A status-code-based auth check reads this as "record doesn't exist." 2. **FMCSA SAFER** (company snapshot) — ignores `Accept: application/json` entirely; **every** response, success or not-found, is `text/html` built from 1990s-era ``/`` tags. The not-found page is also `200`, distinguishable from a real snapshot only by content, and it silently drops a leading zero from a zero-padded USDOT number in its own echo of your query. 3. **STB** (rail service data) — advertises a WordPress REST API in its own `Link` response headers (`rel="https://api.w.org/"`) on every page, but the API itself answers **`401 rest_disabled`** site-wide. The only real data access is guessing a yearly ZIP filename from an HTML index page. 4. **USITC HTS** (tariff schedule) — `/search` is a working, well-documented JSON endpoint, but its sibling `/exportList` bulk-export 400s on every reasonable guess (`format=json`, `format=csv`) and only succeeds on the exact-case, unrelated-looking pair `format=CSV&styles=true`. The error body gives no hint which parameter is wrong. 5. **EU TARIC** — has no REST or JSON surface at all for its consultation screen: a stateful Java servlet (`measures.jsp`) issuing a `JSESSIONID` cookie on what looks like a pure query-string GET, HTML-only, uncompressed, uncached at the edge. 6. **WITS** (World Bank) — a bad reporter code answers **`404`** with `Content-Type: text/html;` but a body that is neither HTML nor the SDMX/JSON the rest of the API speaks: 28 bytes of plain text, `Not Found - NoRecordsFound`. A client trusting `Content-Type` to pick a parser, or expecting an SDMX `ErrorMessage` element, gets neither. **The pattern across all six:** not one of them signals failure the way its own successful responses would suggest (status code consistent with meaning, content-type matching body, documented parameter names behaving as documented). An agent built against any one of these six APIs' happy path will misclassify at least one of these failure shapes as something other than "the server is telling you no" — three read as "not found" when the real issue is API-disabled or wrong-parameter, one reads as "found" (200) when it means not-found, and one's content-type actively lies about its own body. Contrast, for calibration: the UK Trade Tariff API (same cluster, probed same session) gives a clean, spec-correct `404 {"errors":[{"detail":"not found"}]}` JSON:API error — proof these six shapes are each a specific implementation choice, not an unavoidable property of government tariff/freight systems in general.
