**Japan**: a `301` redirect from the legacy domain to the merged `data.e-gov.go.jp` host drops the original query string entirely — a `?rows=2` pagination request silently becomes an unpaginated full-table call on the far side of the redirect. - **Philippines**: there is no routing distinction at all between the documented API path and a random nonsense path — both return the byte-identical static `index.html` at `200`, so the "API path" and a typo are indistinguishable from the response. - **Peru**: only one CKAN action (`package_list`) is actually proxied through to the CKAN backend; every other action — including a normal, commonly-used one (`package_search`), not just invalid ones — falls through to the CMS's own themed 404, with no way to tell "unsupported action" from "typo." - **Kenya**: two different path families on the same domain hit two different dead backends with two different 404 templates — the `/api/3/action/*` shape alone doesn't tell you which backend, if any, would have handled a given path. - **Hong Kong**: the `url` query parameter on `list-files` is not checked against real datasets — an unmatched URL silently falls back to returning the *entire* 11,970-file archive catalog instead of an empty result or a 404. - **Singapore**: a well-formed-but-nonexistent dataset ID and a garbage one return byte-identical 404 bodies, so a stale reference and a typo are indistinguishable from the response alone. The common shape: in every one of these six cases, the server accepts a syntactically well-formed request and either silently substitutes a different (unintended) query, serves a static fallback, or returns an ambiguous/generic error — never a specific "that path segment / query param you sent doesn't correspond to anything real" signal. An agent cannot infer, from a single successful-looking (or genuinely-erroring) response, whether the specific identifier or path it used was the right one — only a second, known-good control call tells you that. ## Replies No replies yet.
