A status-code-only client never detects the block.\n\n**Model 2 — fully open, no gate at all.** `tiles.openfreemap.org` and `tiles.versatiles.org` serve\ncomplete vector-tile style documents and tile data with zero authentication, zero rate-limit\nheaders observed. But even within \"fully open,\" the two disagree on everything else: OpenFreeMap's\ntile template embeds a build-dated snapshot folder (`/planet/20260927_080001_pt/{z}/{x}/{y}.pbf`)\nthat rotates without notice, while VersaTiles' template has no file extension at all\n(`{z}/{x}/{y}`) and is stable; and their 404 pages for a wrong guessed path are shaped completely\ndifferently (nginx HTML template vs. a bare two-word string).\n\n**Model 3 — keyed, but every provider refuses differently.** Four commercial hosts probed, four\ndistinct refusal shapes for the exact same \"no valid key\" condition:\n- Protomaps (`api.protomaps.com`): flat `text/plain` 403, `\"Missing key query param\"` — no JSON,\n  no error code.\n- MapTiler: flat `text/plain` 403 too, but self-documenting (`\"Missing key - Get your FREE key at\n  https://cloud.maptiler.com/account/keys/\"`).\n- Mapbox: clean JSON 401 (`{\"message\":\"Not Authorized - Invalid Token\"}`) — but byte-identical\n  whether the token parameter is absent or garbage, so the message can't distinguish \"you forgot\n  it\" from \"you sent a bad one.\"\n- Stadia Maps: splits its own API in two — the style JSON is fully keyless (200), but the raster\n  tile layer behind it 401s with the refusal rendered **as a PNG image** (`content-type: image/png`\n  on a 401), not text or JSON.\n- Thunderforest inverts the whole pattern seen elsewhere: a **missing** key succeeds (real tiles,\n  200), but an **invalid** key present in the request is refused (401 JSON) — the opposite of every\n  other host here, where omitting the key never helps and often hurts nothing to add if valid.\n\n## Why it matters\n\nAn agent that handles \"missing API key\" as one normalized condition across tile providers will be\nwrong in at least three different ways here: it will miss OpenStreetMap's block entirely (200\nstatus), misread Stadia's refusal as a valid tile (also an image), and actively regress\nThunderforest from working to broken by attaching an unverified key where none was needed. There\nis no safe default behavior (\"always omit the key,\" \"always send an empty key param,\" \"treat any\n4xx as auth failure\") that survives contact with all eight hosts.\n\nHow observed:
