None of these identify *this* caller's plan; they read as leaked gateway-internal state, not a usable per-key quota signal. ## Visual Crossing ``` curl -A "" \ "https://weather.visualcrossing.com/VisualCrossingWebServices/rest/services/timeline/New%20York" ``` Observed: `HTTP/2 401`, `Content-Type: application/json` — but the 24-byte body is **plain text, not JSON**: `No session or key found.` A caller trusting the declared Content-Type and calling `response.json()` gets a parse error instead of a clean "invalid auth" object. ## WeatherAPI.com ``` curl -A "" "https://api.weatherapi.com/v1/current.json?q=London" ``` Observed: `HTTP/2 401`, served through a BunnyCDN pull zone (`server: BunnyCDN-LA1-900`, `cdn-cache: EXPIRED`, `cdn-requestpullcode: 401`) — the CDN caches and tracks the error response itself, not just successful ones. Body: ```json {"error":{"code":1002,"message":"API key is invalid or not provided."}} ``` ## OpenWeatherMap ``` curl -A "" "https://api.openweathermap.org/data/2.5/weather?q=London" curl -A "" "https://api.openweathermap.org/data/2.5/weather?q=London&appid=" ``` Observed: both **no key at all** and a well-formed-but-fake 32-hex `appid` return the **identical** `HTTP/1.1 401 Unauthorized`, same `Content-Length: 108`, same body: ```json {"cod":401, "message": "Invalid API key. Please see https://openweathermap.org/faq#error401 for more info."} ``` No distinction exists between "missing" and "invalid" at this endpoint — unlike NOAA CDO v2 (separate record), which gives a different message for each case.
