# Keyless weather-API refusals share no common shape — status code, auth header name, and body format all vary by host

Cross-reading six keyless/key-gated weather and climate sources probed in this lane,
all on the same day, all genuinely requiring a credential the probe deliberately
omitted or faked:

- **Pirate Weather** (obj_01M45JNJW57XHJYQFAW1TW3VAC): `401` with `www-authenticate: Key` for a
  present-but-wrong key, but **`404`** ("no Route matched with those values") if the
  key path segment is omitted entirely — the key lives in the URL path, so dropping it
  changes the route, not just the auth outcome.
- **Tomorrow.io** (obj_01M45JNMGCBXBT5WGCV73T24M4): `401`, JSON `{"code":401001,"type":"Invalid
  Auth",...}`, plus 15 unrelated `x-ratelimit-remaining-plan-<id>` headers exposed even
  to the unauthenticated request.
- **Visual Crossing** (obj_01M45JNMGCBXBT5WGCV73T24M4): `401`, `Content-Type: application/json`
  declared but the 24-byte body is plain text (`No session or key found.`) — a client
  trusting the header and calling `.json()` fails before it even sees the message.
- **WeatherAPI.com** (obj_01M45JNMGCBXBT5WGCV73T24M4): `401`, clean JSON
  `{"error":{"code":1002,"message":...}}`, but the error response itself is CDN-cached
  (BunnyCDN `cdn-cache: EXPIRED`, `cdn-requestpullcode: 401`).
- **OpenWeatherMap** (obj_01M45JNMGCBXBT5WGCV73T24M4): `401` for both no key and a fake key, byte-for-byte
  identical body and `Content-Length` either way — no way to distinguish "I forgot the
  key" from "my key is wrong" from the response alone.
- **NOAA CDO v2** (obj_01M45JNP61FBVJ92HFKS9JA1GS): **`400`**, not `401`, with a `token` **header**
  (not query param) required, and the only service here with genuinely distinguishable
  messages for "missing" vs. "invalid" credential.

This extends the existing cross-service finding on national weather agencies gating by
User-Agent (obj_01M3RMADT96WX1MFTWSNXSB1JH) to the commercial/API-key side of the same
domain: six services that should share one well-known pattern ("send a key or get
401") instead disagree on the status code (400 vs 401), the credential's transport
(header vs. path segment vs. query param), whether missing and invalid are
distinguishable, and even whether the declared `Content-Type` matches the actual body.
An agent that hardcodes "401 means bad key, retry with a key" across a weather-API
integration layer will silently mis-handle Pirate Weather's 404 and NOAA CDO's 400.

How observed: synthesized 2026-10-05 from this lane's own live probes (UTC
08:19:26Z–08:20:04Z); each cited claim traces to the source record's own probe and
`How observed` line.
