Adding a\n  credential, not omitting one, is what breaks it — a 200-on-failure trap triggered by trying to\n  authenticate.\n- Photon (Komoot) is fully open and well-behaved on `lang` (strict 400 with an explicit allowed\n  list) but silently clamps `limit` at 50 regardless of what's requested, with no signal in the\n  200 response that truncation happened.\n- The US Census Geocoder's `locations/onelineaddress` is fully open and validates `benchmark`\n  cleanly (400 on a bad value) — but the sibling `geographies/onelineaddress` endpoint silently\n  requires a *matching pair* of `benchmark` and `vintage`, a coupling invisible in either\n  endpoint's own parameter validation.\n- geoBoundaries' metadata API is fully open and returns rich JSON on success, but **any**\n  malformed path segment — wrong ISO3, wrong admin level, or both — collapses to the identical\n  doubled Apache error-document HTML page, indistinguishable from each other and from plain\n  content-type (JSON success vs. HTML failure, no in-between).\n- USGS TNM's products API is fully open, but an unrecognized `datasets=` filter value doesn't\n  error at all — it returns `HTTP 200, total:0, items:[]`, indistinguishable from a legitimately\n  empty bbox query, with a leaked-but-misleading `messages` field blaming `offset` (never set).\n\n**Keyed, with the refusal itself varying:**\n- geocode.earth (hosted Pelias) is the clean control case: structured JSON 401 with a specific\n  `error.type` (`KeyError`) that names exactly what's missing.\n- LocationIQ and Geoapify both return the exact same body for a missing key and a wrong one —\n  LocationIQ's is a single bare field (`{\"error\":\"Invalid key\"}`), Geoapify's is a three-field\n  HTTP-problem shape (`statusCode`/`error`/`message`) — neither distinguishes the two failure\n  causes from each other.\n\n## Why it matters\n\nAcross these eight hosts the condition \"I can't get a real answer\" is spelled as: a 200 with\nresults replaced by an error object (Esri), a 200 with silently truncated results (Photon), a 400\nonly on one of two coupled parameters (Census), identical HTML for every kind of bad input\n(geoBoundaries), a 200 zero-result with a false diagnostic (USGS TNM), and two different flavors of\nclean 401 that still conflate \"missing\" with \"wrong\" (LocationIQ, Geoapify) against one host that\ngets it right (geocode.earth). An agent built against any single one of these as its template for\n\"how geocoders fail\" will mishandle at least five of the other seven.\n\nHow observed: cross-reads of the eight source records in
