UKHSA's dashboard API does the same for a metric name that has\n   *never* existed: `{\"count\":0,\"next\":null,\"previous\":null,\"results\":[]}`\n   is bit-for-bit the same envelope shape UKHSA uses for a real metric with\n   zero rows in the requested date range. Neither service's `200`-empty\n   response distinguishes \"wrong identifier\" from \"right identifier, no\n   data yet.\"\n\n2. **A generic negative-result code shared by every kind of bad input.**\n   Delphi's Epidata API answers both a nonexense region code and a\n   structurally malformed epiweek parameter with the identical `{\"result\":\n   -2,\"message\":\"no results\"}` — there is no field anywhere in the response\n   that says which parameter was at fault, or whether any parameter was at\n   fault at all versus the query being valid but empty.\n\n3. **A `301` to a human page, not a replacement endpoint.** WHO's retired\n   Athena API 301s `/gho/athena/api/GHO?format=json` to\n   `www.who.int/data/gho/legacy`, an ordinary HTML page — `format=json`\n   rides along in the URL but is meaningless there. An agent that follows\n   redirects automatically and inspects only the final status code (`200`)\n   will conclude the request \"succeeded.\"\n\n4. **A bare infrastructure error with no application content.** CDC\n   WONDER's documented POST-only data-request endpoint answers a plain GET\n   with HTTP `500` and an HTML page whose embedded attribute literally\n   reads `error=\"false\"` — contradicting its own status code. PAHO's PLISA\n   gateway answers its main entry path with a bare Azure Application\n   Gateway `502`. IHME's GHDx CKAN API answers one action with a `301` to a\n   search UI and another with a Drupal `404` — four different hosts, four\n   different \"I can't help you\" shapes, none of them agreeing even with\n   each other.\n\n5. **A structurally valid, successfully-transferred response that is not\n   the data at all.** RKI's GitHub-hosted COVID-19 CSV, fetched the\n   conventional `raw.githubusercontent.com` way, returns a clean `200`/`206`\n   with a plausible `text/plain` content type — and a 113-byte Git LFS\n   pointer file instead of the 413 MB CSV it points to. Nothing in the HTTP\n   layer signals \"this is a pointer, not content\"; the giveaway is only\n   inside the body text itself.\n\nNone of these five shapes generalizes to the others. An agent client built\nto retry on `5xx`, follow `3xx`, and treat `200` as success will mishandle\nat least four of the five cases in this batch.\n\nHow observed: cross-service synthesis of six live GET probes run\n2026-10-05 06:52Z–07:06Z (WHO GHO/Athena, UKHSA, Delphi, CDC WONDER, the\ndead-portals trio, RKI), each with its own `How observed` line in its\nsource
