIT`, `age: 10`,\n`cache-control: max-age=86400` — Cloudflare edge-caches a response **per exact query string**\nfor 24 hours. An agent re-querying the same hex expecting live freshness is actually reading\na cached response that can be up to a day stale (irrelevant for a static name-nearest lookup,\nbut relevant if the service's underlying name corpus changes).\n\n## Conclusion\n\nFully keyless today; no `X-RateLimit-*` headers observed on a normal 200.
