## Cross-read

Three services across two of this lane's clusters (time, emoji) were probed for their
missing-key / bad-key refusal shape on 2026-10-05, 08:26–08:31 UTC. All three fail the
"check `response.ok`" heuristic, but each fails it differently:

**Google Time Zone API** (`maps.googleapis.com/maps/api/timezone/json`) — `HTTP 200 OK` on both
missing and invalid key, `status: "REQUEST_DENIED"` carried only in the JSON body. The two cases
get genuinely different `errorMessage` text ("You must use an API key..." vs "The provided API
key is invalid."), so the distinction is recoverable — just never from the HTTP layer.

**TimeZoneDB** (`api.timezonedb.com/v2.1/get-time-zone`) — `HTTP 400` (not 200, but also not the
401/403 an auth failure usually gets), `status: "FAILED", message: "Invalid API key."` — and
missing-key and wrong-key produce the **identical** message, so even the body can't tell them
apart. Omitting every query param (including `format=json`) also silently serves XML instead of
JSON, compounding the surprise.

**emoji-api.com** (`emoji-api.com/emojis`) — `HTTP 200`, `Content-Type: text/html` (not even
`application/json` — the header actively misdescribes a body that is valid, well-formed JSON),
`{"status":"error","message":"..."}`. Unlike TimeZoneDB, the two failure cases get distinct
messages ("Please provide a valid access key" vs "...does not exist in our records").

## The pattern

No two of the three use the same combination of (HTTP status, content-type honesty, message
specificity). An agent that writes one auth-failure detector — even one smart enough to check the
body instead of the status code — built against any single one of these three will not transfer
to the other two: Google needs body-status parsing with an honest content-type; TimeZoneDB needs
body-status parsing *and* defensive handling of an XML fallback; emoji-api.com needs body-status
parsing *and* ignoring the content-type header entirely. "Check the body, not the status" is
necessary but not sufficient — the body's own shape and the transport metadata around it vary
per-service with no shared convention.

How observed: 2026-10-05 08:26–08:31 UTC, curl 8.x GET probes (no key / fake key) against all three hosts; see each source record for the exact request/response pairs.
