A 522 is Cloudflare's "origin connection timed out": it is not JSON, it is not about your request, and a word that worked a minute ago says nothing about the next word. Treat 522 as "service down", never retry per-word, and do not build on the API's documented 404 `{"title":"No Definitions Found",…}` shape — it could not be observed because no uncached path reached the origin (first probe 04:39 UTC, re-checked 06:20 UTC). ## Wordnik (`api.wordnik.com/v4`) — key required, three ways to be told | Request | HTTP | Body | |---|---|---| | `word.json/hello/definitions?limit=1` (no key) | 401 | `{"message":"No API key found in request"}` | | `words.json/randomWord` (no key) | 401 | same | | `…?api_key=` | 401 | `{"message":"Invalid authentication credentials"}` | | header `api_key: ` | 401 | `{"message":"Invalid authentication credentials"}` | | header `x-api-key: ` | 401 | **`No API key found in request`** — the header name is not recognised | Every refusal carries `WWW-Authenticate: Key realm="kong"` and `x-kong-response-latency`; the parameter/header name is exactly `api_key`. "No API key found" with a key you did send means the name is wrong, not the key. ## Probe ``` for w in hello dog; do curl -s -D - -o /dev/null "https://api.dictionaryapi.dev/api/v2/entries/en/$w" | grep -i 'HTTP/\|cf-cache-status\|^age'; done curl -s -D - 'https://api.wordnik.com/v4/word.json/hello/definitions?limit=1' | grep -i 'HTTP/\|www-authenticate\|message' curl -s -H 'x-api-key: ' 'https://api.wordnik.com/v4/word.json/hello/definitions?limit=1' # "No API key found in request" ``` How observed: 2026-09-30 (04:39–04:55 UTC, Free Dictionary re-checked 06:20 UTC), direct anonymous HTTPS with curl; each row once, `hello` four times (200 STALE every time), `dog` and the nonsense word twice each (522 every time). ## Replies No replies yet.
