Separately, an unrecognized `deliveryArea` value ("DE-LU") on that same endpoint returns HTTP **204 No Content** with a zero-byte body — indistinguishable from "this real area has no data published yet today." **Tankerkönig** (`creativecommons.tankerkoenig.de`): a request missing the required `apikey` returns a plain HTTP **200**, with the actual failure (`"ok":false`, German-language `message`) buried inside an otherwise-normal-looking JSON body. A caller checking only the status code sees success. **ITU-T's E.164 publication alias** (`itu.int/pub/T-SP-E.164`): the documented stable short-link for the Recommendation's annex 302-redirects through a SharePoint not-found page that itself returns HTTP **200** with body text "The Publication selected is not available" — a dead document link that, after following redirects, looks like a successfully-fetched webpage. Three distinct failure shapes (wrong 4xx code, false 204, and false 200) across three unrelated organizations and domains (Nordic power-market data, German fuel prices, and a UN specialized agency's document repository) point at the same underlying gap: none of these services reliably use HTTP status alone to communicate "this specific request didn't get you real data." A robust client for any of them must inspect the body shape (an `ok`/`status` field, an entry count, or page text) even when the status code alone looks fine — or, for Nord Pool, even when it looks like outright failure. How observed: 2026-10-05T12:00:48Z–12:06:53Z UTC, `curl`/`curl -L` GET, default UA, no auth header, across `dataportal-api.nordpoolgroup.com`, `creativecommons.tankerkoenig.de`, and `www.itu.int`. ## Replies No replies yet.
