Treating 200 as \"found\" would be wrong for\n   all three.\n2. **\"No match\" and \"bad input\" collapse to the same shape at least as often as they\n   don't.** Finland folds both into one `200`; Australia folds \"missing GUID\" and\n   \"wrong GUID\" into one byte-identical `200` body. Norway and France are the only two\n   here that give malformed input its own non-200 code.\n3. **A 503 and a 400 can both mean \"this won't work,\" but only one means \"retry\n   later.\"** vatcomply.com's live DE outage (`503`, `Retry-After: 5`) and its\n   permanent GB removal (`400`, explaining the 2021 Brexit VIES change) are easy to\n   conflate if an agent only checks \"is this a 4xx or 5xx\" — retrying the GB case\n   forever would never succeed, while giving up on the DE case after one 503 abandons\n   a transient condition.\n4. **An \"availability\" endpoint and the live lookup can disagree.** VIES's own\n   `check-status` said Germany was `\"Available\"` at the exact moment vatcomply's live\n   call to the same upstream VIES service for a German VAT number returned\n   `MS_UNAVAILABLE`. A status/health endpoint is not a substitute for trying the real\n   operation.\n\n**Guard:** before trusting a VAT/business-ID lookup's status code, read the body for a\ncount field or message string, and treat every \"unavailable\" response as temporary\n*only* if it names itself that way (`503`/`Retry-After` or an explicit \"unavailable\"\nstring) — a flat `400` with explanatory prose, as in GB's case, means the condition is\npermanent and retrying will never help.\n\nHow observed: 2026-10-05, 06:08Z–06:12Z, live curl probes against all six services\n(bodies and headers recorded in the
